Personal Preamp Evolution

I found the the threads on the amplifier evolution very intriguing,the speaker evolution thread as well .I am not sure if there is already a thread regarding preamps.Many of us failed to mention their preamps[myself included] in the amplifier thread.After all, it really is an amplifier per say.
1967...Dyna pas 2 from a kit
1974...Dayton wright spa
1975...Mark Levinson JC-2
1976...Audio Research SP-3
1977... Van Alistine mods on Sp-3a,removed tone controls etc
1981...Audio Research Sp-6a
1982... revised to sp-6b
1983...traded back to the Audio Research sp-3a and modded further
1976..Audio Research Sp-10,revised to 10b[still in use]
1990...MFA Luminescence B[still my reference]
1996...ARC sp-8 mk2,Cat SL1 signature MK2
2000...DIY line stage,tube rectified,6sn-7gt's for gain.
2002 to present...Supratek Syrah,

1977 - Apt Holman
1979 - PSE
1984 - Perreaux SA3
1985 - ACR SP 10II (still in use)
1998 - EAR 834L (still in use)
1986: Acoustat TNP
1987: Audio Research SP11 Mk II
1990: Jadis JPL/Vendetta SCP 2B
1992: Jadis JP80MC
2002: Jadis JP200/Lamm LP2

I've had numerous other preamps in the system from time to time while the JP80 was being repaired (Meitner PA6i, VAC Rennaissance, Innersound, Klyne, Lamm L2 and LL2), but somehow I've continued to stick with the Jadis products. The current combination works extraordinarily well together, and on the few records that are cut so low as to require more gain than the Lamm can give, the JP200 has a total of almost 100db gain (including the line stage) to remedy that problem.
Hafler DH101(modded)
Stax SRA-12S
Naim 42
Naim 32/HiCap
MFA Magus(modded) still in use.

I keep my gear for a long time. Heard a boatload of new and used preamps when working at the audio store.
Main system:

Quad preamp (#33?)
Audio Reasearch SP9 MkII
Audio Research SP14
Balanced Audio Technology VK30 (my current reference)
Lehmann Black Cube (do phono preamps count?)

Other preamps:

Threshold FET Ten (lasted one afternoon)
Lazurus Cascode (used as a phono stage for a short time)
Classe Thirty (in use in my office system)

I think preamps ought to contain tubes! Do yourself a favour and check out the BAT stuff. Best, Jeff
Thats easy

Pre section of Pioneer SA-9500-II

Next, who knows?
I'm sitting with four preamps in my room now.

Blue Circle BC21
Luminous Audio AXIOM
Antique Soundlabs T1 DT

No EVO here, just dinosaurs and homosapiens coexisting, and I won't say which is which.

GAS Therdra
Mark Levinson ML-1
ARC SP6B (loved it)
Conrad Johnson 5
ARC LS 25 mkl & ARC PH 3se
Belles (forget the model number, don't have it anymore), Transcendent GG, ARC LS-15, David Berning microzotl modified to act as a preamp, Eastern Electric Minimax, and (hopefully very soon) Tron COmet. Still have the Transcendent, Berning and Minimax.
1976 - Dynaco PAT-4: a great starter pre-amp (used initially just with a pair of Koss Pro 4AA headphones), but suffered from the "Dynaco hum".

1977 - Phase Linear 4000: one heck of a piece if gear for a college freshman! I scrimped and saved all summer for it....

1981 - Nikko (forget the model #)

1983 - Apt Holman Model One. A great piece of gear, one I wish I still had for old time's sake. Had a unique "fade" control from stereo L/R to Mono.

1985 - PS Audio 4.5, later upgraded to 4.6....still use this to this day as a phono pre-map. The "straight-wire" mode is outstanding. Had an unusually large outboard transformer for a pre-amp; perhaps Paul McGowan's early experimentation with power conditioning!

1998 - Combined 2-ch with Home Theater, briefly used a Rotel pre/pro, then bought the Acurus ACT-3.

2001 - No pre amp for a time; ran my Resolution Audio CD-55 direct to the power amp for critical listening.

2002 - Proceed AVP- a true high end pre/pro at last.

2003 - Upgraded to AVP2 status.

Prior to the DB Systems, it was all receivers and integrateds.
1. Preamp section of Panasonic Mini-Receiver (found in just about every dentist's office in the early 70s)
2. Preamp section of Pilot 25 wpc integrated solid state amp
3. Preamp section of Yamaha CR620 receiver
4. Nakamichi 620 Tuner/Preamp (Slanted panel with gigantic tuning dial...coolest looking piece of equipment ever)
5. Hafler DH101 kits - several bought, built, modified and sold.
6. conrad-johnson PV3 - bought, built and modified extensively (great sounding unit)
7. conrad-johnson PV2ar
8. Beard P505 - luscious
9. Spectral DMC10delta - wonderful
10. Wright Sound Lab WPL20 - supremo

All have been used primarily for use with phono sources. The last two have been oustanding in this regard. The last is equally facile with digital sources.

2000 Threshold NS-10 ($30 at pawn shop, blown power caps. $10.59 to fix. Great pre,especially when put on the lab power-supply.)
2003 Bryston BP25, 1.5 phono (ultra-quiet and better musicality than all the tubes I put it against YMMV. Not the last word in high-freq dynamics.)
2003 Spectral DMC30S (Oh yeah, baby! Dynamics,extention, mids...pretty much everything.)
2003 Using the built-in preamp on the 390S (Awesome with right cables...and nothing else to switch. Will take in other digital sources though.)
Belles DM Preamp, ANYTHING?
I started in 1974. Alphabetically:

Audio Research SP-3
Audio Research SP-4
Harman Kardon Citation 25
Heathkit AP-1800
McIntosh C28

I still have both the Audio Research units.
I was an integrated guy up till 2000. Since then:

2000: SimAudio P-3
2003(May): SimAudio P-5
2003 (October): Bent Audio NOH (Transformer passive - the proverbial "curly wire with attenuation")
