Eastern Electric MiniMax....The Prequel
« on: 24 Dec 2003, 01:21 am »
I have long wanted to place some tubes in front of my VMPS speakers.

I have tried several SS Pre's including a Citation 17, an Integra P303, A Parasound, and currently a .5B Bryston.

I like "silence".  I like .00% or better distortion numbers and I like "real" sound and a lifelike soundstage. (is that too much to ask? :lol: )

I recently talked to Bill O'Connell at Eastern Electric and he gratiously has sent me the MiniMax unit which arrived today as I was installing a "cryo'ed" Hubbell wall outlet.

I had been listening earlier to D. Krall "live in Paris" with the Bryston in place.

The Reference System in Music Room One (shades of AS and Seacliff) is plain and simple.

Denon 2200 DVD<AudioQuest Jaguar w/DBS interconnect

Bryston .5B<AudioQuest Jaguar w/DBS interconnect

CineNova GRANDE<AudioQuest CV6 w/DBS speaker cable

VMPS 626R with FST

I also have a BPT L-9 PowerCord on the CineNova, and an AudioQuest NRG-1 Power Cord on the Denon 2200

I leave the system on 24/7 so no warm up is required.

I normally have a BPT BP1 for power conditioning, but it is out on loan as of 3 days ago.

I spent well over an hour listening to D. Krall and a few reference cuts before changing out to the Hubbel Outlet.  It sounded great.  Listening to this live album, the soundstage was full and clear, though not quite as "black" as with the BP1 in the system.

I generally focus on "East of the Sun and West of the Moon" and and a Joanie Mitchell tune called "A Case of You", as Reference Cuts.

While on my knees switching the Outlet, UPS delivered the MiniMax.

The box was very light.

I didn't open it but instead finished my installation and plugged everything back in and fired it all up.

WOW! :o  :o

I wish I knew how something like this (cryo'd Hubbell) can make such a difference, but it does.  Although the improvements were throughout the sonic fabric, the two things I noticed most were the fact that at the same volume level on the knob (12:00) it was defineatly "louder", and the BASS was "much" tighter, deeper and stronger.

It was so strong that I could "feel" the old pant leg just barely moving and the couch was letting me know it was feeling the impact too.

CRAP!!!!  :x

Now what further could the new Pre do to improve on this?

Well, I can't really tell you yet since it is just fresh out of the box and Bill said at 20 hours it should sound good.  At 40 hours better.... and at 100 it should be as good as it gets.

But I did plug it in and hooked everything up (actually the other way around)

I powered the CineNova up again and then powered on the MiniMax.

Cool.... :mrgreen:   It has a very clean look and a good looking blue light (LED) in the power switch.  The Knobs feel very tight and of high quality.

Now remember that I have just powered this thing up and the tubes are just begining to "glow".  The chassis is still very cool/cold "to the touch" from being on the UPS truck all day, so this is not the best time to listen to the thing.

But I did....

I won't rave on about how it blew the top off the system since my system was sounding incredibly good and tight, but I immediatly noticed "detail"!!!

Not nessesarily more detail, (since I wasn't A/B in yet) but I did notice much more detail than I was expecting.  Bass was about the same (maybe an ever so slight touch less) and midrange sounded clean and full.

So I cranked it up.  D. Krall at 92-95 db can be "very" sharp, and aggressive.  Well straight out of the box and not even warmed up, I still noticed these qualities, but they were different. (and I can't put my finger on it)

In any event, if I had to say that I noticed anything important, it might be the texture to the depth.  That is, I was picking up more of a 3-D depth with great "shape" to the sounds.

So, I decided that was enough and flipped off the CD and walked over to the Great feeling Volume control and turned it up to about 3:00.  Sure there was noise, but not much, and I bet when I get my BP1 back that much of that will burn off like morning fog, by noon.

And when I turned it back down all of the noise was gone by 2:00 on the volume dial.  Keep in mind I was hitting 92db with the dial at about 11:00, so I think it passed the noise level test.

So now it is playing in the other room while I pound away on these keys, and the music seems "slightly clearer" and has nice highs for what I call ORL (other room listening).

So let me get to the 20-40 hour mark and I do some good A/B comparisons with the Bryston whch is one of the cleanest SS pre's I have heard (it passes the noise test too, with flying colors)

I did a couple minutes at really reduced levels (65-75db) and found the bass and detail still there.  That's impressive.

But right now I am very impressed, that it can offer this type of sound, straight out of the box, not "burned in", and actually "cold".

If this was as good as it got, it would be a sweet little number.  If it gets better with a few hours on it (you know how good a stew, or caserole tastes better after it allows everything to 'blend"?) it will likely find a place in the Reference System.

