What amp are you using? I own the Compact 7es3, and used to think they did everything wonderfully except rock. I recently changed the amp from an LFD integrated to a Naim NAP200 (driven by Naim DAC v1). Now the C7s do everything wonderfully including rock. The NAP 200 has energized these speakers and brought solidity, definition, and control to the low end. They're still not monsters of slam, but I'm not yearning for a more dynamic speaker. The C7s do so much right that it might be worth considering a change in amplification before a change in speaker. Just a thought for the day...
