Thanks for great review of this preamp, I wish I can share some more info of same preamp. I own this piece for more then ten years, and three years ago I decided to "upgrade" my preamp. What I did was that knowing it was 20 years old replaced all electrolitic capacitors in preamp signal chasis and completly swaped wires. I put inside all "Cardas" 17 gage. and all black gate capacitors. All this resulted in huge improvement. I wish you would be surprised as well. You would be able to compare it now with top of high-end players. Send me your email for some pictures.
