Looking for a simple system

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.

I’d go for the Atoll and get these Joseph Audio Pulsars.  Best of luck.

IMO, as mentioned in other posts and reading many reviews, and I’ve auditioned them for hours, get the Kef LS60’s and be done, maybe get 1 or 2 of their subs. This will outperform most of the gear mentioned above and be the simplest to own and use. If you compare the technical aspects of the features the equipment mentioned above, the Kef’s has more features and the sound quality is fantastic. 

I would also seriously consider the Kef LS60. Huge sound value with all the features you seek.

Might also consider a preowned pair of Dynaudio heritage specials or Contour 20.
