I own the B&W 800D and still do at this time. I had tried many amps on them: Mc 1201, ML 436, Krell 400cx and now Accuphase M2000. I found that the Krell was the best match for the B&W at your price point. See if you can get a 300cx for them. The other amps never got the bass out of the B&W like the Krell did.
