Preamp suggestions for Thiel 3.6 & Bryston 4B-sst

Having owned several Bryston amps my pre amp of choice was an AR LS 15 with Infini caps.Together they yielded a distortion floor as low as any combination I've used.

Cables can help with warmth also. Good suggestion on the LS-15.

Hi Dbdog: I own all ARC gear (pre, phon, CD and amp) and love it!! I've tried several ARC pre-amps (SP-9, SP-16, SP-17 and Ref-3) and amps (VS 110 and VS 115). Don't know much about Bryston. Let me put something out there for you to think about. I also encourage others to weigh in too of course.

Rather than an ARC pre-amp, how about an ARC amp? I'm not sure whether the pre or the amp will contribute more to the type of "warm-tubey" sound you are looking for. If you want to think about the amp route, I suggest a VS 110. There was a VS 110 for sale on A'gon for a decent price, but I just checked and saw that it was sold. No surprise there. It's a great amp. Not to worry though because a VS 110 always comes up for sale from time to time.

If you are still bent on an ARC pre, I see that there is a SP-17 listed on A'gon for sale for $2300. It is a very good pre and will deliver a lot of what your looking for, but not everything (e.g., only SE inputs and outputs). See http://www.audiogon.com/cgi-bin/cls.pl?preatube&1300766954 Check ARCDB.com for details.

If those have metal dome tweeters than good luck with them and Bryston as the upper range in the Bryston is bright to begin with.A silk dome tweeter is better.

I'd suggest Conrad Johnson preamp, You have described Classic CJ sound.
