My two cents: I've owned an Atoll integrated (IN200SE) and it paired really nicely with the Fritz Carbon 7 Mk. 2 SE. It had good power and just a bit of extra energy in the mids and highs, so the Fritz's speakers warmth and soft dome tweeter were a great match with that amp.
It's no secret how much of a good value I think Fritz's speakers are — especially given that there is no overhead, marketing, advertising, etc. I really believe they are easily the equal of speakers more than 2x their price. Review is here.
