Summary: Received the S500BL a couple of days ago -- nice quick free shipping service -- and have it running to replace a 30-year-old Sony 500ES amp coupled to a 35-year-od Advent Model 300 amp/tuner. (Ya, I'm an old guy.) I use it only for audio, not as a home theater accessory. First impression: the sound quality is nice and precise, both through my outgoing Advent speakers and on my new Klipsch towers.
Summary: I love this stereo receiver. I bought it because my years old Sony finally died. I needed a receiver that had multiple RCA inputs and a Phono input. I still have LPs! This receiver fit's the bill and doesn't have HDMI lots, that I didn't need. It's a great replacement for my failled unit.
Summary: The Amplifier was as advertised and works very well. I had a hard time finding one with all the connections I needed for my component system and those I did find were quite expensive. This one is worth the money!
Summary: When I set it up, initially there was no sound coming out of the speakers. Of course I checked all connections, wires, etc. I left it alone for a while and then came back and it was all fine - I have no idea what happened - I can't imagine it was because it needed to warm up. But once it got going, it was absolutely great.
