I have a living room setup with two Sony SS-F7000 floor-standing speakers. This amp powers them very nicely for my purposes. To me it sounds perfect - strong bass (main concern before buying) and with bass/treble controls that I leave set in the middle. In this fairly small room, I use it up to about 1/2 volume (at which point it is way too loud).
I don't want the complexity of a Stereo receiver with source selector, and so I combined this amp with a simple mixer.
This way I can have all my sources always on, it's just a matter of starting/stopping them.
I am going to replicate this setup for all my rooms, potentially with a smaller speaker like SS-B3000 which I already have a pair of (also sound ok with this amp). The single sound source in the other rooms will be an Apple Airport Express, for sound distribution. So far I'm really pleased with the sound setup - simple, cheap, and music to my ears.
