HK 3700 is rated 4.5 out of 5 by 16.
Rated 5 out of 5 by from Very Good Sound I bought the HK 3700 to go with my HK 2.1 speaker system. The sound is excellent. This is audio only and does not support HDMI connection. The HDMI connections are made from the Cable box, DVD Player, etc. to the TV. Audio cables are used to connect the TV to the HK 3700. It's a bit of a headache for those of us who are electronically challenged. But, once the system is set up, all is well with the world.

Rated 5 out of 5 by from My new HK3700 I just received my amplifier/receiver. I love the quality of the sound. I also like that I was able to directly connect a turntable (without a separate pre-amp box.

Rated 5 out of 5 by from Replacement for unit purchased in 1969 I purchased a Harman Kardon amp in early 1969. It lost a channel in late 2016, which prompted this purchase. Excellent unit then and now.

Rated 5 out of 5 by from Great features! I got this for Christmas to replace an old 70's receiver. Surprisingly good sound. Pushes my 120 watt speakers with ease. Love having a remote and the display an extra bonus.

Rated 5 out of 5 by from Sounds fantastic! Had an older HK receiver, glad I bought Harmon Karden again. Easy hook-up, runs (2) sets of speakers and sounds great!

Rated 5 out of 5 by from Works like a charm. I bought this as a replacement for my NAD and I couldn't be happier. It came packaged great and worked perfectly out of the box. Sounds great and has a sleek interface. Would definitely buy this again.

Rated 4 out of 5 by from superb sound and design... ... however: HK remote app has an erratic behavior: sometimes the receiver appears, mostly not. (HK3700/network connection through RJ45, DLNA on, Iphone 4s ios9 / wifi network). No app update since feb 2014, this may explain that. The worst in my opinion: power off is working with the app, however NO POWER ON BUTTON (or any electronic entry signal detection on the HK3700). "Le son ancienne ecole rencontre la connectivite actuelle" ? A quoi ca sert la frite, si t'as pas les moules ?

Rated 5 out of 5 by from A big wrinkle at first, but HK made good. The first unit sent to me died within a week. Harmon Kardons' exchange policy worked as advertised, and they quickly sent me another. The sound is great, the amplifier was able to drive a pair of Kenwood MV-7's (550W speakers) without any decernable frequency loss. While some consider the lack of a balance control a downside, I have always been a stickler for good speaker placement.

I have Harmon Kardon Speakers with a sub, center, and 4 surround, the manual says HKTS 20 / HKTS 30 what receiver do you recommend I purchase to play this speaker system at their BEST? T e receiver I had blew a channel

Asked by: SLY 1956
The HKTS 20 surround speakers can handle up to 80 watts at 8 ohms and the center channel up to 120 watts at 8 ohms. While the HKTS 30 speakers can handle up to 120 watts at 8 ohms per channel. Any receiver with an impedance rating of 8 ohms and a power output of 80 watts per channel or less will work fine with these speakers.

Does this reciever have two zones? If so can they be played indepentely?

Asked by: audio1234
The receiver will allow you to connect two-sets of speakers and you have an option to place them in different areas. However, each set of speakers cannot independently play multiple source.

How can I play music from an iOS device thru dlna! &nbsp;I have bought various apps and have been unable to get this to work.

Asked by: Dana
There are a number of applications available for iOS devices to play through DLNA. One thing to make sure of is that the HK 3700 is properly connected to your modem/router with an ethernet cable.

Asked by: JERRY6557
While the satellites and the subwoofer would work with the HK 3700, this can only provide you stereo sound and not surround sound. The HK 3700 is a stereo receiver and the HKTS 16 is intended to be connected to a 5.1 A/V receiver to provide a complete surround sound system. An AVR we could recommend would be the AVR1510S which can drive 75W per channel to the HKTS 16's speakers that can handle up to 120W of power.
