I've built a system over the last year that sounds wonderful to my ear. I started out with an integrated amp and then switched to seperates after two months. I came down with the bug (upgraditis) and made a few changes along the way. I have auditioned amps and preamps in different configurations and I tend to favor the SS amp tube preamp sound I heard at one of the listening sessions. Now as I settle down and enjoy my equipment and accumulate music, I would like to hear others taste in gear. Do you own a tube amp and use a SS preamp, are you an all SS guy, do you love the "tube sound" and what does that mean? Let us know what type of gear you have in your set up.

Tube pre, SS (Class D amp) Listed in my signature. I love the sound. Very realistic. And very shaped by the tube pre... Thats my main system My others are SS all around and sound great too. In the end I prefer the tube pre/SS setup.

Thanks Mike,
One of the characteristics I noticed as I changed gear in my system was brightness. While playing a couple of CD's the vocal was harsh. I Noticed this on 2 tracks that I enjoy listening to. But as soon as the vocal kicked in I would turn the volume down, alow the passage to pass then turn the volume back up. Moving to the current tube preamp I have in my system added syrup around the edges. Softened the vocal, the 2 tracks I enjoy stand out because of this experience. This is the best example I have of how tubes "work" in a system. Or should I say how tubes work in my system?

Hi Kirk,
I have a high end SS system right now but I am also looking to address some of the hardness that I hear occasionally especially in the vocals. Frankly I suspect that in many cases the "source" of the problem may be in the recording itself --need to experiment on friends' tubed systems. Even if that's the case I'm willing to give up some accuracy for a more pleasing sound. I also plan to attack this via the pre-amp. Question: Why did you settle on the CJ CT5? Did you try other tubed pre-amps?
-Robert
Mike: I see that you went with the Supratek--not quite as well known. How did you come to chose this pre-amp?
-
Robert,
Before puchasing a preamp I auditioned Rogue, VTL and CJ. I ended up going with a VTL TL-2.5 tube pre. The VTL lived in my system for about one month. I loved the 2.5, but I felt like I could capture a bit more if I upgraded. So I looked around, listened to a Cary pre and I came across the CJ CT5 at one of my local shops (used). I took it home and listened to it in my system and I was and still am blown away. I settle on the CT5, because of the $ and once I listened to the CJ it was not moving out of my system for a while.

Long story short, No preamp (well I do have a tube pre that I use for SACD), solid state amp for lows, and tubes for the highs.
In my experience the draw to solid state is its "Accuracy" and "Neutrality" and of course the power and dynamics that pretty much only a solid state amp is capable of producing on most loudspeakers (more on that later). I have yet to hear any solid state amp that is anywhere close to accurate in the way it conveys music or the essence of what the artist is trying to convey. They can sound pretty darn good, but ultimately miss something very very important to sound reproduction.
In my opinion tubes are far more accurate and while they do add warmth to the sound I wouldn't say they are coloring the sound in the sense that something is being added that shouldn't be there. A well designed tube amp is capable of excellent transients and extended high frequency sound. And depending on the setup they are capable of amazing dynamics (and a lot better microdynamics than solid state)
Obviously no amp design is perfect and tubes have their weaknesses. First they kinda suck in the low bass/ mid bass domain. Others may disagree, but even megabuck tube amps have softish bass. And Solid State has it's various weaknesses. Such as recessed midband, hyper exaggerated treble and nasal qualities.
So what do I do? Active biamping using a TomS modified DCX fed with a digital feed from my CDP. I use a solid state amp (don't laugh it sounds amazing) a QSC professional "nightclub" style amp. for my RM40s for everything lower than 300 hz and The Bella Extreme 3205 (highly upgraded) tube amp for everything above that. This allows the tube amp to be freed up to do what it does best, liquid mids and top end. It also allows for amazing dynamics since it's power isn't being zapped to produce 30hz bass drum thumps. As for the bottom end? Gut pounding, tight, musical bass.
-
I tried biamping, with tubes on the top and SS on the bottom. I've since come to the conclusion that
(a) it is very difficult to balance out 2 different styles of amps without an active crossover
(b) the passive crossover point in my speakers, at about 3K, is too high. Most of the midrange and treble fundamentals are still being driven by the SS amp. A lower crossover point at about 150Hz would be about right IMO.
So I've gone back to a SS amp and my tube pre. The homogenous nature of one amp definitely sounds better to me, and the tube pre helps with the bloom and naturalness.
Of course, when I play vinyl the signal also runs through tubes and it sounds glorious.
-
Good SS is good, bad SS is bad, good tube is good and bad tube is bad. Moral of the story is that you can get good with any combination and you can get bad with any combination. I use them both goodly. :wink:

