While I agree that McIntosh, Musical Fidelity and Pass Labs are good choices, like
Saackesc, I recommend Accuphase amps for B&W speakers from the 800 series.
Accuphase is IMO a significant step up from the brands mentioned above, but it
is also more expensive.
Regarding the 803D vs. 802D issue, 802D is without a doubt the superior
speaker. If you have the space for the 802D and can afford it go for it. Buying
the cheaper model is never cheaper in the long run.
