I have a Cinepro 3K6-III and an EAD PM2000 that I use to help active tri-amp my mains, and perform HT duties. I also had some Bryston 7B-ST's and a 4B-ST at the same time too.
Though my PM2000 is my favourite, the Cinepro's ultra-low noise floor really lets "extra" music to be heard. It also has great user features with adjustable gain for all channels, and bridging of channels. It's speaker binding posts are spaced a little close together though, but it is a fine amp !
I use the Cinepro to power my mains' tweeters, and my 4 surrounds. My EAD powers my mains' mid & bass, and my centre channel.
My mains have 2 12" drivers each.
I easily prefer the EAD for bass duties, followed by the 7B-ST's, then the Cinepro. I would rate the Cinepro bass ( with my speakers anyway ) similar to a 4B-ST, IMO. Of course, you can always bridged a pair of Cinepro channels too. For the bass drivers is your B&W 803, I would think the Cinepro would have great bass response, and would be a great choice. ... just my 2 cents.
