802 diamonds with class d amp

I can't speak to class D amp options having no familiarity with them. I have B&W 804 Diamonds (the current 2nd gen) and use Musical Fidelity's M6PRE (class A) and M6PRX (class A/B, 260w dual mono) which pair nicely with 804 Diamonds and didn't put me in debtor's prison. MF makes an M6 500w integrated that lists new for $7000. I suspect it would work well with 802 Diamonds. There are a couple of M6 500i demo units listed on Agon right now both under $5k. Just a thought. I have no connection with either seller.

With the B&W and Musical Fidelity components that I'm using and given their price points, soundstage width and depth is acceptable but definitely not exceptional. For me, the ability to reproduce the sound of different instruments with realism and clarity across high, mid, and low frequencies is a more important consideration than soundstage width and depth. In these areas the B&W and MF components I'm using are exceptional given their price points. Certainly if I could afford Pass Labs amplification, I'd be waving goodbye to MF and using something else.

I can relate. It is incredible how much relief and joy can result from a simple repositioning of speakers. I suspect though that an amplification upgrade would still produce further easily perceptible and significant improvement. Either way, happy listening!