But right now, only time (and burnin in) will tell. :D

More later.....

PS - I'll also say it is a very well built little number and looks like a very "high quality" peice.  Gold RCA's and very tactile pleasing movment to all the knobs and switches.

John,

And when you have tubes on the amp side...

Being the "Power Freak" I am, it might be some time before I can afford that.  250wpc Tube Monoblocs are a little exspenive.

I am looking forward to how your 40's sound with the Kora's though.  I know Kevin has raved about his and how great they sound.

Hey Dog.....(how hip is that?)

I just listened to Josh Roban and now the MM is warmed up (been on for 3 hours)

Although I didn't A/B with the Bryston and as I mentioned earlier I did change out the wall outlet, Josh's voice did seem to sound a bit more pure and less agressive.

I also did another Diana Krall run through of "A Case of You" and the reality of her voice which is always "stunning" is even more so, but again no A/B yet.

And the bass which I said might be slightly less, "was" flapping my pantleg on both Krall cuts.

Too early to get excited of course, but this certainly is doing a few of the things I was looking for.  :D

I'll be interested in hearing how you think it compares with the "larger buck $$) Magnum 99 as well as the Aragon you just got.

Should be fun.

Hey John, nicely done.. Give that baby some time to "COOK" :lol:  I've got about 150 to 200 hours on mine and it sounds great.. Lots of soundstage and even better detail. I have mine in front of the Solar HiFi Fusion H1 and they are a great combo(For my taste). If you really like the unit with the stock tubes(very good tubes by the way) you will really freak with some NOS tubes in it.. I also use a tube phone stage and the trio(MiniMax, Solar H1 & EAR 834P) work very well together. Have fun with the MiniMax. I will be curious to hear what you have to say after about 50 to 100 hours. Keep us posted..

Have a great Holiday.

Heck, I have 16 tubes in each mono bloc!!  

John, now you know why I use SS for my HT...

 But seriously, tubes will defintely change the sound - only you can decide if it is for better or worse.

Yes it is 32 tubes in total, but ONLY 16 are output tubes.

The other 16 are EL84 and 6922 tubes that will need changing around 10,000 hours or so.

The other good news is that the output tubes are 6AS7G triode tubes.  These tubes are 15-25 each so a total retubing isn't terrible.  

It is a price I am willing to pay for the wonderful and enchanting sound they produce.    :xmas:

Nice"prequil", John,

We are not on the same page with everything, but we sure are regarding the Mini, so far.

Right on! I'm into DK in a big way, also, but I know exactly what you mean regarding the recording - not the best digital sound engineering. A good tube implementation make such recordings more acceptable.

I think the stock tubes in the Mini are very good at providing the type of clear clean sound that you have described. If you can, try to roll some other flavors of 12au7. I like the vintage Telefunkens for their body and warmth withouth sacrifice of detail, but they are about $70 per pair.

I don't know if you have experience with tubed amps. If not, and you decide to venture into this realm, don't pay attention to the stereotype descriptions and criticisms. They can come in all flavors and varying degrees of tubiness and transparency. If you do decide to go there, your music will seem to take on a new breath of life that renders concerns about measurements and accuracy irrelevant.

Hey Guys,

Glad you are enjoying the mighty little MiniMax preamp from our friends Bill O'Connell and Alex Yeung (Mr. Eastern Electric).  I have ~300 hours on my preamp.  

Want to take it to another level - try some tube rolling.  Here is a NOS recipe provided by Nathan Loyer of Audio Revolutions/Eighth Nerve that I have been following with great results:

Quote
In the left most slot, I HIGHLY recommend the Tung-Sol 6x4.  In the middle slot, the Valvo E80CC, and in the right slot is where you
should experiment.  My favorite is the Raytheon 5814A with the
Square getter.  The Mullard 12au7 is incredible as well, a little
more neutral than the Raytheon I think.  The Tung-Sol and Valvo in
the left and right tubes have SMOKED everything else I have tried
though.


I just picked up some minty 1950 Valvo tubes for the third (right most) 12AU7 slot and can't wait to try them out.  Enjoy and happy holidays.

I just came across the Hong Kong Tube Audio Clubs web-site.  Turns out Alex Yeung the designer of the Eastern Electric MiniMax is a member and it appears from information posted that the MiniMax started out life initial as one of his DIY projects. :idea:

Here is a link to the website with lots of interesting information:

http://www.hktubeaudio.homestead.com/index2.html

Here is a link to come major comparisons of 12AU7 tubes the club did this spring:

http://www.hktubeaudio.homestead.com/files/Best_of_the_Best_12AU7.htm

I haven't rolled any of these suggestions in my MiniMax yet.
