Personal amp evolution


Seeing the over night success of the speaker evolution thread, it may be interesting to see what type of amp(s) we have all run. Same deal as the other thread-we will sort of create a puzzle of our systems you'll have to visit multiple threads to put everything together!!! ;)
For me I started:
Adcom GFA-565 monoblocks
Rotel RB-990bx
Jeff Rowland Design Group Model 5
Balanced Audio Technology(BAT) VK-60

either a CAT JL2, BAT VK-75se or Tenor 75Wp on the horizon.

I posted in Nov 2017 how I picked up the Ayre VX-5 Twenty but I sold it the following July, so it didn't really work for me.  I then picked up a Magnus Audio MA-400, which has worked well with my current setup.  I'm in the process of selling my speakers so I can move to bigger full range speakers and eliminate the JL sub, which was similar to a system I had 15 years ago.

To many to name, but journey has ended with a Toolshed Transcendence 300b Amp. Absolutely gorgeous looking but even better sounding. Matt is a master builder.
Very nice freediver especially when you made the move to tubes.  I’m still playing around making changes like sampling different flavors of ice cream.  I listed the preamps used with the amps as I believe it gives more useful information.  I’m downsizing soon back to an integrated and one less box soon.  But to update, here’s what I’ve had up to date:

I just noticed this thread was still active and I has the first reply, 16 years ago! I don't think I ever updated so here is my list of amps to date.

A truly heartening story.  Especially for someone who had Clayton M-100's for a 10 years and moved up to the M300s 18 months ago.  While I wasn't totally loyal (I have a Berning 270), I never sold the M100's until I went to the M300s.
At this point can't imagine owning other amplifiers.  On the other hand, I'm glad someone took the journey.  Kind of like having a car pass me way above the speed limit.  I'm always happy to have a runner <g>.  And you are right about Wilson.  He actually made a house call when I had a problem.  Welcome home.

Since my last post here, 8 years ago on 12-16-09, I traded up from the very good sounding Clayton M200 monos to their big brothers, the M300s. The list below picks things up from there.

Clayton M300: 300/600 wpc into 8/4 ohms, fully in Class A. There are so many things these amplifiers do well that I really need to cover them in a review. The main thing with Clayton amps is that they sound outstandingly real so you think less about electronics and more about the beauty and power of the music. Clayton amps provide much more power into Class A than the competition, and particularly at their price points. The M300s are about $17K.

Acoustic Imagery Atsah: 400 wpc. I replaced the Clayton M300s with these in a quest to have it all. The variety of NC1200 amps (i.e., Acoustic Imagery, Merrill, Mola-Mola, etc.) all offer a quiet, powerful, rich sound in a small, cool-running, package. They offered everything I wanted, except ultimately the sound. IMO, their sonic deficiency has to do with what I perceive as an absence of ambient information. I  do not know how that could actually be, but the sound reminds me of musicians individually playing in a studio rather than performers on a stage together. This is an inadequate explanation so, for those interested in understanding more completely what I ultimately could not live with, I recommend reading the review of the Mola-Mola Kaluga amps in Mono and Stereo linked below;

http://www.monoandstereo.com/2015/08/mola-mola-makua-and-kaluga-review.html

McCormack DNA-2 LAE with SMc Audio Platinum Upgrades: Steve did pretty much everything he could to upgrade this powerful (300/600 wpc into 8/4 ohms) stereo amplifier and it sounds very good indeed. It is clear, powerful and quiet, with a very nice tone. When I decided I couldn’t live with the Ncore sound, I took an opportunity on the somewhat rare LAE version of this amplifier and did not regret the result. I have owned several McCormack amps including a standard DNA-2 and the DNA-500. Of the four amplifiers listed in this update post, this is one of the two I still own.

Lamm M1.2 Reference: The biggest 110 wpc (into 8 or 4 ohms) I have ever heard. I previously owned the M1.1 and except for a somewhat dark sound, I completely enjoyed my time with them. These 1.2 Reference monos fixed the dark sound and kept all the other things I liked about the Lamm hybrid amps. The sound was full and tonally rich but with my speakers I ultimately found they did not offer quite the “slam” I was looking for and had a point where 110 wpc into 4 ohms was just not enough.  

