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.

Rotel 930
Micromega Minium
Sim I 5080
YBA Integre DT
Monarchy SM 70 with Bellini pre
PS Audio HCA-2 + Bellini
Quad 909 (CDP99 direct)
Cayin AT88
Linar 10 5.1ch - a keeper

Looking to add a 2ch tube amp to have best of both worlds:
VTL ST 150 or Manley Snapper or Cary CAD211/V12R or Jadis DA7. Preamp is McCormack Micro, a gem.
Getting to this thread late. My quest for that "Holy Grail" started back in 1979 when I purchased a 100 watt Hafler amp coupled with a NAD Preamp running that through Snell C's. Of course there was no Cd's so a turntable was used. From there is has been one amp after another. I did evolve early into tube when the Music Reference RM9 was first introduced in the early 80's. Got some Magnapans MGIII's the tubes couldn't handle the load so went to the Krell KMA 100's. I did not stay there long, I liked the panels so I bought Quads and whet back to tubes, this time an Audio Research SP10 preamp with a D125 amp. I went through the whole SP series of pre's (10,11,12, and 14). That is when I totally had had it with tubes, traded my whole system for a Meridian Digital system. Had that for several years but lost interest in the whole hobby and really did not listen to my stereo for much.

The bug struck again, I bought a Wheatfield tube headphone amp that sounded so much better than my big system, the quest again began. I remembered, so I thought, how good that Music Reference RM9 system sounded I again bought one and mated it to some Martin Logan SL3's. I moved from one amp to another within the Audio Research, and Cary line. In 2002 at the CES show I heard my first SET amp. I was blown away with the whole presentation, the best I had heard, even in a very poorly set up room. I bought Cary 2A3 amp mono blockds only to realize that now the speakers needed to replaced. I bought some SET friendly speakers, I went from the 2A3 amps right to the Cary 805c's, from there to Sophia 845 based amps. The 845 tube just did not seem to have the magic that the 2A3 tube had so I tried a pair of Welborne 300b amps. Used them for awhile. I was invited over to a guy's house that had an actively bi-amped SET system. I went straight home and turned my system on, nothing, total disappointment, now what? I now have an actively bi-amped system. An Art Audio Carissa running my mid-base and a 2A3 amp driving a pair of ribbon tweeters. An expensive journey for sure but rewarding. I can't so the search is over but I do know that I will be actively bi-amping for sometime to come.

I'm sure I left out some amps that were shoved in during this journey, it has been fun and am looking forward to the continued saga...................Bob
In my last post to this thread back in Oct. '02 I had moved to a bigger room and switched from a CJ MV-55 to a pair of VTL MB-185s. These were the only tubes left in my system after changing to solid-state pre and phono amps. Latest power amp switch this past summer was to a McCormack DNA-500, so no tubes left at all. Sonically I don't miss them with this amp; reliability wise I'm enjoying my newfound freedom from care and problems, which translates into more listening to music.

1. 1990. Proton AA-1150
This was a great little amp for college. Good sound, good looks, and impressive amounts of power.

2. 1992. Parasound HCA-2200
This was to be my main amp for a small home theater system in college (yes, I was ambitious and already saving my money for a LaserDisc player). This poor amp was a big dud. It hummed like a banshee, but on a very irregular basis. I did not discover this issue until it was too late to return it to the dealer. I wonder if I just had a lemon or if the Mk II fixed an issue with the Mk I.

3. 1993. NAD 208 THX
This was an awesome amp that I held onto for 13 years (I just recently sold it to a friend). This amp was quiet, clean, had lots of power, and never gave me any trouble.

4. 1994. NAD 2400 THX
I still have this amp, currently in use on a pair of subwoofers. I have also used this amp in various applications like surround speakers and a 2 channel office system. Like the 208, it's a quiet and trouble free amp. It prefers small speakers though.

5. 1999. Bryston 4B-ST
This amp is still in service in my home theater. You simply can't go wrong with a Bryston.

6. 2003. Bryston 14B-SST
This is a bruiser of an amp, currently used in my 2 channel bedroom system. It has ridiculous amounts of power and is the quietest amp I have owned (until ASR came along). It will soon be displaced to the home theater by an ASR Emitter I.

7. 2003. Bryston 6B-SST
Currently driving the front three channels of my home theater, this guy is the little brother to the 14B. No complaints here.

8. 2006. ASR Emitter I Exclusive
Currently waiting for Christmas to come a few days early. I'm not sure how to upgrade from here...
First 'real' amp was a Rotel RA 820. Then came a Mission Cyrus One, a NAD 317 with an Rotel RQ970 phono-pre, then came a self built Class A power amp/Musical Fidelity X-Pre, X-LPS and X-PSU combination. Then the Musical Fidelity's changed into an Aragon 24K pre, which eventually got company from a Threshold S/300 poweramp. Now I'm saving for a Threshold S/200 poweramp to bi-amp..........

