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.
tireguy
1992 Arcam Alpha 2
1992 Arcam Delta 90.2 (needed something bigger than the alpha!)
1998 Naim Nait 3 (to replace the stolen! arcam delta)
2014 Rogue Sphinx.
ca. 1981: Panasonic console
ca. 1991: Kenwood receiver
ca. 1997: Carver TFM-35x
2013: used Forte 1a
2013: Pass Labs x250.5
2014: added a used Pass Aleph 5 to the rotation. Still have the x250.5 as primary
Pioneer SX-650 (1977)
Nakamichi TA2A (1989)
Rotel RSX-1055 (2004)
Arcam AVR350 (2006)
Odyssey Khartago (2009)
Pass Labs XA30.5 (2010)
Plinius SA103 (2012)
QuickSilver V4 monos (2013)
Lamm ML1 monos (2014)
If we start at the beginning I had a Pioneer SX-450 receiver (1977) which continued to be in use until a few years ago when a relative I gave it to put it out for collection. It still worked.

In 1985 I bought an Akai 45 wpc receiver. No recall of the model number- it was a forgettable amp was bought solely on specs vs cost. The Pioneer sounded better.

Around 1989 I bought an Adom GFA 545, 100 wpc. It was solid but a bit cold/hard. Their smaller power amp sounded better.

In 1990 I bought a pair of Magnepan MG2.6R speakers. The dealer urged me to sell the Adcom and get a more powerful amp. I traded the Adcom for a Bryston 4B.

I had the Bryston 10-11 years (during that time I bought a used AR solid state amp- might have been 75wpc? Didnt keep it long)

Sold the Bryton and bought a Proceed HPA-2. I also had an Ayre on loan for a bit but liked the Proceed better.

Kept the Proceed until 2003 or so and bought a CJ MV60SE

Kept the CJ until 2009, sold it and bought a Rogue Temest II Magnum. I thought it was better than the CJ (I was using a CJ LS172 preamp, which to this day remains the finest Pre I ever owned).

By summer of 2013 I decided my 10 year run of tubes was over. Sold the Rogue and am happily now with a Pass INT-150
Sony TA 515- circa 1978
Arcam FMJ 22 integrated circa 1998
Arcam FMJ P30 power amp - 1999
Bryson 4 BST - 2000
Bryson 14 BSST- 2001
Lyrita tube mono blocs 2004
Conrad Johnson LP 70S -2007
Wavac HE 833 V2- 2013
End of journey
In college, I scraped together some money for a Sherwood receiver (no idea what model--from the late 80s), driving Bose 401 speakers. I thought it sounded great at the time. Would love to compare that head to head with my current system. After that, my amp progression was:

Denon receiver (again, no idea what model)
Carver AV-705
Sunfire Cinema Grand (still use that one for my HT system)
Bel Canto Ref 500m monoblocks
Primaluna Dialogue Premium

And while I do like the Primaluna lot, I think the amp journey will continue over time.
Hmmm...

Updating further. After 10 years with the Lamms, when I moved to a new home with a much smaller listening room I decided to downsize (principally in the number of pieces) my system. I sold the Lamms and replaced them with a single stereo amp, the VAC Phi 200. Still keeps me nice and toasty on cold days, but now there's only one 90-pound amp to lug around instead of two of them. And there is no drop-off at all in the quality of sound; a truly wonderful amplifier that serves the music well.
My first amp was an integrated, Sansui AU9900

Then I added a Carver M1.5t

Followed by a pair of B&K M200 Sonata

Changed my speakers and subsequently changed the amp out to a VTL Stereo 50/50... Great sounding amp when it worked. Picked up a B&K 2140 as a back up.

Bought an Anthem Amp 1, one of my favorite amps ever, wish I didn't sell it. Changed speakers again.... needed more power.

I put the 2140 back in the system for a while and bought a brand new McCormack DNA 125 a few years ago that I still use.

It's a great amp, I think it would cost considerably more to better it than I'm willing to spend right now.

I think my next amp is going to be a Conrad Johnson Classic 60......

So far my favorites are the outlaw, behringer, mac, exposure and mac. But i liked them all except the mf.
I'd like to say a few words about my latest amp, as it is somewhat off the beaten path. This summer I picked up a vintage GAS Son of Ampzilla. Part of the decision to go with this unit was that Mike Bettinger, who runs GAS Audio, is located nearby. Without going into all the details, not only was it completely reworked but I also opted for the J-FET upgrade.

Funny how this is the newest amp I have yet may be the oldest separate I've owned-depending on year of manufacture.

Color me done ... the last amp I'll likely ever own ...
Ha! What a maroon! NOW I have the last amp I'll ever own ... NOT! At least I hope not, even though I love my current amps. So, to update my list:
1. Kenwood receiver.
2. Opera Consonance a120 Hybrid Integrated.
3. Van Alstine Fet Valve Ultra 550.
4. Audio Mirror 45 Watt SET monoblocks.
Wow this thread has been going on for over a decade. Time to upgrade my old response, slightly.

1972: Realistic STA-14

1979: Advent 300 w/ mods
2001: McCormack DNA-0.5DLX
2002: McCormack DNA-0.5DLX SMc Rev C
2006: McCormack DNA-0.5DLX SMC Rev "B+ Gold"
This amp still measures up fine,no upgradeitis any time soon.
Sansui AU-555 1970 - 1982
NAD 3150 1982-1985
B&K ST-140 1985-2010 one of the best/$

to my other amps I need to add:

Rogue 180's
McIntosh MC275's
Cary Audio CAD 500 MB's
Sanders Magtech (current)
Mark Levinson No. 23

FM Acoustics Res. Series FM 611

Onkyo A-9555

Bryston 4BSST

Hmm - really interesting question reflects lifestyle evolution:
Late 70s-early 80s:
Beomaster 4000 receiver
Braun LV1020s

Mid-80s:
PS Audio 200w
Adcom/NAD (various)
1988 cj MV75 bridged
90s:
1992 Krell KSA250
Downsized
1995 Classe 100
1998 Krell KST100
2012 VAC Renaissance 30/30

Given that I'm pushing 60 and that my life is very stable AND that I was really happy with the KST100 for 14 years - I think the VAC may be with me for a long time.
