My C2700/MC611 system is excellent. Mid-bass/bass to die for. I do agree about the highs. I fixed this issue by pairing Nordost Valhalla 2 XLRs between my DAC and the C2700; boy, what a difference! It has transformed the MAC system from top to bottom.
I went from a Luxman 590 AXII to my current McIntosh system. The Luxman did not have enough power to drive my speakers. I did compare the McIntosh to the Luxman M10x and accompanying preamp. The Luxman is fabulous and more detailed than the MAC. However, the MAC is warmer and far more powerful with thunderous bass. My preference is for warmth and bass as exemplified by the direction I headed. It's all up to what your ears tell you!
