I have recently plugged my KN-6500 into a set of A/L 621 spoeakers along with my Dell Computer which is plugged into the spare input on the Sub-Base. You will find no other speakers anywhere near the quality of the 621's, and there absolute low price is also un-beatable. I was about to purchase the new KN-7000, but the 6500 sounds so sweet and rich, with this speaker system, I no longer am considering that purchase, at least at this time. ARJ
