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

I would like to stream hi quality (FLAC) music files from Tidal. Their website lists HK as compatible. &nbsp;will this work? Can i either stream directly via Ethernet input or via Mac mini to optical in? Control via Tidal plug in to HK remote app on iPad?

Asked by: Craig S
The Tidal Streaming App is currently only compatible with our OMNI Speakers (OMNI 10, OMNI 20 and ADAPT). To do this, in the Harman Kardon Controller app, tap on the main menu icon in the left top of the screen (&equiv;). Choose TIDAL and log on with your TIDAL username and password.

I HAVE A PAIR OF SPEAKERS 3 WAY 200WATT RMS. AND A PEAK OF 400 WATT. WILL THIS RECIEVER POWER MY SPEAKERS WITHOUT Stressing IT

Asked by: Joseph B
The HK3770 can drive up to 120W to a 6/8-ohm load speaker. As long as this 200W RMS speaker of yours has an impedance of 6/8-ohms, then it should work perfectly in tandem with the HK3770. If you are using a 4-ohm speaker, you can still use this with the HK3770 but you can only maximize one of the two pairs of speaker connections available in the HK3770. Do not forget to keep the unit well ventilated, to avoid fatigue, when using 4 ohm speakers.

Is there a large enough difference between this receiver and the HK3700, to warrant purchasing this receiver? Also there are muliple different speaker systems to go with this receiver, of the Hartman Karon set ups, what is the best receiver/speaker combo?

Asked by: Nsteuwe101
The main difference between the HK 3700 and the 3770 is that the latter can accommodate digital inputs (optical, coaxial). While there is no such perfect setup since it is all a matter of preference, there are a couple of speakers that would work well with these stereo-receivers. As of currently, speaker systems available in harmankardon.com are 5.1 systems, you might want to check loudspeakers available at JBL.com which should work well too.

On the HK3770 or HK3700: &nbsp;where can I plug in audio from a TV? &nbsp;Most receivers have an aux audio input specified for this. Do I just choose one of the 5 &nbsp;inputs?

Asked by: Ray B
The HK3700 can accommodate audio inputs via analog/RCA connections while the HK3770 allows you to connect a source via RCA, optical or coaxial. You can use any of this inputs (except Phono) to connect your TV and you simply need to make sure that the TV is set to use external speakers and that the HK3700/3770 is on the correct source, depending on which port you&rsquo;ve utilized.
