Fred (Gopher) will be co-host for the RAVE.  He has volunteered to bring the equipment that he has listed earlier in the thread to the RAVE and helping in coordinating with Lukasz.

None taken.

I know it will not make much of a difference but the event is not sponsored by any manufactures listed.  Speakers are my personal ones, Dac and transport are provided by Fred who owns them.  I have always reached out to Pete to see if he can lend me power cords, since I do not want my DIY power cords to be the limiting factor.  Lukasz is visiting US during the time so he accepted my invitation to attend.  The last time Lukasz had attend RAVE event couple of years ago he basically let us play with the DAC that he brought along and left us alone to enjoy the day and I do not see that changing this time around.

If you change your mind you have my address and phone number  :thumb:

Always happy to oblige... Thank you for hosting these great events... I like to leave early, avoid the traffic & hang (aka buying great LP's!) at the Princeton Record Exchange (PREX) prior to attending!

What time do the doors open?

On another note - Maybe the S.I. hump will attend???  :lol: I miss him! One of the better Raves I've attended was in the Brooklyn Navy Yard where Charles Xavier himself set one up at the DeVore MonkeyHaus... Geez, isn't DeVore a manufacturer???   :duh: :thumb:

Thanks again,
Pete

Was that the reason for you to start skipping  :slap:.  One of the items for lunch was Falafel but it will most likely be from Mamouns (http://mamouns.com/)

As for the mfg,  I am working with whatever is available or I am able to borrow.  Help me find other mfg who are willing to attend/loan equipment outside of the ones that we have hosted at RAVE's and I will try to have them attend so we get variety of equipment to listen too.  For now I would have to say that Zu is my preferred speakers so they will most likely will be at every event that is hosted at our place unless one of the mfg being hosted is a speaker company and at that point the Zu's will be pulled out of the rooms.  Outside of the speaker preference I am open to anything else.

As for the ruining the thread that is not going to happen.  All the banter back and forth is part of the hobby and adds flavor  :wine:

No one said to get rid of your speakers. They're part of your system. You don't need other manufacturers to have a rave, just have a rave. I have Petes cords but I would rather hear your homegrown cords instead if that's what your using. Get my drift.

Will add you to the list.  The RAVE's usually last well into evening so either you can join us early or late depending on your conflict.  Will send contact information out as we get closer to the day.

   Great stuff. The GM 70 should be a treat. Looking forward to this one. Love to hear that SET amp. They were favorite for quite some time SET that is. My Pipedreams just needed more power. Still huge SET fan. Maybe the Lamp may change my mind again, oh my !!

Charles,

It should be a very nice pair of amps indeed!  I'm pretty excited to hear this one too.  I think this will be paired with the Zu Soul Superflys and a very nice amplifier  by Taras will be mated with the GT Audio speakers you are bringing which should be fantastic.

I've heard Taras amp in my home and it is very good:

What is the tube complement in the Lampizator DAC?
Title: Re: LampizatOr Rave
Post by: shadowlight on 25 Sep 2013, 12:51 am
What is the tube complement in the Lampizator DAC?


I believe level 4 (http://www.lampizator.eu/newdac/dacstory.html) was based around 6H6P while level 5 (http://lampizator.eu/newdac/L5/L5_dacstory.html) and Big Six (http://www.lampizator.eu/NEWDAC/Lampizator/LEVEL_SIX.html) are based around 6H8C (6sn7)
Title: Re: LampizatOr Rave
Post by: Berto on 25 Sep 2013, 04:08 am
The 4 is based on the ecc40 and so is the the 5.  The L6 is 6sn7s or Russian 6H8c. That lil ecc40 tube can be found cheap and creates alot of magic.  For rectifiers 5y3 or 6x5s and variants like 6106 or 5852 Bendix . But being custom built, nothing is etched in stone.

Sorry I won't be able to make the rave. Will be holding an 80th Birthday party for my mom at that time. Sounds like it will be an incredible event.

I was also interested to see that the Ming Da 3008AB will be included. I have an older version that I got about 10 years ago sitting in a box somewhere. I should dust it off sometime and try it out again now that the Lampizator is in my system. I should try to sell it at some point as well as a bunch of other stuff in my storage space so I can get the Lampi DSD DAC at some point!

Have fun!