The biggest issue in your setup seems to be the passive crossover. biamping with a passive is sort of like not biamping at all. You will hear a difference, but if you're going to do it, just go active, that way you can play a bit with the crossover point a bit (just make sure you don't blow a tweeter doing it!)
A lower crossover point at about 150Hz would be about right IMO.
I have gone as high as 500-600 hz with a solid state and the tonality still sounds very tube like without any negatvie effects. That said I prefer a crossover point around 300-400 hz in my system.

I don't understand this. Why is biamping with a passive like not biamping at all? There may be some attenuation prior to the amplifier due to a passive crossover, but with a well designed passive crossover this can be small. Any insertion loss is likely to be largely irrelevant if you have enough gain in your system anyway. Importantly, the passive crossover still ensures there's nothing between each driver and its channel of amplification, and this should be where most of the advantage lies.
As for varying the crossover point a bit: you can build either passive or active crossovers with variable crossover points. Regardless of whether it's active or passive, the extra circuitry required to give you that flexibility will degrade the signal. It's not clear that it's worth the tradeoff to be able to play with your crossover point. Certainly, after you've done all of your experimentation to determine your optimal crossover point, you're only likely to improve performance by tearing out the part of the circuit that adjusts the crossover point.

Kirk,
Despite the flaws in reasoning...what has sounded best to me is a SS preamp and tube amp(s).
I listen mostly to vinyl and boosting very feeble signals seems best with solid state I've found. I've also found the best signal is the shortest.....particularly for feeble cartridge voltages. So, my preamp is a full featured with phono stage.
But, for amps I use (tube voltage-regulated) tube mono's. They are 'taut' sounding unlike many tube amps....so it gives me that bass control/sound like solid state with lushness and presence that only tubes seem to give off.
The 'flaw in reasoning' is that most engineers and alike will tell you that if tubes are to be used in a system....they best be at the preamp level so that the solid state amp is left to drive demanding loads like speakers best. But, I have found exactly the opposite (at least with my minimal load and minimal crossover speakers in a 14 x 16' room at barely medium decibels)
So, keep an open mind to the opposite of what you are now thinking. Many others have reached the same conclusion as I have and are in nirvana now :)

If I could design a speaker to be used specifically for biamping it would probably work out better than me trying to use my current speakers with an active crossover. I'm not trying to change the crossover point on these, and as a result I didn't get the full benefit of the tube amp in the mids and top end. A lower crossover point would have been needed and my speakers would not be able to support that. Plus the relative balance and power of each amp were drastically different and it is not easy to get that balance right at normal listening levels, nevertheless at all listening levels.
Unfortunately the tube amp I used, although very good, was not able to control the woofers on my speaker very well. It just wasn't a synergistic match in my case. I think you have to have speakers and amps that work well together for this to be valuable and I wasn't into changing my speakers to make this work (I like them just fine as is with my SS amp and tube pre).

