Rated 5 out of 5 by from Great for vinyl! Using this and a turntable for a trip down memory lane with vinyl. First remote they shipped had exploded batteries in it, but they shipped a new one with one phone call.

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 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 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 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.

Too bad the USB capability is so limited. If the USB supported standard audio USB drivers so I could use it for input from my computer system I would have bought one of these.

Asked by: todji
Unfortunately, The USB port on the HK3700 is only for USB thumb drives to play MP3 or WMA audio files and for pushing Firmware Updates.

Hi, Is there any way to connect my iphone using DLNA and listening songs on youtube on this receiver? I tried some DLNA streaming applications but they didn't work.  Thanks!

Asked by: Gabor
DLNA allows you to stream content from a compatible device to another that are connected in the same home network. The HK 3700 is DLNA 1.5 compatible which would allow you to stream Audio only via the home network. As an alternative, if your TV support screen-mirroring, you can directly stream your Youtube Application to your TV using this feature.