Many thanks to Deepak, Chhaya and family for their usual superb hospitality, great food and friendly nature.
It was so good to see all folks, especially from ny, I need to come back to ny every now and then.
Sound overall was better this time around compared to the last rave.

It was good to see Lukasz and hear some of the magic from the Lampi Dacs, transport and amp. :thumb:

Thanks to all who brought gear, dessert and more dessert.

Until next time ...

Deepak and Chhaya,

Thank you again for your warm hospitality, and opening your lovely home to a bunch of audiophools.
It was great to meet Lukaz and put faces to the the guys who post here.
This was my first rave, I hope to attend many more in the future, and show up earlier.   :duh:

Title: Re: LampizatOr Rave
Post by: Gopher on 21 Oct 2013, 02:15 pm
There are some pictures and comments over on Audionervosa.  Audiocircle was down yesterday.

Overall it was a lot of fun and a good event.  Deepak and his wife are WONDERFUL hosts and their beautiful home could not be more perfect for this type of event.  We even had a celebrity guest in the house.

The sound was good, but we encountered some issues and setbacks due to getting a little ambitious with three separate systems.  The promise was clear but the matching needed help.  The few guys that stayed till the very end got to hear what the Big Six could do in the basement rig after we swapped out the Zu Omen Defs.  I love Zu speakers, but we had a really rough time taming the top end.

The GM70s never got the opportunity to really strut their stuff as the speakers we had to switch to in the main rig were only 4ohm--it was unfortunate, but the monos will be around on LI for a bit.

As for a revelation:  I know the PCM DACs well but it was the first time hearing Lampi DSD and it really is something!  Fortunately that was playing for most of the day in the upstairs bedroom without room acoustic issues and was able to shine.

Post by: rollo on 21 Oct 2013, 02:36 pm
  Glad you all had a good time. We offered to bring GTA2 speakers for the event but did not work out. would have liked to hear the GM70 amps with them.
   When I get a pair in the house maybe you can bring over some gear or have a meeting.

This was my first NY/NJ rave and it was a blast.  :thumb:
Major props to Deepak and Chhaya for opening up their beautiful home for us.
I've been to a couple of CAFs and RMAF but nothing beats being able to interact with manufacturers and listen to some awesome gear in a friendly, home like setting. Was fun putting a face to audiocircle monikers.

Lukasz and Merrill are great guys to talk to and build some awesome products.

I finally understand the buzz around Lampi DACs and the GM70 amp. Amazingly natural sounding and just get out of the way of music. Lampi DSD is the real deal, very liquid and gripping presentation.
Oh, and Taras A100 is a killer amp too. Almost tube like in its ability to flesh out the textures.

Listening to all this great gear has given me some serious GAS (gear acquisition syndrome)  :green:

There are some pictures and comments over on Audionervosa.  Audiocircle was down yesterday.

Overall it was a lot of fun and a good event.  Deepak and his wife are WONDERFUL hosts and their beautiful home could not be more perfect for this type of event.  We even had a celebrity guest in the house.

The sound was good, but we encountered some issues and setbacks due to getting a little ambitious with three separate systems.  The promise was clear but the matching needed help.  The few guys that stayed till the very end got to hear what the Big Six could do in the basement rig after we swapped out the Zu Omen Defs.  I love Zu speakers, but we had a really rough time taming the top end.

The GM70s never got the opportunity to really strut their stuff as the speakers we had to switch to in the main rig were only 4ohm--it was unfortunate, but the monos will be around on LI for a bit.

As for a revelation:  I know the PCM DACs well but it was the first time hearing Lampi DSD and it really is something!  Fortunately that was playing for most of the day in the upstairs bedroom without room acoustic issues and was able to shine.

Since you have the GM70s for a while, I guess  the next Rave is on you! LoL

Just kidding, I know you have moving stress right now.

ATTENTION ALL!!

I was lucky enough to attend the RAVE at Deepak's, who is a hell of a nice guy, and I am also the guy who had Lukasz attend the NJ Audiophile's meeting on Sunday.

Even though Deepak and others had three setups and tried very hard to have a variety systems with different Lampizator DAC's to listen to it might have been better served to have one system tried and true.
Also as is typical at a RAVE equipment that others bring gets swapped in and out. This can make it hard to have a base for comparison.

By chance one of the Metro NJ/NY Audio Clubs I belong too was having one of their monthly meetings the next day. I asked Lukasz if he would be interested in attending so he could introduce himself and his DAC to our members. I also told him there was a chance we might be able to hear his DSD DAC in the system at the meeting. He graciously accepted.