Importantly, the passive crossover still ensures there's nothing between each driver and its channel of amplification, and this should be where most of the advantage lies.
It's different for a very important reason, it doesn't eliminate the passive crossover. Regardless of how well it's designed it is zapping the power from your amp. changing the impedence curve of your speakers, and adding a lot of coloration and phase shift (so will an active but to a far lesser degree). Passive biamping will improve the sound, don't get me wrong, but to say it's simply a difference involving attenuation nothing can be further from the truth.
An active crossover opens up a world of possibilities. Some (not all) allow for time alignment, selectable slopes (1st order, 2nd order, 3rd etc etc) as well as room bass EQing or any amount of room mode EQing or driver anomoly EQing. A few of these problems can be solved with a passive crossover, but why bother? You are adding components to the signal path and the more there is the more likelihood of dirtier sound.
As for varying the crossover point a bit: you can build either passive or active crossovers with variable crossover points. Regardless of whether it's active or passive, the extra circuitry required to give you that flexibility will degrade the signal. It's not clear that it's worth the tradeoff to be able to play with your crossover point.

Chad
Again the difference is what components you are adding to the signal path. A pot for crossover frequency variation is far from ideal. An active digital crossover will cause much less signal degradation than a passive component. Full active is just plain superior in every respect (other than ease of use and cost of course. :lol: )

Sorry for the double post, but I have this great article from TNT I've had for a while that is incredibly relevant to the whole passive/active discussion we are having (albeit somewhat off topic to the original post, it is relevant to the conversation!) :thumb: :thumb: :thumb:
http://www.tnt-audio.com/casse/active_speakers_intro1_e.html
As an editorial side note by yours truly, while important and unavoidable sometimes, passive crossovers have become a major selling point for a lot of manufacturers. Including some on this site. While I do have an appreciation for the virtues of a well designed passive crossover, I cringe at the idea that manufacturers like Wilson, YG accoustics, B&W, etc etc, get away with espousing the virtues of there cutting edge passive crossover. One manufacturer goes as far as to incase the entire crossover in epoxy so as to "prevent patent and design infringement" :roll: While I'm sure many talented designers with a tremendous knowledge/experience base poured the better part of months into the conception of such designs, IT'S STILL A PASSIVE CROSSOVER!!! Yes, I bet their passive sounds great, but it will not sound as good as a well designed active setup.

Thanks John,
I have auditioned the Parasound JC2 pre and Ayre's K-5x pre, both SS and both sound great in the system I listened to. If I were to veer towards a Solid State pre those two options are were I would start, because of there availablity to me and because I've heard them and enjoyed what I heard.

Better yet, go tubes for amplification and ss for your preamp. aa

Pez,
From a cursory glance, that article seems to argue the importance of using line level crossovers. But that doesn't mean that the crossover has to be active! You can have a perfectly good passive crossover at line level, and it will have the same sorts of virtues as an active crossover. The system you have is truly "active", in the sense that each driver is attached directly to an amplifier, without any passive devices in the way to mess around with the impedance. However, with the passive line level crossover, you don't need all the additional circuitry to generate gain. Nor do you need an additional (potentially noisy) power supply. In other words, the passive line level crossover is far simpler and (likely) far more transparent than any active crossover ever will be.
The problems to which the article refers are not related to the fact that the majority of crossovers are passive, but that they are placed between the amplifier and the driver.

The JC 2 is a very good preamp and I am seriously considering buying one after having an extended audition for the last month or so. Compared to my Plinius M8 (which is also excellent), the JC 2 has much better bass (especially in the lower registers) and is sound stage champ. It is close to the M8 in the highs and mid-range and both have all the functionality that I need in a dedicated 2 channel system.

