Bryston 7B SST2 + Aesthetix Calypso ???

I have heard the Aesthetix Janus coupled to Parasound JC1s and this is a very nice match up, very sweet, warm and detailed. My guess is that, with Bryston in a similar sonic realm as Parasound (I've previosuly owned both brands of amps and specifically the 7BSTs), the results with your proposed combination would be in the same ballpark and would be quite satisfying.

I own a pair of PMC IB2i's (currently for sale due to new purchase of ATC Actives) and an Aesthetix Signature Calypso paired with a McIntosh MC352. The MC has an input impedance of 20k ohms SE, 40k ohms balanced. The Calypso sounds beautiful with this combination, preferred over my McIntosh C2300 preamp. I think the Aesthetix/Bryston combo would be fine in terms of impedance matching. On another note, the Calypso doesn't seem to be a good match for my new ATC actives which have an input impedance of 10k ohms which is the "minimum" Aesthetix recommended amp load. Experiencing some bass rolloff with this combination.

Thanks, guys. You've confirmed my thinking.

Ssolman, out of curiosity, which ATCs have you chosen and in what ways do they improve upon the IB2i with the Calypso/Mac amplification? BTW, if you plan to sell your Calyso Sig, I might be interested so drop me an email.
