I bought my CSP2 last year and have enjoyed it a lot. I use it mostly as a preamplifier, and it takes DECWARE'S TABOO amplifier to a new level. The Von Schweikert speakers disappear and you might think I have floor standers in here. Those little screws that increase the voltage that the poster immediately above referred to are useful to "dial in" the sound you prefer.
As for tubes, I am using a Mullard PCC88 in front, some Russian 6N1P's in back with an RCA 5U4GB rectifier.
In the Taboo I am using a Mullard CV4024 (12AT7) in front, with Sylvania 6BQ5's in back and an RCA 5U4GB rectifier.
I totally agree with Skylab's comments at the beginning of this thread regarding the CSP2 as a headphone amplifier.
I have spoken to Steve Deckert many times and he never seems to be in a hurry to end the call. What a nice, knowledgeable man.
No, it has nothing to do with setting bias. It truly sets the gain of the input, so that you can account for source inputs of various levels. It's a nice feature.
I have continues to enjoy the CSP-2 more and more. It is a very fine amplifier, and with SinglePower amps not being readily available, it is the tube amp I most recommend in the $1000 and under price class.
Nice review Skylab! I have my eye on one of these. Trying to decide whether to buy a used one that's an older CSP chassis upgraded to CSP2 that would need to have headphone jack added or if I should just buy new from Steve.
The CSP-2 is really a nice amp. I recently ordered a different wood base for mine - will post some pics soon - looks even nicer. Also got some NOS Mullard tubes to use as well, now that the CSP-2 is in daily use