Clayton M300: 300/600 wpc into 8/4 ohms, fully in Class A. Hey wait, did I not mention these at the top of this post? Sure did. After going through the three very good amps that replaced my previous M300s, I first tried to buy the original pair back and found that my buyer would not part with them. We still stay in touch to occasionally discuss things that work well with our Claytons. I finally purchased another pair used and sent them to Wilson Shen who fully upgraded them, as he did with my previous factory-purchased pair, and the result is spectacular. The somewhat large size and hot-running temperatures are small trade-offs for the outstanding sound I have achieved using these Class A amplifiers.  Wilson did not hold my temporary absence from Clayton ownership against me and in addition to being a wonderful manufacturer to work with, he is also a good friend.


I see this thread hasn't quite died out, so I'll add another update.  I enjoyed the rebuilt GAS for a good four years but in addition to simply wanting more volume, I wanted better speakers too, so I once again picked up another Ayre, the VX-5 Twenty.  This is my 4th different model Ayre over the last 16 years, so there's definitely something I like about these.
Ok. I'll play.

Really like the last 2, but if pushed, I’d take the Mac.
Regards to Zavato...
Sold my Pass X150.5 and regret it almost daily. Back to separates here as well, now using a McIntosh MC275 amp with an Audio Research LS3 pre. Pretty darn good, but the Pass, IMHO, beats pretty much everything else out there. I'll be getting back to Pass shortly - have you heard of Reno Hifi?
update
Ayre VX- R to Twenty ( Double Diamond )
also based on using REF 75 SE as a standin will be getting filters, etc to make the MC240 work in the main system.
Well I'm back to separates. Sold the Pass INT-150 and bought a Pass XP-10 pre and an X150.8 amp. Finest setup to get grave my abode

BTW- Pass recommends balanced cables between their amps & preamps. I tried an unbalanced cable first then balanced. Wow- if you are using Pass gear, run and get balanced. Even a $100 set of Mogami star quad will yield better results than a $1000 unbalanced IC
perreaux sx60 monoblocks - Good value amps to get me started.
plinius sb 300 - Great bass, but prefer tubes.
quicksilver v4 monoblocks - More musical than the sb 300 bit to romantic for me.
shindo haut brion - This has everything I ever want. Its visceral, dynamic, fast leading edge like a solidstate amp, but has all the great tube traits the way cymbals dissipate and the boogie factor is amazing. I also love how it doesn't smear over the detail and its ability to draw me into the music and emotionally connect to the performance rather than get distracted by sound.
A recent epiphany of sorts.

For many years I've been happy with a pair of MFA M120 B tube mono amps paired with dynamic speakers, Chapman T7's and Sonus Faber Liutos.

I recently acquired Magnepan MMG's and the tube amps just didn't cut it. I was unpleasantly surprised.

On a whim, I purchased a NAD C 272 amp. This modestly priced little amp is a game changer for me. Now I can only imagine what something like the Sanders, Odyssey Monos, or Wells would sound like powering the MMGs.

I am pairing the NAD with the wonderful MFA Luminescence pre amp.

I'm now using a Sandersound Magtech. It is fantastic with my Soundlab U-1s. I would suggest it as an alternative to the Parasound monos or even the most expensive tube amps. I found Sanders easy to work with and over 2 years the amps haven't hiccuped once.

I had it with the Wolcotts since I moved to an 1818 house and I don't believe there was enough juice in the living room to drive them....Hope the new owner is happy.

5. Dynaco ST70, Dyna PAS 3
6. McIntosh MC225, Music Reference pre
7. B&K EX442 Sonata - sounded almost exactly like the Paoli's), Music Ref pre
8. Paoli M60 monoblocks, Music Ref pre
9. cj MV50, Music Ref pre
10. Music Reference RM9, Music Ref pre
11. AMC CVT-3030
12. Mac 1900 Rec'r
13. Mitsubishe DA-R7 rec'r
14. Creek 5050 int.
15. Acurus A80, Hegeman Hapi2 pre
16. Early Korneff 6bq5 SE int.
17. John Ecklund PP6bg6 triode - moded Conn organ amp
18. Custom KT66 SE int (from ebay)
19. Onix OA-21s
20. ads A-2
21. JVC AX-55, 80 watt Special class A int.
22. Musical Fidelity B1
23. Kailin 6bq5 int