Just curious, why?
I AM a Tube-o-Phile! So I consider tubes somewhere in the system essential. When it comes to preamps, I've heard very few SS pres not add a slight (sometimes not so slight) metallic haze to the sound and I have heard not a single one have the depth and 3D quality of a great tube pre. So for me, if you're going to go SS at all go with an SS amp but always use a tubed pre. Again, just my humble opinion.
-
Eric,
Did you hear that haze at my place? I don't, but maybe I am used to it. :-)
When you were over, I was using a ss preamp (Plinius M8).
George
-
Over the years, I've been all over the map - all tube, all ss, ss amp with tube pre, tube amp with ss pre. I always keep coming back to the same thing - SS amp with tube pre. It's the only combination that for my taste, gives me solid, tight, extended bottom end, plenty of speed, good control of speakers with odd loads, ability to drive innefficient speakers, great imaging, and a sweet midrange. Plus, it gives me the ability to tweak to my taste a little by rolling tubes without it costing a fortune buying matched quads or octets.
My second choice is all tube if done properly.
YMMV

agh makes sense. I miss understood your post

solid state for subwoofer amp, (or for bi-amp set-up, if x-over is ~300hz or lower), tubes everywhere else. re: x-overs, while i prefer active, passive is ok if between amps and preamp, not between amp and speakers...

I had an interesting experience at an audio shop in my area. The salesman was gracious and wanted to share the three systems he set up. One an integrated amp CD player Usher BE-718 then switched to Esoteric MG-10 system, a great starting point. We listened to a female vocal/acoustic/jazz CD he had on hand, it was a great demo. I became acquainted with the music as quickly as I could. We then moved to a McIntosh system all tube feeding Usher BE-20 just amazing I could hear the rounded edges, the liquid sound of the tubes was apparent to me. He then played the CD in an all Chord system Blue CD player, DAC, Pre and Chord amp partnered with B&W 802's. Wow, I was blown away by the soundstage not paying attention to the SS/tube difference. The interesting thing is he recommended we listen back through. In other words from the Chord gear back to the integrated system. That process made a difference in that I had a point of reference not going forward but traveling back through. The exercise was my first comparing tubes and SS side by side. So at the point he said "let's listen back through" I paid more attention to the systems and not the music. I became a more analytical listener. The experience taught me what I heard from tubes and SS and what to listen for in the future. Hopefully this will keep the juices flowing here.

No, George, your Plinius did not have that haze.

Are there any members who have gone from a Solid State preamp to a Tube preamp that can share their experience? My tube preamp quieted the sharp edges from my digital front end.
Kirk
-
It's not "quieting the edge" so to speak that edge is something solid state adds, it is prevalent in the sonic signature of many pieces of solid state equipment.
In my experience a lot of what people attribute to as "detail" in solid state is really an edginess that is a specific coloration that SS suffers from. Every piece of equipment ever made COLORS the sound accentuating certain tonal aspects, shifting phase/time coherence, adding distortion, noise etc etc. No type of device is exempt.
Now as for subjective comparison, yes I have owned and auditioned many different amps and preamps over the years and I prefer the tonal characteristics, transients, and over all presentation of tubes over the tonal and otherwise coloration introduced by Solid State. There is just no comparison.
A lot of cliches have arisen about Tubes that just aren't true... Well maybe sometimes they are, but if you have decent equipment they are not. Such as tubes can't do transients, tubes have a rolled off treble response. Not true in my experience.
-
Tubes rule :) I just wish there were more fully remote controlled tube preamps. My Mapletree 2a SE is great, but I'd love to be able to switch inputs or volume from my listening chair.
Preamps, in my opinion, have the least improvement on the system by switching from SS to tubes. The most important is the source, followed by the amps, and then the preamp is last. And if you can biamp (or triamp) and still use a SS amp on the bass, it's pretty close to an optimal solution.
-
I've always left tubes for small signal duties. There are plenty of tube amps that are great too but matching them up with speakers can be more difficult, especially with Single Ended Triodes.
All of audio is mixing and matching to get the results you want. No matter what you use your going to need to experiment and try different things to find exactly what fits your taste. If you don't want to be on a never-ending treadmill trying different equipment figure out your speakers and room first. That will dictate what you need to drive them. From there on out you can dial-in different gear upstream to fit your personal preference.
-
If you are gonna mix them up, conventional wisdom says tubed pre and SS for amp.
Me? I use tubes wherever possible. If I could put them in my turntable, I would!

