Rated 5 out of 5 by from Class A/B amplifier? check! This beast has 40 amps of current to provide to speakers and I tested this with 6 ohm speakers it is 50 % efficient which is typically for a class A/B the previous model it was a wonder of 310 w with 77% efficiency, guess Harman is learning to do proper SMPS, good clean sound in evry in, including the coveted optical coaxial digital inputs for lossless audio, high quality performance

Rated 5 out of 5 by from Great clean sound. I've had this unit for four months now and it's fantastic! I'm running JBL ES80 floor speakers and an Onkyo 10" subwoofer. I primarily use it running my PS4/PS3 and cable, but also use it for music. The DLNA features are great on this unit as well. I'm not an extreme audiophile, but I do appreciate good quality sound and this setup definitely delivers that and much more (Harmon Low/High sound). The only few things I wish this unit had are: Bass/Treble controls on the unit (currently accessible via remote only), wireless (currently only hardwire connection available), and an easier access to accessing your music via Network (currently it's very tedious to go thru a lot of music with no search feature). All in all, I'm pleased with the unit which I use everyday.

Rated 5 out of 5 by from Beautiful, full-featured stereo receiver I have a set of JBL tower speakers, and I previously had them connected to an Onkyo TX-8255, and they sounded great. Now that I have them connected to the 3770, I honestly think I hear a big enough difference in quality to justify the upgrade — even without the killer features; Bluetooth is definitely a nice touch for sure, and very convenient — I have my music collection playing wirelessly from my phone all the time, and so long as you stay within range, it sounds great. Five auxiliary connection ports for RCA cables as well; I have one cable with a 3.5mm end for connecting to MP3 players or whatever I like, and I’ve one more connected to my TV; three more ports left, and I’m not sure what I’ll ever use ‘em for. I can’t tell you too much about the technicalities of this receiver’s connectivity, but you can read all about that sort of thing on this website, or in the product manual. This stereo receiver packs 120 watts of power into two channels each (240 watts total), at 8 ohms, with .07% total harmonic distortion. This receiver is fantastic. If you don’t believe me, then by all means order one for yourself. Harman Kardon ships for free and charges no tax (at least in Illinois), and offers free 30-day returns and lifetime support. Go for it.

Rated 4 out of 5 by from Powerful and clean stereo receiver I have had this receiver for a couple of weeks now and it has proven to be a clean and powerful receiver. I was initially surprised at the light weight of the unit however it must utilize newer technology as the weight does not reflect the performance. Connected readily to my four year old Ipod as well as my new IPhone 5. Still exploring other aspects of connectivity as I am interested in high resolution music files. Instructions are sketchy with limited assistance to connectivity or other control or performance capabilities.

Rated 3 out of 5 by from I am updating my past review. When I reviewed this receiver I was very happy and everything worked just fine. 3 Months later and, the bluetooth connection just disconnects with out any reason. The unit shuts off for no reason what so ever, just dead. If we do too much to it, say connect iPad through bluetooth or have, say the Phono on, it shuts down. When in operation without difficulty, it is a wonderful unit but we are adjusting to the volume controls which when they are in low numbers, the volume is high, when the numbers are high, the volume is low. Very good chance we may send this back as it could be a faulty receiver but we defiantly are happy to replace with another just like it and we ARE going to buy another just like it for our family room, it is that good in our minds for the money. Sure, more wonderful units out there cost more but for our budget, this is the best we could find and we hope to have the problems fixed. Someone else reviewed that the unit seems cheap or there was some issue with the plastic, etc. We noted nothing of the sort. This is a clean, fine, well made although light in weight, receiver with lots of fantastic workings. Our will go back but we will replace with like unit.
