Amplifiers for B&W 803D/802D

I'd go for the 803D. To me they're better balanced and can work off the lesser power amp but they still need plenty of power. I would recommend 803D with either MC501, bigger Classe, Pass X250.5 or X350.5 or the bigger Levinson amps.
I heard 803D and 802D and I honestly think 803Ds are a better choice, unless the room is gigantic.
Don't forget, 803D are capable of playing very loud very clean. All they need for that is a proper amplification.
Regardless of which of the 2 speakers you choose, I don't think MC402 is the proper amp if you want uncompressed dynamics and soundstage. MC402 would be fine for low level listening for 803D but it would not do the dynamics the way some of the other amps would.
With B&Ws, amplifier is the most important component.

Thanks for responding Audphile1. Please bear with me as I am new to high end audio and am still learning.... If the MC402 is 400 watts per channel and the Pass Labs is 250 watts per channel how does the Pass Labs outperform the Mcintosh? In other words how does a 5x250 outperform a 2x400? Is the Pass Labs simply a more efficient amplifier or does it just "sound better" because of its components...? The 500w mono Mcintosh sounding better is easier to understand for me. By bigger Classe , do you mean the 400w monos or is there a multichannel Classe that would do the job e.g the 5 x200....but again, how would a 5x200 Classe outperform a 2x400 Mcintosh? A multichannel would certainly give me more flexibility. Thanks so much; your patience is appreciated.

Sorry Audphile1, I just looked it up and realized the PassLabs you mentioned are monoblock amps...my mistake.... so it sounds like in your opinion monos are really the way to go with these speakers. Are there any multichannel amps that would be suitable? multichannel gives me more flexibility for possible conversion to surround sound later on. How about bi-amping a 5x200 to get 400w a side? How would that compare to separate monos? My local dealer is really pushing the 5x200 Classe. Thanks again.

Statusnine, your first reply to Audphile1 were excellent questions, as IMO his comments were without merit and didn't make sense. The Pass amps he suggested are NOT mono-blocks, as you state in your second reply, they are two channel amps, just as the MC402, yet they are very good amps as well.

Take the time and go to your dealer and listen to each setup he suggests. You can determine if you really like it or not. Even better would be if he'd let you take home the setup you prefered best in the store to try, but speakers of that size are not always allowed out for loan.

If you go with the 802D's, I suggest mono blocks. Just my opinion.

Statusnine, McIntosh and Pass are very different amps.
X250.5 is a 2-ch amp, 250w/ch into 8ohms. It doubles into 4 ohms. It's a different design from MC402.
X250.5 provides about 36 watts/ch of pure class A which is great for low level listening. Also, the Pass amp is more dynamic, effortless and explosive than the McIntosh. MC402 is a fixed 400w/ch no matter the load. B&Ws will dip into a 3ohm territory where the X250.5 will have an advantage over MC402. I heard MC402 with 803D and own X250.5 and to me the X250.5 is a better performer.

Bottom line is - you got to do your own research which should not be limited to these forums. Listen to as many amps as possible and draw your conclusions from there.
