Rated 5 out of 5 by from My second Harmon Kardon reciever I used my first HK until it was used up. This one has more power, more headroom and more features. I love it.

Rated 5 out of 5 by from HK 3770 is the Bomb! Just set this up, super easy; remote is a little hard to figure at first but is solid. The sound this thing reproduces is clean, rich, good lows, solid mids. My setup is 2x JBL Studio L890 towers and JBL Studio Sub 250P. It can push some some serious power and the Harman Sound button is a nice feature.

Rated 5 out of 5 by from Best value !!! I purchased the receiver a few months ago and wanted to share my pleasure with it. I am using it to drive a pair of PSB Synchrony II bookshelf speakers with a load of 4 ohms. The receiver drives these speakers with ease and sounds terrific. I have downsized from a much larger system ( due to a move to a retirement home ) and have no regrets whatsoever. All and all, this receiver is an outright best buy .

Rated 5 out of 5 by from Everything I was looking for. Box came smashed in from shipping company but thanks to the packaging it was undamaged, thank goodness! This thing is bomb! The sub out was a must have for my reciever. Bluetooth connects perfect with my Note 8, also a must have. Ample power, great product! Missing smart home connectivity.

Hello, I have the HKTS 9/16 home theater system. I am interested in the 3770 receiver. My tv is mounted and Im trying to continue the wireless look for my home. Can this receiver connect to my tv wirelessly?

Asked by: saran
Yes, if your TV has a Bluetooth transmitter since the HK 3770 has a built-in Bluetooth receiver. But with this set-up, you sources (like cablebox, DVD player, etc) needs to be connected to the TV instead. The you just select Bluetooth as the source for audio on the receiver. Also, you may experience latency or audio/video sync issues when watching TV with the Bluetooth connection. I would suggest using a wired connection when connecting to avoid the said issues.

I have a HKTS 30 and will this receiver work with it

Asked by: Akumar
The HK 3770 would work wattage wise but since it's a stereo receiver and has 2 terminals which means you can only fit 2 speakers to this receiver.

Hi, I renently purchased the HK 3770 from Crutchfield. Excellent unit! I just wanted to ask a question concerning the optical inputs; Can I use one of the optical inputs on the 3770, fed from a DAC that is playing FLAC audio? Thanks.

Asked by: TommyD
If you are using a DAC, I will assume you are using the analog output of your source, which is playing the FLAC files. The DAC is converting the analog source to digital, which is then connected to the optical input on the HK3770. If all of this is correct, it doesn't matter what format the file was (FLAC, MP3, etc.) when it started being that it was sent through an analog output to the DAC, so it will work perfectly fine.
