Summary: Good sound quality, good build, if you now what you are looking for and check properly the connections available then enjoy lossless audio like I do This not an AVR so it doesn't process dolby digital or DTS this is a pure stereo receiver that marries some newer connections and with some old school features.
Summary: Terrible, terrible quality product. I was sold the HK 3490 to last, at least, 15, 20, nay 25 years. It just broke down 5 months after the end of constructor warranty. Planned obsolescence ? As someone report here, HK 3770 is even worst than HK 3490. It simply misses features that are necessary on a HiFi amplifier. Searching through the internet, I came across forum, feedback which report the overall decline in quality of HK.
Summary: This amp sounds great and has plenty of power to push our old Cerwin Vega speakers with 15" woofer, 8" mid and 3 tweeters. It gets way too loud before any perceivable distortion. One small gripe is the lack of tweakability: not much in the way of customizing EQ. There also aren't any different modes, like for movie or music settings. But, so far we are loving the sound anyway.
Pros: Great sound. Plenty of Power for large speakers. Looks good. Good price. All the inputs we needed. Bluetooth works great.
Cons: Lack of EQ control. Lack of sound presets for different sources.
Excellent choice for bridging the analog/digital audio divide.

Summary: Out of the box, the HK 3770 is a nice looking unit. The Black plastic face reveals elegant white text indicating modes, features and menus. Thee is a large, soft luminous ring around the volume knob as well. Set up is easy and straightforward, if you are slow and methodical about it. Once powered on, the HK 3770 is a powerful tuner with a very deep and satisfying feature set.
Summary: I originally bought an HK 3490 and was very happy with it until it suddenly died. When I contacted customer service, they said they had sold their last 3490s but could send me the new version instead. Naturally, I said that would be more than adequate. In this case, the new model is a huge step back. Despite claiming the same power (120 wpc), it's not nearly as strong. Setting this to -15 dB gets the same volume as -35 on the 3490.
