Recommendations please for good, affordable pre-amp for system?


Hi All, 

I'm configuring my first system, and have so far acquired the speakers (Thiel 3.6) and amp (Bryston 4B SST). I believe I need a preamp to complete this (and I believe only a preamp, right?). And I'm hoping you can give me some leads, information, and recommendations.  It's a 2-channel setup, and while it would be nice to add some HT capability in the future, I'm seeking as pure a sound as possible.

Some things I've looked at are Theta Casablanca, Bryston 0.5B, and perhaps for future upgrades, model Rotel RSP-1582 and Marantz AVR8802 -- although I'm concerned that those latter two, while brining nice features, will work to molest the signal.

Prime listening will be CD, with some lossless Network-attached storage, and Airplay with Tidal or otherwise Internet radio.

Thanks for your recommendations!

But not BP 0.5 or BP 1, I would presume? Good info. Would you imagine that staying within a brand is generally a better, more compatible way to go, in terms that they know what they're trying to achieve end-to-end?
@jond , Donzi bought the Theta Digital Casablanca 6-Channel Preamp Processor.

You are in a great position to try a silk tvc. You can tame the amp with proper interconnects.


@jond , if you scroll down, you'll see the details below the top stuff. 

I like the thought, expressed here I earlier think, that buying the preamp is as hard as the speakers. Surprisingly to me, although budget is not unlimited, I find myself a little bit expecting a process of buy-play-try. I anticipate, as long as I keep to auction and used, I can try, and recycle, and not get hurt too badly. Although surely the best is to find a local dealer who can demo this element is best, I think that's going to be hard in my area.

I expect to receive amp and pre within a few days. I'm looking forward to plugging this in and beginning this new life of audio!
