Best preamplifier, amplifier for B&W 800 Diamond


Buying the new B&W 800 Diamond speakers (already installed). I was wondering who has first hand experience which preampifiers and amplifers sound best with these speakers. Sound quality is the most important issue, not necessarily price. Any feedback would be appreciated!

B&W + Krell used to be an excellent match (with the FPB series of Krell).

There isn't much to find on the internet about their newer amps, but if I was the one installing a pair of 800 Diamonds, I would want to hear a full Krell Evolution system w/ Cast on them.
Hello , I 'm using an ARC REF 3 preamp , with 2x BAT VK1000 poweramp to drive the B&W 800 , as the BAT is a double amp , I use one amp for the lower , and the other for the mid / high . Ofcourse each amp has his own loudspeakercable .For me its a marrige in heaven , have heard the 800 often with Classe amps , but never was impressed.Front end ARC CD7 (improved, mod ) same as REF 3 , TT Sphinx PJ 6, ET airbearing arm , Te Kaitora cartridge and ARC PH5 ( mod ) pre pre .
I use VTL MB-450 mono blocks on mine & could not be happier. The tubes do a good job of taming the sharpish highs of speakers.
You will want to check out the Spectron Musician III amps which are a very popular choice with the 800 series. That's what I use with my 802d. The joule pre is another popular one. I personally use a Cary SLP03 for my preamp.
