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.

Thanks BR. So the ICs from the head unit (CDP) still go into the "CD" connects on the integrated? CDP->integrated CD inputs->pre out to SVS SP12-Plus or BMC->if BMC, sub out to powered sub, how are the high frequencies amplified? is there a connect from the BMC back to the integrated, hence the main amp in? For this to work, there must be an input switch on the amp for the main amp in input, right? I would use this and not switch to "CD."
OR in a DECCO/amp situation, it goes Wadia->Decco->pre out to BMC->out to powered sub, how do I connect the high frequencies, are they connected to the Decco amp section>?
sorry, still confused...
