Next step after B&W 802D

By the way, with those speakers you really need a reference digital front end like a dCS or Esoteric before you can hear what they can really do. I would upgrade front-end components first.

Your amp speaker combo is a mismatch. You either need a 200 wpc plus solid state amp or speakers that can be driven by your 50 wpc tube amp IMO.

Depending on your musical preference:

Airy and holographic - Elac with mushroom head, Venture
Holographic with more weight - MBL 111 or 101
Razor sharp with details - Usher BE10/20
Pleasant with details - Analysis (forgot the model)
Dynamic & musical - Avantgarde Duo or above

I had the B&W 802 (non diamond) and went to the Wilson Sophia 2. The Sophia 2 is a great speaker. I'm now using Dynaudio C2 but I still prefer the Sophia to the C2 and the B&W 802. Agree with Bar81, see what you want to improve on. I wanted to improve on the bass and I couldn't get Bass from the B&W 802 because I was on the 2nd floor with cheap floor boards and I think the downward firing bass just went down stairs. My friend put them on concrete and they sounded completely different with much better bass.

With your amp, its not enough to drive the N802 as many here aired out.
I think your amp would work better with the Sophia 2 Or get one of those solid state amp from Accuphase and it will drive your N802 well.
