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.

1) Crown D150
2) Hitachi MA 7500 (early Mosfet)
3) Michaelson Austin TVA-1 (sadly died may years ago)
4) Yamaha MX800
5) Adcom GFA-535II
6) Rotel 960BX
Current - Threshold Stasis 3 breathed on by John Hillig of Musical Design, Rotel 980BX stock.
The below list covers a main system in the basement and a bedroom system.

Started with a Fisher Receiver.

I started out with a technics integrated back in 1980, when I was stationed in okinawa japan, got a hold of sansui AUD-11 integrated which is still revered today and a yamaha M-80 amp, another sought after vintage.
Today, I have a combination of carver TFM amps, TFM 753, tfm 45, tfm 35, two tfm 500x, two 1.5t,m-400t,an emotiva xpa-5, sunfire theater grand, carver c-16, c-5 preamps, carver c 4000t preamp, emotiva usp-1 preamp, B&K pro 10 preamp. sunfire TGR 401 ht receiver and a pioneer sc 37 ht receiver. paxhton integrated tube amp,
Marantz 1060
Harman Kardon Citation 12
Crown D150
Ampzilla
Vsp labs Gold
Classe CA-2100
In order of acquisition - I often had more than one amp on hand:

NAD 3020 / B&K 102 / Quicksilver 8417 / Pass Aleph 3 / Pass Aleph 2 / CAT JL2 / Quicksilver V4 / First Watt Aleph J / Pass XA30.5 /Music Reference RM 9 Special Edition / Atma-sphere M60 / Music Refererene RM 10 MKII

Still own the last two.
I started reading Stereophile back in the late 80s, when I couldn't afford the good stuff. My first amp was an Adcom GFA-545, followed by a Parasound HCA-800. Next was a B&K ST-202. Lastly, I'm enjoying a Bedini 150 MkII I recently aquired off ebay for $350. I'm pairing it with an old Lazarus Cascade Basic preamp and love the combo! I still can't afford the good stuff, but ebay makes it easier to afford the used stuff.
Like many people here I started reading about high end audio gear before ever owning any. My uncle subscribed to Stereo Times, Stereo Review, and Audiophile and passed them to me when I was 14....and I devoured these magazines and dreampt of owning hi end gear one day.

My parents gave me a Fischer receiver from the late 1960s as a teen, and I recall it sounding amazing (Fischer?!?) Since that was over 20 years ago...I can't accurately remember how it compared to newer gear...but I'll never forget it. It was so clear. But I only thought of Fischer as cheap gear, and I eventually sold it real cheap. Now I don't care about anything regarding audio gear except how it sounds to me. Period.

I remember reading rave reviews of the Yamaha M-80 Power Amp as a teen and bought one in my early 20s. Coupled with a HK preamp, it was very nice at the time, but it didn't live up to its rave reviews....or that old Fischer.

At 25 I bought an entire used system that blew me away. It included a B&K ST 2020 power amp with a Conrad Johnson PV 8 preamp (with B&W speakers, Klipsch dual 15" powered sub, and other treats). I consider that to be my first 'good' stereo system. That was the first time I heard soundstaging in my home. I kept that setup for a few years, needed money, and sold the BK and CJ....and listened to garbage for years. I eventually forgot the MAGIC that a good stereo adds to LIFE.

In 2006 I got a bonus at work on a whim one Saturday I bought a Musical Fidelity A3 integrated amp. I WAS VERY PLEASED. The magic was back, in a big way. I could live with that litle amp now and be very happy if I had to.

I liked it so much I traded it for an A3cr power amp (which I like just as much as my friend's Nu-Vista integrated) and ran it with no preamp. I bought a Jolida JD 700 tube cd player (it does play dvds too which I know is audiophile blasphemy, but I prefered it to the JD 100, and I trust what I HEAR now). The JD 700 has a volume control, and it sounded so good to me (utterly transparent) that I thought using any preamp would be a step backward. I tried a older CJs and Classe', but preferred no preamp. It's that nice.

Three weeks ago I got another bonus at work and decided to get a preamp, thinking that even if the system didn't improve, it was practical. After debating it, (I considered selling the MF and buying a nice $2,000 integrated, either a Jolida tube or whatever) I bought the Jolida Fusion preamp which just came out. It's simply a superb combination. I couldn't be happier. The only change I can forsee making in amps anytime soon is getting another A3cr and bi-amping it.

I apologize for rambling, but this was a fun trip down memory lane!
I started with a 25 watt Sansui in 1973 then a Fisher 100 watt reciever,SAE,Nakamichi 600 then Carver dual cubes and finally my favourite PS Audio 200c great power and build.
Asterisk for "why did I sell it"
These only make sense in the context of what speakers I had at the time.
Dyna ST 35
Dyna Pas 3 and MK III s *
Dyna Pat 4 and ST 120 (Big mistake)
Sherwood integrated
Hafler 101 and 110 into DH 200 with mods
Flame Linear 400 (another mistake)
NAD 1020*
YBA Integre DT *
Meridian amp ? model
Krell 7B and KS 80 (to drive 'stats)
Threshold
Pass Kit
Audio Note 300B
Audioquest EL34 *
Conrad Johnson PV 11 with whatever 60 watt amp they were making
Jeff Rowland Concentra 2 *
Saunders MK 1 (to drive another 'stat)*
Tact S2150
Leben CS 300*
Marantz receiver mid '70's, Bryston 2B a short time later and Hafler 9180 ever since 1995. I regret ever letting go of the Marantz. At that time in audio history Marantz owned a lot of the market in it's niche. The Bryston had too little low end as it was 50W, but I liked it otherwise. The Hafler 9180 is a GEM of a performer. Never fatiguing. Never had one problem with it or any other of my amps for that metter. Rockford Fosgate is holding on the the Hafler name and patents and will not re-start the line. I have asked. If I have to ever replace the Hafler (will try to get it fixed first) I will stay with MOSFETS and go with the B and K 200.2. A MOSFET higher watt/current amp running in Class A at low listening levels. Want one NOW but $1600 is too much at this point in time.
Sony receiver