No offense intended, but F@#% conventional wisdom, :cuss: I'm with you tubes all the way. (except for your bass/sub amp then go solid state. :thumb: )
-
hey kirk - my bel canto integrated has a solid state pre section and set amplification section...while this sounds backwards....the result is pure bliss :). there are several other combination integrated amps out there if you're not ready to spend the big bucks on separates.
i also had a lot of luck with a dehavilland tube pre and spectron ss (digital) amplifier.
oh, and if you're happy with your current pre/amp/speaker synergy...youo can always go with a tubed dac.

I have an SS/Digital amp pressed into service in my system at the moment (my tube amp is kaput). Ouch, the highs are fairly painful.

Tyson,
Do you also feel that a preamp is third in order of importance in a system? Or is it forth after speakers also? I read your post to say least improvement regarding SS to tubes.
The reason I ask is it is my humble opinion that a preamp is the 2nd most important piece of equipment in a system. Speakers first.
Kirk
-
Yes, speakers are the most important piece of equipment in the system. Then comes room treatments. Then comes the source, then the amps, then the preamp, then power conditioning,then wire, interconnects, power cords, isolation footers, etc....
-
huh, you put room treatment ahead of source? Are you high? I don't want to down play the importance of RT, but if you have a bad source no amount of foam padding is going to change that. :lol: Not to mention us hen pecked gentlemen (yourself included) do not get the luxury of room treatment so we're pretty screwed to begin with, your order makes it even worse!
The again I suppose a lot of that has to do with how bad your room is. If it's really echoey then it could potentially be the number one most important. :scratch:
-
That's why I enjoy this forum over others, most everyone is respectful. I agree to disagree. Speakers, treatments, preamp, front end, amp, cabling...
I share your love for tubes and will probably always have them incorporated in my system somewhere.
Here is a snap shot of my room and my treatments.

Wow that looks like a very well treated setup you've got there. That ceiling it seems like it presents it's own problems when it comes to placement etc.

Nice setup! Love how you've made the ho-hum treatments look very cool by the symmetry of the placement.

My next system change is upon me. I purchased a Mac Mini and will soon receive an Ayre QB-9 USB DAC. My concern as it relates to this thread is the "digital sound". I am very happy with the way my system currently sounds. I hope the addition of a solid state DAC doesn't increase the edge I was familiar with, in my system, prior to adding my current tube preamp. I am looking forward to the ease of storage and user interface, but I will have to see how the change sounds in my system. I have auditioned the DAC 3 times through 3 different pair of speakers and I love the way it sounds. Your thoughts please.

He is right - room treatment is more important.

Sorry George, you did miss "will soon receive an Ayre QB-9 USB DAC" SS DAC. "I hope the addition of a solid state DAC doesn't increase the edge" or increase the brightness of the SS DAC.
Currently I enjoy my entire setup, my Arcam is less bright that other CD players I have heard and the Arcam fits well along with my other equipment.
I hope that helps.

And if you've got a crappy room, you can have the best source in the world, and you're still going to hear more of the room than the source. IMO, the 2 biggest things impacting sound are the speakers and the room. Everything else is a matter of matching.

I misunderstood and thought you were comparing the Ayre USB DAC to a tubed DAC and not your Arcam.
FWIW, a friend who tried the Ayre thought it sounded more like a tubed DAC than a solid state DAC.
I hope this works out well and that you are happy.

Thanks George,
I have heard the DAC sounds "analog" or "tube like", too. From those trying to sell the unit. I auditioned the QB-9 and to my ear it sounded more open and airy when compared to the Ayre C-5xeMP which is Ayre's top shelf CD player. I am going to ask to take the Demo unit home for an over night test in my attic. I will post my impressions when I have them.