Now I must say that it was very hard to tell how well the DSD DAC or even the BIG SIX sounded because we had no real reference point at Deepak.

But at the NJ Audiophile meeting that would not be a problem. Not with a top EMM LABS DAC and Transport along with equipment matching the quality of the EMM LABS.

This was my first time at this members house and one of the few times I was blown away by the sound I heard at a members house. It was a real treat when Lukasz first had a chance to hear Father Richards system. You could see his EYES pop open and his jaw drop. He knew right away that if we could put his DSD DAC in for a demo it was a system that would tell if he has the goods. Father Richards system has been compared to ones costing $500,000+ in sound. I will not at this time describe the details of the system.

After several hours of listening to the system including DSD from SACD through the EMM LABS Father Richards was gracious enough in letting Lukasz put in his DSD DAC. I brought some DSD files that Lukasz could add to what he planed on playing.

But before I describe what happens next let me tell you that Lukasz gave us a brief description of his work on DSD and thoughts on Audio. He also spent time in awe while listening to music through the system before we inserted his DSD DAC.

It only took a few bars of music for EVERYONE in the room to be able to hear what Lukasz's DSD DAC could do for the playback of music. You could hear people all over the room surprised at how well both Lukasz's DSD DAC and DSD done right could sound. AWE STRUCK is not significant enough to describe it.

Even Lukasz said he did not know it could sound that great.

ALL felt it OUTCLASSED the EMM LABS.

I am intrigued by the Lampizator. As some of you know it takes A LOT to impress my enough to be a FANBOY and post my enthusiasm. AS of now I need to first try the Lampizator PCM/DSD DAC in my system or one other that I am very familiar with.

Until then I give Lukasz's DSD DAC a BIG almost FANBOY.

By the way, the NJ Audiophile Society is planning on hosting a meeting for Lukasz,s Lampizator PCM/DSD in Jan of 2014.

Lukasz was kind enough to lend me the GM70s and DSD DAC that was at the Rave.  I'm  :oops: since I have ZERO DSD music and no pc at the moment. I WILL resolve these issues by the weekend.  Looking fwd to commenting more when I compare it to my fav L6 PCM recordings :thumb:

Jason, it is still tentative for Jan. It might be Colonia NJ 07067. It might also be at another location and/or at a later date. It is all in a very early stage as we just started to work it out, seeing as we just meet Lukasz. But most likely it will be between 30-60 minutes of NYC by car.

Deepak. BOY did you MISS it. You would have been blown away. Hell ask Lukasz. He had this little smirk on after he heard Father Richards system because he knew it would at least do his DAC justice. After his DAC was played you could see the twinkle in his eye. I swear I think he thought he died and went to Heaven.

Berto, it was nice meeting you also. I would be happy to ah hmm lend you some DSD files to get you started and also help in making sure your pc is tweaked for optimum payback. PM. I would be more then happy to help in anyway I could.

Ther very best measuring tool. jtwrace uses Gedlee speakers and Mr Geddes is on record as saying that we dont measure the right things commonly, so it leads to bad design decisions. There are an infitity of parameters to measure. the trick is to understand which ones are IMPORTANT and most relevant to achieve a certain goal.

I would have thought by now that big box amp manufacturers who post vanishingly low distortion figures and sound awful would serve as a warning that there is far more to this than the limited specs we see referred to everywhere.

Title: Re: LampizatOr Rave
Post by: wisnon on 24 Oct 2013, 01:39 pm
Dr Geddes interview excerpt (very balanced aned nuanced comments):

LB: One of your areas of research concerns the psychoacoustics of distortion. Please first explain the various types of distortion, and the distinction between linear and non-linear distortion.
 
EG: According to the strict dictionary definition of distortion, any change in the waveform shape is distortion. This means that any change in the frequency response, which would distort the shape of a complex waveform, is distortion. Mere frequency response changes are called “linear” distortion because they act the same regardless of the signal level of the signal and no new frequency content is created.
 
On the other hand there is nonlinear distortion which does create new frequencies not present in the original signal and this type of distortion is level dependent. For example, clipping has no effect until the clipping limit is reached and then the signal gets distorted. A crossover nonlinearity has a large effect on a small signal but a small effect on a large signal. Linear distortion is well understood, and it is the most significant audible form of distortion, but nonlinear distortion has not been studied in any depth (probably because it is far more complex and hence difficult to study than linear distortion).
 
