I initially auditioned my B&W CDM1nt's on a Denon 5802...probably not tooo much different than the 5803...At home I use a Bryston B60 integrated amp and in my opinion, it hands down is the better sounding of the two...even with only 60+ wpc...and this is a lower end integrated...the top integrated amps (Levinson/Rowland/YBA/etc) would probably be even much better than the Bryston even though I have not heard them...so I would have to say that my opinion is that no...the 5803 wouldn't come close for 2 channel.
