Rated 5 out of 5 by from great product mine doesn't cut off for no reason, or get hot at -35 db to -45 db. also it has an internal cooling fan that kicks on at higher volumes -10 to +10 db. (max volume) it pushes my jvc 15 (sp-7700) speakers (8 ohms) and a set of bose 701 all (6 ohms) at once. only reason it would cut out is if your ohms rating is wrong for the stereo. (6-8ohms) 2 or 4 ohms is too much resistance and 16 ohms is not enough and will not play as loud. i love this amp i am one to put it to the test playing it full blast for hours, and it holds up very well. yes it will cut out if you crank it up for 5 mins turn it down 30 seconds then turn it up back and forth. fan cuts off when you turn it down and if you turn it up right away it does not give enough cool down time before fan turns back on... so if you gonna do it loud keep it loud or leave it down for about 10 mins between sudden bursts. (thats with all audio systems though) older systems did not have self protect mode from heat. and i cant speak for the older hk model cause i don't have one i got the hk3770. which was an upgrade from my pioneer 1986 yeah sa-1270. electronics are all sensitive!!!! this is a bi amp capable amp for bi amp speakers or you can run 2 sets that are not bi amped

Rated 5 out of 5 by from Good affordable high current amplifier! Excellent receiver! The only thing I consider important that need to be said is that you need to get the update from harman pardon european site version V000.17 it comes with V000.16 and it adds Balance controls in the tone control button of the remote controller It is in th download section at then end, unzip the file and you will find a pdf with all the instructions to install this very important upgrade http://eu.harmankardon.com/harman-kardon-product-support-detail-eu/hk-3770.html

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.

What stereo receiver will power my Bose 901 series 1V speakers?

Asked by: Willy
We no longer manufacture any receivers that have Tape Loop or Preamp Out/Main Amp In sections, which is what your Bose 901 speaker system needs in order to function properly. Unfortunately we have nothing that will accommodate your needs.

I would like to buy another HK 3390 for a friend. I own this model, and am not sure that the HK 3770 is an adequate or similar replacement. Comments, please; holding on order!

Asked by: JMac 1763
The HK3770 has updated features compared to the HK3390, for example the HK3770 has network connectivity which the HK3390 does not have. But both are the same in the aspect of the speaker setup.It would really boil down to what you need in terms of functionality and features.

can this receiver power 3 speakers, one woofer and two surrond sound speakers?

Asked by: Pauly
Technically all the speakers you just mentioned can be connected to this unit and be powered at no problem using the left and right connections, but I believe you are referring to an AVR receiver that has the capability of giving you the best possibility sound of a 5.1 system 2 fronts, 1 center, 2 rears and a subwoofer that will give you a theater sound or digital dolby sounds.

Can I use a Bose 901 series VI speaker together and its equalizer with the HK 3770?  Thanks

Asked by: Sonny
In the old days the BOSE 901 speakers required a Tape Monitor loop in order to work, but these days with digital inputs, Tape Monitor loops no longer work. So today, a receiver must have a pre out/main in loop in order to work. None of our current receivers have this feature or ability.
