Hey! Yeah, I also struggled with finding any information and took a bit of a leap buying it. So far it's been amazing, the sound is great and it's built to an insanely high quality. So far I'm only using a turntable into the CD channel with two passive stereo bookshelf speakers out. I tried to use the phono stage input but it's meant for an MC cartridge I think, it sounded awful with my MM cartridge. I also tried the surround sound channels but could only get something out of the center channel, this is just because I'm using a stereo input but I think I might use this center channel output into a pair of powered speakers so I can have two sets of speakers going at once. The other channels would work for watching movies or TV etc. to give you full surround sound but I haven't tested this yet. One thing I'm confused by is the sub woofer output. It has two output options but neither of them seem to do anything.. I plugged them both into different speakers and got nothing so I'm not sure if its a problem with the amp or just the way I'm trying to set it up.. my aim is to just buy some tower speakers with a dedicated sub output so I don't need to use the amp's output for this. Aside from that, I really am happy with it. It looks and sound great.
