Preamp matching for Krell FPB amplifier

If you are an FPB amp with no cast then the new Krell KAV preamp is perfect for that beast. It is esentialy the KCT without cast and paired with XLR cables you will get the most neutral and pure (unmolested) sound.

Krell is a lot better in designing poweramps than preamps. I'm just auditioning preamps with the FPB 600C, I prefer a preamp which keeps it's possible aggressiveness under control. I like the Pass X2.5, all natural sound colors and textures can be heard (btw. a lot better with the 600C than with the Pass X250). I also like the new Nagra PL-L, it has a nice and subtle tube sound and also keeps the highs under control, however the Pass lets me hear more good things of the original recording (the Nagra is not broken-in yet, so it might improve).

Have an option of getting a mint 2nd hand KRC for the same price as KAV 280p to go with a non-cast FPB.

Which do you think is a better option? The KRC used to be their top of the line preamp and the KAV is the current entry level - would technology have improved so much to make a previous top of the line preamp inferior to a present entry level one?

I use my system as Video & Audio and the Theta Casablanc II matches with my Krell 650M's perfecly. Very, Very, Detail, Open Soundstage, Excellent Mid and thunderous Lows.

Hi,

I would suggest one of the excellent tube preamps from Consonance by OperaAudio or Power modules. You will have the best of all worlds!