31. Fleawatt TDA7297 Zebrawood
32. Optonica SM-1515B int.
33. Onix OA-20/2

And the most memorable/best sounding: Mac MC225, Korneff, 6bg6, the Onix's, the B&K's, Paolis, the Fleawatt's, and the Ditton Elan

And the worst sounding/bigest disappointment: cj (just didn't mate up with the MR preamp & wish I had a PV5), Musical Fidelity B1, Kailin (fans just too darn loud), MAC1900 (great tuner but early SS harsh sounding amp)

I know this thread was for amp evolution, but I mad the mistake of posting my impressions about a newly acquired MA-1, and felt compelled to update whoever read it. Here goes:

The Meitner MA-1 has forced me to reconsider my former statement, "Although I like the new DAC, and it'll take some aural adjusting to fully engage the new sound, I could've lived with the dCS stack and been happy." The MA-1 is leagues beyond my previous dCS Purcell/Delius stack. The spatial information that I'm experiencing now is unprecedented in my system. The height, width, depth and weight of each item in the soundstage is the closest to "real" that I've had in any of my previous efforts. This feels goooood, and it's getting better each day.
Finally got a chance to listen to the new set up. There is far more presence with the Meitner MA-1 pulling decoding duty. The sweet spot seemed to grow - wider and deeper. Details are more apparent. This new realism allows me to see deeper into the musical event - and sometimes discover new sounds, accents or other treats that would otherwise remain hidden. It's a refreshing approach to the music that Ive been accustomed to listening to through the dCS Purcell/Delius stack. Although I like the new DAC, and it'll take some aural adjusting to fully engage the new sound, I could've lived with the dCS stack and been happy. What I liked about the dCS combo was the intimacy that was conveyed. This is just the first impression. The MA-1 was a dealer demo, and may take some additional breaking in. I'll continue to update you all as time progresses.
Thanks Thesaint519,

Yes, that makes sense...Lamm and Wilson go waay back, as they say! Congrats...must be a magic combination.
Lloydelee21,

I'm not sure the Lamms are any better than Brystons and/or Levinson, because I've never A/B'd them in my current system, although I suspect the Lamms are. I suspect so because of the glowing reviews and the audio community's overwhelming acceptance. But for the sake of full disclosure, having learned that the system is more than the sum of its parts, the system (and system synergy) is more than any one piece of equipment. What the Lamms do with my Sashas is more realistic, more full, well rounded, and weightier than the presentation of the other 2 systems, which included those respective amps.
Hi Thesaint519,

Thanks and understand. My own impressions of the 33H was that I could see from the first hearing why they are such venerable amps. Really effortless control and full-sound with a very nice balance.

The only part where I felt 'clearly audio design has advanced in the last 10-20 years' was in the treble where I felt compared with the latest and greatest (I suspect like your Lamms)...there seemed like a whisper of treble grain.

I am thinking of Gryphon, D'Agostino, even Boulder 2060...where I feel like those comparably powerful SS amps are even more refined, filigreed (without being dark, smoothed out) in the treble.

I have never heard Lamms...with my Wilson X1s...despite loving my Gryphon, many have told me about the wonderful sound one gets from their ML2 series with these speakers. I nearly went for a second hand pair of ML2.2s once, but without hearing (and knowing I would keep the X1s 'forever'...I was not confident to go for 18 watt monos). I felt the Gryphon at 160 watts pure Class A...I had more flexibility for today and tomorrow.

What about the Lamms makes them better to you than either the Bryston or Levinson? Most curious! Thanks.
Lloydelee21,

I all honesty, I really have no idea how the 14BSST2 compares to the Levinson 33Hs, because they were in two entirely different systems in two entirely different spaces. My apologies. The Bryston, however, was always crisp & clean in its presentation when it drove the Legacy Audio Focus speakers. The Levinsons, on the other hand, always presented a 3D soundstage with the warmth of a wool blanket when it drove the Revel Salons. But they both pale in comparison to the presence of the Lamm M1.2s.
Saint519,

Just curious...how did the Bryston 14BSST2 compare with the Levinson 33H monos (which I have auditioned briefly once)? And of course to your current Lamms? Thanks for any insight.