LB: What prompted you to study these phenomena?
 
EG: I had long realized that nonlinear distortion was a characteristic of the system and was not about the signal being used to test for it. THD and IMD are simply different ways of looking at the same problem – system nonlinearity – using different signals. They are not different “types” of distortion. I wanted to find a way to quantify the system’s nonlinearity in a signal-independent manner, and one that I could show was correlated with perception. (I have had my suspicions about THD and IMD for a long time.)
 
In the study that Lidia and I did we confirmed that THD and IMD were basically useless indictors of sound quality because the measured values for either of these metrics did not correlate with the perception of music played through the system.
 
LB: An issue that engenders a great deal of ill will in the high-end audio community is the role of measurements. On the one hand are those who feel that measurements are indispensable and tell the entire story, while on the other are those who believe that measurements are of limited utility, and that all that matters is “how it sounds.” One of your important findings is that the perception of nonlinear distortion does not correlate with commonly used metrics of distortion, thus apparently lending support to the latter group. However, a strong correlation was found with the “GedLee metric.” Please tell us more about this.
 
EG: I have always thought that if someone’s measurements do not “tell the whole story” then they are the wrong measurements. Technology has simply come too far to believe that “there are things that we cannot measure.” I have also never believed that all that matters is “how it sounds,” because this is such an unstable and personal opinion. Sound quality opinions can and will differ from person to person, system to system and most importantly even within the same person on different days (as I said before, I have personally witnessed this in well regarded “reviewers”). Personal preferences have such a low stability as to be an almost completely pointless thing to stake a claim to. “Hi-Fi” does not mean “pleasant” — it means “accurate”; accuracy, as opposed to preference, is absolutely quantifiable and extremely stable – as stable as I care to control in my lab from day to day or test to test (but in any case its uncertainty is easy to quantify and understand). Decisions based on accuracy are therefore much more likely to be valid than decisions based on “how it sounds.” I do not see how one could ever support a position that “preference” trumps “accuracy.” That’s simply taking a giant step backwards in the evolution of Hi-Fi.
 
I am not saying that measurements are infallible, and I don’t believe that measurements are likely to ever be 100% reliable, but that does not mean that we cannot obtain measurements that are far better than the unstable subjective opinions that are so often relied upon. One has to know what measures are important and to what degree of resolution we need to know the results to be meaningful. What I see most people do are either the wrong things or not accurate enough to “tell the story.” And there are some things that I think are crucial to sound quality that are not measured by anyone I know of (myself excluded) at the present time.
 
All too often audio measurements are taken as an all or nothing proposition – “they aren’t perfect or completely reliable so why take them? I know what I hear so why not just listen and evaluate?” It is necessary to understand the importance of what you are measuring in the final analysis and how any particular aberration enters into the whole. An aberration at 12 kHz is not the same as an aberration at 3 kHz. Good measurements are all about finding those things to measure that matter, focusing on those and optimizing the design for the important things at the sake of the lesser importance ones. It is not always easy to know how these tradeoffs are to be made and that is where psychoacoustics comes in. The measurements that I usually see done certainly do not tell the whole story, they tend to be woefully inadequate.
 
One other problem with “listening tests” is what many designers and researchers have come to know as “acclimation.” We know that listeners will get used to or acclimated to a particular sound signature and that this signature then gets imprinted on their expectation. Expectation is a powerful bias in perception, maybe too powerful. This expectation problem tends to stunt the growth of real improvements because they can be counter to expectation. Accurate reproduction can often make a favorite sound recording be perceived as less than the expectation. This is then put down as a “flaw,” which may not be the case. Once the masses become acclimated to a particular sound signature it can be very difficult to change them from this path. I find this all the time with my speakers. They don’t sound like other speakers, yet I can prove that they are objectively more accurate. Over time my customers and I have come to appreciate the open and transparent sound that accuracy provides. Now all other speakers sound colored and distorted. One could argue that we have all become “acclimated” to the sound signature of our loudspeakers, but at least this signature can objectively be shown to be free from significant sonic aberrations. If you are going to get acclimated to a particular sound, then it only makes sense to get acclimated to the most accurate one.
 