I've had the 334 for a little over a decade and aside from Pass Labs haven't heard much that makes me want to upgrade.

Of note is I do NOT like the Levinson sound since the move to the West Coast.

Here's my amp/int amp/rec'r journey from 1984 to 2012:

1. yamaha M50, crown straight line 1 preamp
2. Sansui AU717
3. NAD 2155, Luxman preamp, Acoustat TNP pre
4. B&K ST140, Acoustat, TNP pre, Music reference RM5 mkII pre & dyna PAS 2
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
18. Custom KT66 SE int (from ebay)
19. Onix OA-21s
20. ads A-2
21. JVC 80 watt class A int.
22. Musical Fidelity B1
23. Kailin 6bq5 int
24. Rawsonte Brick gainclones, Superphon Rev. Basic Dual Mono preamp
25. Audio Space Mini-Galaxy II
26. John Ecklund PP6bg6 triode - moded
27. Tandberg 3030 receiver

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

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)
Pass X-150
Quicksilver V-4
ARC VS-115
Joule VZN 160 MKlll Grand Marquis
Joule VZN 160 MKV Grand Marquis Musicwood

Spectron lll Mk2 (owned for 1 week) reinstalled the Joules

The Joule amps sound is so to my liking I think they will be difficult and most likely expensive to replace.
I had the Denon PMA 2000 AE (great entry level integrated, I used it with the same B&W 803D I have today and they sounded good!), now I have the Luxman 509u and I don't find any reason to change it!
Adcom 555 mono blocks
Bryston 4Bst
Bryston 6Bsst
Krell MDA 500's
Krell FPB 700cx
Krell FPB 750mcx
Late 80s: Tecnics class AA integrated, good loud amp for college
90s - 00s: Yamaha recievers, Arcam integrated and a Linn Classik that I still have in my bedroom
Late 00s: Tried the Dared 6 channel tube hybrid, wish it had a bigger footprint with better speaker wire connections and more inputs
Present: Audio Refinement Multi5 with a Pre5, which sounds great and beat out a Rogue Cronus Magnum that I had for a month and returned.

I might try consolidating down to the Audio Refinement Complete Alpha integrated since I am only 2 channel. How much punch, soundstage, etc would I lose doing this? Or anyone have an AR Multi2 or 3 in black that wants to trade?
My first love some thirty years ago, a Pioneer SX-525 receiver, held in my lap all the ninety mile way home. A Yamaha CR 1040 receiver. NAD then Carver Cube with the later addition of Carver TFM 15 amp. Acurus, my first "high end" the ACT Five. Which lead to my first tube integrated amp the SQ-88 by Quest for Sound. Tubes are indeed sweet. My best so far and dream come true, a McIntosh MA 6600. And just because a Marantz PM 8004. All have been a true joy. I love this stuff.
Well, I'm discovering this forum a little late but here is my "amp evolution":

1987: NAD 7220PE Receiver(my first component system which also consisted of a Dual 505-2 turntable and Boston Acoustics A40 speakers)

1999: NAD C740 Receiver. Bump up in power and sound quality. At this point also had NAD 502 CD Player and 614 Dual cassette deck)

2012: Rega Brio-R. By far the best bump-up in sound quality. Much more depth, detail and clarity with the Rega. But note this is also coupled with a prior upgrade to the Rega Apollo CD player and Rega P2 turntable (bias-2 cartridge). The Brio-R is bringing alive all of the detail that my P2 and Apollo is capturing.
really digging mcintosh. been through a couple of systems for my studio and by far the sound is consistently clean at the loudest output. cant complain with that when youre in the rock business.
1. Kenwood Receiver (early 90s)
2. Magnum (British made audio company that is now out of business)
3. Pioneer Elite Receiver
4. NAD Stereo Power Amp
5. Jeff Rowland mono amps
6. McIntosh 5100 Integrated
7. McIntosh 2105
8. Jolida 502P (Tube)
9. Jolida 1000P (Tube)
10. Bob Carver Cherry 180M Tube Monoblocks
Of course I am sure I forgot some.
Pioneer ~20W integrated - 1977
JSH pre, Dynaco ST-60 - 1979
NAD 3020 integrated - 1983
...got the bug again 5 years ago...
Hafler DH-110/Apt Holman pre, Hafler DH-220 - 2007
Luxman L-505u - 2012

Now restoring a pair of Heathkit UA-1 monoblocks (12W EL84 PP) to go along with a pair of original Quad ESLs!

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

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.

This amp still measures up fine,no upgradeitis any time soon.
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.
