Cheap Bryston active or Creek OBH12 passive?


My first audiophile-grade system is in need only of a preamp:

Joseph Audio RM22si signature speakers
Music Hall CD 25 CD player
McIntosh MC2105 amp
Kimber 4TC biwire speaker cables and Signal Cable 2 interconnects

So far for preamps, I've tried using my Denon home theater receiver as well as no preamp (going straight into the McIntosh amp and dialing down the gain controls). Using no preamp wins for clarity and musicality over the Denon for sure (the Denon adds a murky layer over the music), and it seems to be a good match going CD straight to amp (Mac has a very high 220k input impedance). But it's not practical to keep switching cables, so I need a pre. I want to get something cheap for now, around $200 used. I listen to all types of music, from rock to vocals to classical, but more rock than anything else.

And now the simple question: In this system, what do you think would sound better, a Creek OBH12 passive, or a Bryston .4B, .5B, etc? If the Creek wins in your opinion, I'm curious to know roughly how much you think I would need to spend on an active pre before it would start sounding better than the passive. I'm only considering solid state right now, don't want to worry about replacing tubes just yet.

Thanks,
Matt.

I agree w/ Marakanetz in principle, but you must be sure that your source has high enuf output and your amp has high gain. If your source output is over 2v and your amps sensitivity is less than 1v, and you use short cables, you should have no problems at all using the OBH12, and you would have to pay some big bucks to get a SS preamp that neutral.
matt, you're in great shape on your amp sensitivity and pre to amp cables. I don't think the length of the cable between the CDP and the preamp will be a problem. The only question is whether or not your CDP can drive the Mac. With the Mac's gain at .5v my guess is that this would not be a problem. And once again i agree with Marakanez re a small loss due to the CDP output would be preferable to a cheap SS preamp (of any manufacture).