Our study of distortion showed not only that what was being measured was the wrong thing, but that if you added some psychoacoustics to the situation one could develop a measurement that did correlate with perception. This result is completely consistent with I have been saying here – if your measurements don’t work then fix them. But don’t claim that something “can’t be measured.” That’s just a cop-out to doing the real work of finding which measurements matter and which ones don’t.
 
LB: Is it currently possible to incorporate the GedLee metric into speaker design?
 
EG: Well it is and I do, but perhaps not in the way that you might think. I do not use this metric to measure my speakers, in fact I don’t measure nonlinear distortion in my speakers at all. Our research taught me that nonlinearity in a loudspeaker is not all that important and that’s how it was used in my speaker designs. The GedLee Metric was shown to be a better way to analyze nonlinear distortion. It uses the actual nonlinear transfer curve that is the root cause of nonlinear distortion instead of some symptom of this nonlinearity like THD. By weighting the orders of the nonlinear transfer function according to how our ear perceives them we were able to show a much higher degree of correlation to subjective perception that any of the traditional metrics such as THD. Basically, for a loudspeaker the GedLee Metric is most likely to be very low except for problems like “Rub and Buzz” which are very high order and quite perceptible.
 
Our studies indicated that distortion in a loudspeaker is not likely to be a major factor as long as the loudspeaker is operated within its design limits. This is because low orders of distortion (2nd, 3rd, etc.) are not highly audible because of masking. Loudspeakers can essentially only exhibit low orders of distortion because the higher orders require large accelerations, i.e. large forces. Loudspeakers do exhibit very large amounts of low order distortion but not high orders of distortion (6th, 7th, etc.) – as long as they are not overdriven or have design flaws like Rub and Buzz – but the low orders are simply not audible. Using a well-made driver within its design limits lets one completely ignore the issue of nonlinear distortion in a loudspeaker.
 
This is not true at all for electronics. Electronics can generate very high orders of nonlinearity such as crossover distortion or clipping. One must be very careful in electronics design to prevent these higher orders from occurring especially at low levels. The problem is that this problem is never evaluated for electronics (well certainly never shown) and I doubt that it is even tested very often. What they do show is THD as a function of level but fail to note if the low level result is for crossover distortion or noise. If it is crossover distortion (which is very high order at very low levels) then it is highly audible even at fractions of a percent. That’s the problem with THD, it just does not show what we need to know.

Several years back I developed a test for amplifiers that used a special signal and form of synchronous averaging to measure the nonlinearity of the amp well down below the amplifier’s noise floor. This test revealed significant differences in the amplifiers as the signal level was reduced into the noise floor (the THD as the signal level is raised is again not important because it is masked and “THD + noise” at low levels, as usually shown, could be all noise). These amps all had excellent “normal” specs, but under my test they were vastly different.
 
Again the lesson here is that if your tests don’t work then fix them. Don’t blame the philosophy and hide behind the dogma.

LB: High-end audio is characterized by products with unsubstantiated claims; examples include a wide variety of (typically very expensive) cables, cryo-treatments, resonators that attach to walls and ceilings, anti-resonance devices upon which gear sits, amongst others. While it is admittedly unfair to lump all these products together, what are your thoughts about them? Is it possible that they have subtle sonic properties that we simply have not yet measured?
 
EG: I cannot be convinced that in this day-and-age there is anything that we cannot measure. The question is what to measure and are we asking the right questions. Are we able to accurately quantify the question and the answers? My position is that if some manufacturer claims an improvement in some sonic property, subtle or not, then it is their obligation to measure this (even if they have to figure out how to do that) and show in a statistically significant way that it makes an audible difference. Otherwise, I just don’t pay much attention to it because it’s just an unsubstantiated opinion. There are so many things that can be measured that have been shown to make significant sonic differences that paying attention to ones that don’t is simply a waste of time and money.
 
A comprehensive set of data for all my speakers is shown on my website – far more comprehensive than one normally finds. I can show how every aspect of what is measured and displayed has been found to be sonically important. It can also be shown how the tests I do not do regularly, like THD or waterfalls, are not that sonically significant. Close attention is paid to those things that matter and not those things that don’t. This is why Geddes speakers are in a class by themselves as far as value goes. They may not be the best, but they are certainly not the most expensive either (nor the cheapest I suppose), but I do claim that they are the best bang-for-the-buck in their price range.
 
