Personal Preamp Evolution

1980 Audible Illusions mini-mite
1982 Audible Illusions (new model of what was really the mini-mite)
1983 Yamaha C2
1984 PS Audio (concurrent with C2 and tubed pres)
1985 Superphon (ditto)
1989 Forte (Great harmonics, detail filter)
1992 Van Alstine Pas 4
1999 Onkyo P-304 (ridiculously good for the money, got it new for $129...MSR was $600)
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
SAE Mk XXX (I actually had 2 of these)
SAE Mk 1B
Yamaha C-85

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")

Not much here, since the mid 80's I've had the following:

Luxman C-120A
Acoustat TNP
Music Reference RM-5 (classic silver finish)
Dyna PAS 2
Music Reference RM-5 mk II (got the RM5 upgraded)
Dyna PAS 3
Hegeman Hapi 2
Superphon Revelation Basic Dual Mono

Others Auditioned:  Crown Straightline One, PS Audio IVH, PS Audio 4.6, Moscode Minuet, Audio Research SP8

For a long time, I've had int amps or tube amps with volume controls and used a small source selector box, so it was more of a straight wire with gain.  It's been 10-15 years since I had a preamp in my system and I miss having one :)

Currently using a Tandberg TIA-3012 integrated amp
