Full disclosure: I have never heard powered speakers.My only hesitancy about powered speakers is the hassle of return or repair if something goes wrong with the amps. My current integrated is a McIntosh MA7900. It is my second MA7900. The first had a faulty DAC (not a problem with the amp itself but still...) and I returned it. That was enough hassle, I can't imagine dealing with the return of an ATC tower speaker because of a problem with the electronics. If you live close to your dealer, not too much of a concern. But if, like me, you live in an audio desert or buy used, it is something to think about.
