Rated 5 out of 5 by from Superbly Powerful I purchased this about 3 months ago as a replacement for an AVR 8000. I too was concerned as to wether the newly designed amplifier in the AVR 3700 was still able to produce the same seamless power. It does. This receiver sounds just as beautiful with your favorite film as well as your favorite track. I cannot say enough good things. The on screen user interface is extremely intuitive and easy to use.

Whats the best amp you recommend for the HKTS 20 that has bluetooth, wifi, optical and HDMI?

Asked by: JorgeRBQ
The AVR 3700 can be connected to the home network to play through DLNA/Airplay but does not have Bluetooth. The AVR 1610S would be your best bet, this receiver can provide you 85W per channel on a 5.1 system, ability to connect to a home network that will allow you to access vTuner Internet Radio and DLNA to stream audio from compatible devices. The AVR 1610S does have Bluetooth in which you can directly connect your Bluetooth enabled source devices. This model does have multiple HDMI and Optical ports that you can use depending on your source or preference.

Does the AVR 3700 and/or AVR 1610S Amp work with the HKTS 20 Home Theater System?

Asked by: JorgeRBQ
Yes, both the AVR 3700 and the AVR 1610S would work with the speaker for the HKTS 20. Though, the AVR 3700 can drive 125W per channel, than what the speakers can safely handle, which is 5W more than what the speakers can handle, it can still be advisable. The AVR 1610S can drive 85W per channel which can be handled safely by the HKTS 20’s speakers which are rated at 120W.

I have a Harman Kardon AVR 247.  Could you consider the Harman Kardon AVR 3700 a modern day, or up-to-date version of the AVR 247?

Asked by: Ed647
Yes, you can consider the AVR3700 can be considered the most updated version of our AVR's. The AVR3700 has a lot of function that the AVR247 does not have, i.e 7.2-channel wireless network-connected audio/video receiver with 125 watts per channel output. Apple AirPlay, High-Definition Dolby® and DTS® surround-sound decoding, multizone functionality and 4K video scaling.

Can I use this amp to connect my ffloor standing speakers bi-amp? With double wire! 

Asked by: Abdulrahman
Thank you for your question, you can use bi-amp configurations using external amplifiers but if you will be using the wire terminals on the back of the AVR 3700 you may not achieve the stereo configurations. you will then need to assign you will have to enable 5 stereo Channel, dolby digital will separate your audio.
