Selling my beloved KAV-400xi because I have upgraded. Tons of clean power in one package. This is the second best amp I've heard with the HE-6 (best being the my successor which cost much more). The amp is in very good cosmetic condition, probably rated a 9/10 on the agon scale.
Comes in black with remote and stock power cable; shipped in original Krell box. Price includes shipping in the CONUS. Paypal only.
