I run all krell. fpb 300cx Old style face. Kps25sc with old style face. I love the older battle ship gray. The previous owner had the amp upgraded internally but left the older face. My gain. The Kps25sc was upgraded by me from Krell and is the best thing I have done in audio in 20 years. OK its a tie with my CLS build. I use the silver CAST cables and that alone is so much better than any XLR I have had in line. I am constantly looking to improve , However when it comes to power and balls to the wall smoothness the Krell has no rival. many say they are not to their liking as they NEVER have heard them set up right. Done right Krell is mellow when you want it and ballsy when you need it. Combine that with the CAST and the signal transfer is as fast and clean as it gets. Blacks are blacker and depth to die for. I see know reason to look elsewhere right now!