This is what has gotten lost in the High-end audio world – value. Why would someone want to pay for something, often a lot, that is not supported by scientific evidence of any kind? This just doesn’t make sense to me. Of course there are those who completely discount science and as such their beliefs are all they have to go on. It appears to me that the High-end market is going after this rather small and select group – those who don’t require proof for what they believe or purchase – and as such a premium is charged to this unique market for being so unique. But I don’t think that there is much future in that. Sure it exists, but it seems to me that it is shrinking.

I do too (I am an actuary) but I have never translated that to my audio hobby.


I started out on the same track (Actuarial math) but bailed early to business studies and investment analysis.

It really shouldn't matter to you one way or the other since you did not think it was NY RAVE and it was Manufacturer's RAVE.

Thx



     It was posted on the Rave thread on Audionervosa. be careful what you wish for. Manufactures go through expense and hurdles to come and demo their wares. Dealers as well.
     Most are interested in new stuff. A wonderful venue for all. Good food , company and new gear oh my. Back in the day when the Rave was in full swing many manufactures were members. Everyone got along and many got to hear components they would never experience. It was cool no politics just fun as it it should be. A bit clicky but still fun.

   Here we go again.The measurement crew again. Measurements are key to a solid design. No question. What to measure to achieve ones goal is still not there.
    Saying that at the end of the day the component is listened to. the perception of the outcome [ potential buyer } is the whole deal. OK we look at the specs and measurements and hope the Engineer knows his stuff and designs a circuit that meets his or her requirements. Great.
     When a component or speaker is added to an existing system the potential buyer must determine if the different component sounds good in the system at hand. That perception or subjective decision is key to sales. No likey no buyie.
      Can one by specs determine the outcome of the newly added component ? Do not know. With Engineering of stress on materials or failure of such say in car design is critical. Someone could die. In audio with so much subjection as to the sound desired the "sound" had is all that really matters. Well to me and my customers anyway.

Stop making assumptions.

I have been following the views of Dr G. for a long time and happen to agree with him about many things.

I only posted andexcerpt as I said at the start of the post and I got it from a link prominently displayed at the GedLee website.

Please deal with the content and not with me or my actions. I am not against you, just some of your recent actions that could have been more forthright. I dont dislike you at all, as I have seen you make great contributions in the past. I dont even mind you having contrary opinions, if they are well elaborated and defended.

Lukasz is a high-voltage power engineer and you act as if he is some kind of novice in the engineering world. That is not right or correct.

What Geddes is talking about is looking at the spectral harmonic distortion carefully, which is what a dbScope or AP does. Looking at THD alone is useless as it's just a number.

Also, just to be clear, Dr. Geddes isn't an electronics engineer.  I'm sure you know that though since you've read his papers and know his background.

Heard the Lamp Big 6 last night at Grant's house. It is very hard to say what piece of equipment was adding what to the sound, since he has newly refurbished speakers (Apogee Duetta Sig's), new amps (Tube Research GT200's), & a Dude preamp w/ Duelands. And yes it is still all breaking in, so I expect it to get better.

The sound was probably the most real I have heard things in a long time. Incredibly spacious and airy, dynamic and detailed, and very musical. To know for sure what the Lamp was adding to this I would have to replace it with a known CD player/DAC but I can say that it certainly belonged in this league and was doing nothing to detract from the great sound I was hearing.