THANK YOU Mr. Frank Van Alstine ...
1. Kenwood receiver - served me well (I thought at the time) for many years.
2. Opera Consonance a120 Hybrid Integrated - my first foray into hi-end. Thank you Mr. Stephen Harris (playhouseaudio.com) for your kind intro to hi-end sound. But I later decided I wanted more power for my large room, so ...
3. Van Alstine Fet Valve Ultra 550 - power, finesse, extension, and musicality. Color me done. Thank you Mr. Frank Van Alstine for the last amp I'll likely ever own.
I started in 1974 with a Pioneer SX-727 receiver. When I discovered the high end in '78, that was replaced by a GAS Son of Ampzilla, which was in turn upgraded around the mid-80s to a B&K ST-140, which I still have as my main power amp. I've recently added a cheap demo pair of Antique Sound Labs WAV 25DT monoblocks (with their matching preamp) just to see if I can recapture some of what I remember of the magic of tubes from back in the day. If that little experiment turns out successfully, I may look into a PrimaLuna Prologue 1 or 2 integrated.

My evolution began in 1969 with a GE portable record player, the headshell of which was frequently weighted with a penny to prevent skipping. Next came my initial foray into components: an EICO integrated (can't possibly remember model number--this was the 60's, after all) with about 20 watts per side. I built a Dynaco Stereo 120 to replace that. After the Dyna failed about 10 times, I replaced it with a Marantz 250, then a Crown 150. I ventured into dangerous waters with the purchase of a GAS Son of Ampzilla, of which three different units never worked properly. In frustration, I traded for a Luxman integrated. Once I had the means, I finally got a Threshold 400A, which I kept for almost 20 years. The next amp age began with an Aragon 8008BB, which was a very nice advance from the antiquated Threshold, but not nearly as good as the BAT VK-200 which replaced it, with Clayton M100's in between. Only one direction left to go, and that was BAT VK-120 monoblocks, which were wonderful in every respect. I couldn't afford the power needed to run them, however, so now I have the Channel Islands D200's. I am still not completely satisfied, so the evolution will continue as time and budget allow.

I sold the big Ayre earlier this year & wound up with a BAT VK-200 after trying a handful of amps, including tube monoblocks (which were very nice!). I actually sold my entire system and it wasn't because I was unhappy with the sound. The VK-200 is paired with a BAT pre and I have to say this system is quite enjoyable. I've purchased/acquired more CD's so far this year than the previous two, so I've been trying to make more time to listen than before. One thing I've learned over the years is that a good amp design, be it SS or tubes, is a good amp design & will give you quality sound. A bad amp will do the opposite, period.
Yamaha integrated years ago. Can't remember model number but I still have it. Stored it at home during my college days.

Small pocket cassette recorder during my college days (very poor at that time but constantly surrounded by live music!) No, I don't have that any longer.

Back to the Yamaha integrated for a number of years until I could pay off some of that college debt.

=== and then came a real job...and real money!!! ===

Rotel power amp for my start into higher end audio. Again, I can't recall the model number, but I still have it sitting around. I had this hooked up to a nice N.E.W. P3 tube preamp and it sounded fairly nice...for a while.

Proceed Amp 2 was the next venture into power amps. Sounded very nice connected to the P3 preamp. But I wanted more!

CJ SA250 Sonographe was next. Liked them alot and they were relatively inexpensive, so I bought 2 of them and biamped my system. Their "tube-like" sound wasn't cutting it for me, so I sold them...back to the Proceed for a while. Then...

I've always wanted an all tube setup, so I debated between the Cary Rocket 88s and the AES AE-25 Superamp that I'd been reading about for some time. I found a pair of Superamp Monoblocks and took the plunge.

Now I have the all tube system that I've wanted for a while. My phono preamp is also tubes and I'm liking it alot. I may have to go for a tube CD player at some time.

I'm still surrounded by some great live music (professional musician) and am cursed by wanting to have my system sound like live music. Is there a system out there that will do that? I'd like to know...but I'm sure I couldn't afford it if it exists.
well this goes way back, first was a eltravoice receiver back in the 60s, next came a marantz model 30 integrated, then a model 250 using the 30 as a pre, then in the 80s a kenwood basic power amp, i got into surround sound and got a rotel 1075 which i lost to katrina, i started over again with a nuforce ref 9 and just had it upgraded to SE status, glad i got the nuforce gear they are super fine amps top to bottom,
Started solid, ending in tubes I guess..

Update to my system last month.... Still loving the Eico HF87 but have replaced the old Heathkit Preamp with a Decware SE84CSP. Wow! How cool is this! The sound just jumps out at me and images like crazy! I'm now in heaven.

Yaaaaa
Pretty impressive lists. Anyone know which member has one of the most impressive lists? I've not had a chance to go through all 8 pages.
It'll take me a few more yrs yet to post a list. I'm just starting. :-(
1. Kenwood receiver (100 wpc, baby cakes)
2. Opera Audio Consonance a120 Hybrid Integrated (sweet)
3. Van Alstine Ultra 550 (hybrid, pure music)

I have no plans on replacing the 550, unless I somehow, unexpectedly, acquire a load of cash, or my wife leaves me for some young, flat-bellied pool boy. I might then want to try a pair of ASL Hurricane 200's. Otherwise, I think I'll be happy with the 550 for the duration.

That is interesting because that is about how I started. (GFA-555 - I listened to this one level matched in a blind test with GFA-545 and the 555 sounded better - a little less grain.) Then got the Rotel which I liked more, and now am looking at a used Counterpoint.
