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.
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: 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: I have this receiver paired with two infinity primus floor standing speakers and an infinity primus sub. I was primarily interested in a system for music so the 2.1 setup works for me. I am still amazed at the clarity and detail this amp reproduces even at high volumes. Plenty of options for inputs is nice, though I mostly use one Aux in from my computer. Bluetooth is a plus though and works very very easily.
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.
Summary: I have been enjoying this receiver about a week now. I am not completely tech savvy when it comes to things like networking a million devices but I can say that as far a bluetooth is concerned and and the basics of an old time analog receiver, I am very happy. I only have bluetooth devices and a couple hundred LPs which is what I use most. LPs sound great on this system. I don't have CDs but I am sure they would sound great too.
Pros: Pros are the massive versitility and new technology while getting away from the surround sound thing and getting back to the basics of a STEREO two channel high powered receiver. For me a phono input is always one of the essenital requirements. I cannot imagine this unit being a dissapointment to anyone.
Cons: In regards to the cons of this unit, it is heavily dependant on the remote control. There is precious little you can do without the remote in fact. That includes adjusting bass, treble,and even balance, not to mention all the higher technologies that cannot be adjusted without the remote control. So, if you buy this unit, you will need to treat the remote with a lot of care as you are going to need it to work throughout the lifetime of the receiver.
