KN2600 sounds excellent here. It is making money for me, and everyone that hears it is very impressed.
There is a lot of control over the output sound quality on the KN2600 so if it doesn't sound good it is in your own hands!
The KN2600 puts out 40 Watts and if wound up enough can be pretty loud. If you need more clout hook it up to a Logitec Z2300 or something.
The KN7000 is nice, but just too heavy to be practical for me. After years of Yamaha I am hooked on the KN2600!
Cheers,
