best solid state integrated to match with B&W 685s


Hi folks, I am new to Audiogon but love the site. I am just starting out on my trip to audiophile heaven, and currently I have 15 year old Yamaha gear (RX-485 and cheapo CDP). I bought the B&Ws in August and have been researching ever since.
The room is small, 14x12, and my music is intensely varied, from Snoop Dogg to Aphex Twin to Vivaldi. What would be the best integrated amps to start auditioning?
I am planning to eventually build a system with an external DAC and the Wadia iTransport, so am looking very hard at refurbished Deccos...Also considering the NAD C326 BEE, the Cambridge Audio 550a, the Music Hall A25.2, and a used Creek 5350SE if I can find it cheap enough.
Budget is under $800, has already been pushed to the limit.

Bob, I was reading that good transient response will help the sub sound more musical when used in a stereo music system, and that transient response is much more important with music than it is with HT. But I have also read that transient response is too subtle to be detected with the typical ear. So what makes a good sub in your opinion? As I browse the dealers' showrooms listening to subs, what am I looking for, besides an on-board active high-pass filter or crossover? What are the specs...?
I think Knownothing
had a good idea as I use a Denon 988AVR to run my B&Ws on a dedicated channel and they sound real good. I auditioned the 685s,705s,684s and the CM7 with it and they all had a great sound . Your gonna want a powerd sub with those also and the Denon will give you bass management for the sub along with the ability to do HT if you want or run sound to diffrent rooms. I just happen to have the Denon and like it and it's Burr Brown DACs but there are other good AVRs out there in your budget. Moer options and more bang for the buck.
TXdog - that looks like a nice unit, and I know Denon has been manufacturing quality HT AVRs for years, but mine is not a multi-channel system, and I don't think it will become one. We should talk when I start building my HT system in the living room - after my kids grow up a bit. They are 3 and 1, and I think any HT system in there would get trashed.
