I like them just the way they are. When I listen to my KLF-20s I think "there cannot be a better sounding speaker on the planet for under $2000." If there is I haven't heard them. I love to blast MFSL's versions of Rush's Moving Pictures and Signals.
My system is a little odd, but here it is:
Adcom GTP-600 Pre-Amp [ old and has no DD or DTS but it has 5 channel stereo and it is a good sounding Pre]
Adcom GFA-7500 Amp
Adcom GCD-700 cd
Sony DVP-NC655P DVD
Klipsch KLF-20s Front
Klipsch KLF-C7 Center
Klipsch KG 5.5s Rear
Klipsch KSW-200 Sub [that I never use]
Like I said, she is a little odd, but I have friends that have spent thousands more on speakers and hardware and when they listen to my system I can see them turning green with envy!!!!
