Dynaudio C1 Bass

I have owned my C1's for about two months now and they have rock solid bass down to the mid 30 hz. range.
Right out of the box they had much more bass output and extension than my previous much larger floorstanding Canton Vento 809's.
The problem sounds like a room/phase related issue.

Originally I was using a 100 wpc Mcintosh Integrated amp and it just did not let the C1's perform at their full potential. After switching to a Krell that more than doubles the output of the Mac into 4 ohms it is a whole different experience. I would not hesitate to use a high quality/high current amp that can produce 500 watts or more per channel into 4 ohms with these speakers. It seems like a lot of dealers feel that smaller amps work ok, but they really will not let you truly experience the incredible sound they can provide.