Post by: Lissnr on 24 Oct 2013, 06:49 pm
I enjoyed last wknd's get together at Deepaks, as I had mentioned, ( thanks again for the wonderful hospitality!) and I especially enjoyed meeting Lukasz. From my 30+ year obsession with this hobby I have heard so many back/ forth discussions about measurements  vs listening and I think most agree that even great measurements do not insure great sound and how they can often have very little relation to great sound . As for great music producing equipment designers, these people have to know more about their craft than an intimate knowledge of circuits and electricity... To make an electronic device that actually "Serves the music" to the extent that the sound truly approaches "Believable" through an audio system is almost magical and a far far cry removed from the relatively simpler world of knowing "how to" build equipment with great specs and measures well... It rises to a level comparable to a great artist instilling the most elusive of ingredients into a component... Giving it that intangible "Soul" that must be present to conjure up the EMOTION of the music... Have you ever cried at the intensity of an opera's Diva or felt your heart fluttering or your smile erupting with the sweetness of a singer or felt the rush of glory flow out of a symphony??? These are things almost exclusively found only in live performances and to EVER be able to even remotely replicate them in an audio system is truly rare and NOT something that can simply be  "designed in" with measurements and formulas alone.
To find equipment that excels so well in their "assigned task" be it amp or pre- amp, DAC ,TT or whatever .. Not to mention how speakers  come in to play ( no pun intended) is the journey that is this hobby. And it is a journey...
Equipment with "Soul???" You betcha. I have never known one designer to hit that mark as perfectly as Lukasz Fikusz has with his Big 6 Dac. It is absolutely magical. Lifelike recreation of tangible space ? It's got it. Virtually "immersive" presence . But does it do all the audiophile checklists? Detail? Frequency extension? Imaging? Ya ya ya ya ??? Yes yes yes yes ... It does everything that live music sounds like and you'll never pick up your " checklist" once the music starts... It just sounds "Real" Period.
I feel very fortunate... Less than 6 months ago I never heard the name  "Lampizator" and the only associations I ever had with anything Polish was an ex-wife (who was 100% but born in the US)., my current wife ( who is 50%) and I like them for their sausages and some pretty decent vodka... Other than that: "nothin". But now? I was very very fortunate finding out about this "Lampizator stuff"... It has really changed the quality of music listening in my home. Earlier this week I managed to get in contact with Lukasz himself through a few of my audio buddies ( thanks Bertolucci and Gopher) who kept in touch while he was " stateside" and I convinced them all to come to my place for a listen. Fortunately Murphy's Law took a night off and everything was cooking pretty well ( break- ins of my Duelund cast caps in my amps were underway and not complete but still sounding damn good). It was a great night and i insisted Lukasz claim the sweet spot chair exclusively ( there's only one chair that works... I have TSW'S Apogee Duettas Sigs and they don't do "Bose's ' Music Everywhere' " they just do AWESOME in one chair and that's perfectly fine by me). After that first song I was honored when he turned to me [ with something of a 'quiet amazement' on his face (I know ... But it seemed like that!!!?!!) and he said to me " Congratulations, your system sounds like there are no individual components that can be described or discerned by themselves... It all simply becomes believable music ... I can't imagine getting any better than this" . He said it ( I wrote the words down later to remember his first reaction/ comments as I often do for those 'first timers' to my room). A few songs later his response was simply "I have goosebumps...".  Coming from anyone these comments are wonderful... Coming from the designer of the most profound piece of equipment in my system I was truly honored... Sorry, call
Me sentimental but this "hobby" we all share goes a lot deeper [ for me] than collecting coins or baseball cards, golf or bowling, travelling, dining, mountain climbing... Or Whatever your passions may be... We all have a connection with music or we wouldn't be doing this like we are and this was/ is a big deal, as you could all imagine. All I can say is cool stereos... Ones that Really " bring you there" are SO damn cool, they just are. Great hobby.., lots of great people too. Thanks to all and to Lukadz : thanks for all your outstanding talent exemplified in your creations.

Hey Lissnr - thanks for impromptu invite and to see Lukasz twice in two states within 2 days (Polish Power)... Nice to see berto & gopher as well...

Your system is beginning to sound like a true "transporter room"... a little more break-in & few minor tweaks and you're there, ready for transportation to music nirvana... next time, I want the "sweet spot"!

Cheers,

Hi Pete, Thanks for the accolades and all the helpful advice you've given me for so long... your "drop-by's" are always welcome and I know I can trust [your good ears] for some straightforward opinions. Looks like it's all finally starting to gel ...just a few hundred more hours on the Duelund Casts and some minor tweaking, as you said. I'm convinced the last two pieces of the puzzle completed the picture with the addition of the amazing topic-of-discussion above: The Lampizator Big 6 as well as the "Golden Goose" amps of my dreams the Tube Research Labs GT 200 Triode Mono Blocs (love those KT 150's!) (Thanks Paul)! 
Maybe one of those "last item little tweaks" might be swapping out my TWL American 8G power cords for your new "7"s? We should talk. Anyway, thanks buddy...as I said: you're always welcome for some time in "The seat". Best regards,

Duelunds do take a few hundred hours but the break in is VERY natural and still enjoyable IMO. I do not think Grant mentioned he is breaking in NEW transformers too which will take alot longer then any caps will.

