View Full Version : SB3 and/or Touch as preamp

2010-10-21, 09:09
I've been investigating buying a Tripath-based system and just had a chat with a helpful chap at Item Audio (UK). He admitted unfamiliarity with the SB products but suggested that as the Touch and SB3 have a volume control they could be used as preamps and that, in principle this should give a good result.

This had never occurred to me. Is it something people here do? Presume to try it out I should set the volume on the SB3 to zero and work up from there?

Views and experiences?

You'll see some discussion of the pros and cons and some useful links in this (old) thread.

Personally I don't use my SBs this way (but do have a receiver going direct to powered speakers which works really well.)

Yes, Volume on Zero/Off.

Its not really a pre-amp function because its only for the Touch/SB3 and no other devices. But the Touch or SB3 will drive an amp or powered speakers because it has variable line level out on the Analog RCAs.

I just put a small system together for one of my son's friends that is a Touch, Adcom GFA-555SE, and a pair of Vandersteen Model 2CE Signature II Speakers. The Touch is the volume control and drives the 555SE perfectly.

If this is going to be a premanant setup and you can only stand the volume so high, it will be in your amp and speakers best interest to use either fixed or variable attenuators.

Thank you both for these replies and the link. As I write the SB3 is feeding my Arcam power amp directly, and it sounds good. (But Caiman DAC as preamp is way better!)

Thanks again.
