802 diamonds with class d amp

There is no XA600.5 only a X600. The A in the XA stands for Class A Watt amps. The X amps are Class A/B.

IMHO the Class A Pass Labs over the none Class A is the way to go if you decide on Pass. With the 802D you will need at least the XA100.5 but that might fall short. Then it would be the XA160.5. However the XA200.5 is the one to get but I doubt you will find that used in your budget. Maybe the XA160.5.

Please keep in mind that they are very heavy, large, can heat a small house and use gobs of electric. But they are great sounding in their Class A variant.

You asked about Class D in your OP. You should check out the Hypex Ncore NC400 DIY or the Hypex Ncore NC1200 OEM amps. Some OEMs provide in home demo.

Good luck with your choice.

I mean X600.5 of course

The B&W 802 Diamonds sounds great with Krell amps, especially 600E.

Pass Labs is better in sound realism than Krell. The nautilus top is exeptional good in focus and also in sound realism. Your speaker will get to a higher level in real live sound.