Thanks Berto, I am remiss in not bringing that aspect of my system up... I was told by Paul W. ( the designer / builder of TRL gear)that he replaced all my transformers with new, even quieter, heavy duty units which will take a good three months of operation before settling in to sound their best and it hasn't been half of that yet. We will see. Thanks!

Lissnr, you lucky dog.  What a system!  Congrats.  I owned the Dude for many years along with TRL Samsons and more recently the ST-100 which Rob now owns.  His transformers take a LONG time to break in as do the caps.  You are in for a treat.  From all that I have read, it sounds like the Lampizator gear is of the same ilk with that large and organic, "breath of life" sound.  There is no substitute for it IMO. 

All the teeth gnashing about measurements is amusing and diversionary and may reflect some early memory loss for Jtwrace (http://www.audiocircle.com/index.php?topic=119555.0).  I am a little surprised that the facilitators of this site have not busted him for being a troll. 

Audio is a closed loop equation in which the central variable cannot and will not ever be quantified.  It is a hobby of the heart in its purest form.  We have all heard gear that measures well but makes leaves fall from the trees.  Why is that?  This is an old experiment but still apropos in this regards:  http://www.stereophile.com/features/203/  What else is there to say?  I will take point-to-point wiring, custom transformers, and tube circuits over chinese conveyor belt products that measure well.  If it makes your "inner engineer" happy, great.  Go for it.

  I agree, awesome post! ( you have an insightful  perspective and a great way with words). As for the TRL gear (Paul Weitzel) and the Lampizator gear ( our newest hero, Lukasz), the common bond both designer/builders share ... Or, to be more specific, the exceedingly rare combination of brilliance, imagination, dedication, patience ... and all the other ingredients necessary to produce such "soul-stirring" equipment, is a talent they were both blessed with... { And }which ultimately becomes OUR haven from life's hectic pace through the glorious music they replay.
  I don't know if I'll ever convince Paul to make a trip to the NY area someday... (Maybe he'll be here on business sometime?) but one more snapshot in my room with Paul next to me would certainly be the perfect "other bookend" to the one [ above] with Lukasz. Now, if I could only get us ALL [3] together?!
  Cool stuff guys. Happy Lissn'n!

Title: Re: LampizatOr Rave
Post by: Lissnr on 25 Oct 2013, 08:53 pm
OK yes, sorry for the inspirational rambling... Back to the Lampizator  equipment itself. As a brief L4G4 owner I quickly realized how "real" the sound had become with it substituted for my Bryston BDA 1 ( which I always felt was a 'no slouch, solid performer' ), in fact, I was pretty much ready to go for the BDA 2 before Berto brought this plain-faced lookin box with Lampizator written on it over to my place.That's when I was sold. Ordered one, took delivery soon thereafter... And knew I had found the "source" . Only when I started reading about the Big 6 (again, because i had glanced at the write ups but thought it might be too much)did I realize that if it was half what it claimed it was and ANY significant improvement over the L4 I'd be ecstatic.
  So I took the plunge. My noted differences were this: the L4 and Big 6 shared a similar house sound... Open, relaxed, natural , unforced... Excellent imaging, mids, very good extension ( and coherence) top to bottom... A keeper. No "need" to move on ... VERY enjoyable and a great value .
What did the Big 6 do better in my room? Just a noticeable step "more" in the above areas but only really noticeable when I literally A/B'd them both on the same night with exact same material closely timed from one to the other... Otherwise you would have to literally own and live with both before your easily noticed there differences EXCEPT for just a couple other things... The Big 6, in my room, completely... and I mean completely removed the wall from behind my speakers and made my already vanished speakers seem like a "shock to behold" when you opened your eyes during listening...the "believability factor" simply blew off the charts. Tangible presence and absolutely like like "You ARE There-ness" was simply uncanny. So, I can't "list" more adjectives... This is the only way I can describe it.
OK guys... That's my stick - to- topic "report". Hope it helps.

I'll soon be taking delivery of the G4 L4, but was wondering about transport. Has anyone compared an external converter (I have the Audiophilleo and Offramp 5 on the way) with the likes of a Lampizator transport? In my setup the Audiophilleo + Aqvox USB PSU has improved upon every transport I've had in house and as my Lampizator will have an i2s option, it seems running it through an Offramp Hynes Regulated is a sure bet. Then again, as the adage seems to go, I've never heard the Lampizator (transport)...
