@paliden - You seem to have decent enough cables. If you want a nice amplifier for the main channels, I can suggest you try an Odyssey Audio Kismet amp. Depending on your budget, if you can get the top of the line amp (or monoblocks), I think you will be pleased. I have upgraded my Odyssey Audio Stratos to full Kismet internals, and the sound is glorious, rich, detailed, spacious and very dynamic. Another choice (and one easier on the back) are the Arion Audio amps. Among the best Class D amps I have heard.
