Rated 5 out of 5 by from Full featured, value priced, decent quality. (Purchased from Best Buy) Super value priced for use in my office two-channel music system. Program sources are Apple AirPlay streaming, HEOS, Internet radio, FM and occasionally audio CDs. Blue tooth capability will be a back-up to Apple Airplay. After brief burn-in, I am very pleased with my choice. I have set the tone profile to Pure Direct. This is not a top-end receiver, but it is also priced at 1/20 the cost of a McIntosh receiver. As a value proposition, it does the job - admirably.

Rated 5 out of 5 by from Fantastic sound We upgraded our old receiver to this one and couldn't be happier with the sound quality. Thank you Danon ...Amazing!!!!!!

Rated 5 out of 5 by from Best Amplifier for a top system I purchased the amplifier for my home entertainment to go with my older Denon speakers and allow an HDMI link to a Roku and Apple streaming system. The installation was a breeze and the sound is amazing.

Rated 5 out of 5 by from Amazing sound, what you'd expect from a Denon The amp is equally important as the speakers. When my older stereo amp died, i bpught this unit to replace it, and i have fallen in love with my music collection all over again. I was missing the details that the Dolby PL II was pushing out to my Klipsch reference speakers to a 5:1 configuration. Regardless if you are a novice or a music audiofile, you won't be disappointed. Im reminded that you get what you pay for, and this receiver is worth the extra few bucks.

Will the amp output to speakers and headphones simultaneously? I have a ReSound audio streamer which sends audio direct to my hearing aid. The streamer will take either an Optical or headphone input.

Asked by: jcinnb
Hello, Connecting headphones to the AVR-S660H's headphone port will result in the speaker ports being shut-down. As there is no optical output (very rare on AVRs these days now that CD recorders are no longer in demand), the alternative is the built-in Bluetooth transmitter - if indeed your have a device which also supports a Bluetooth feed.

Are there any software updates to use Dolby Atmos Height Virtualization or DTS Virtual X?

Asked by: Rafa
Hello Rafa, Unfortunately, the AVR-S660H is a five channel AV receiver. An AVR would need to be at least a seven channel AVR, and to already have other necessary components in it's circuitry to be able to offer Dolby Atmos or height virtualization. The AVR-S770H is suitably equipped for Dolby Atmos and DTS Virtual X. Here is a link with the details: https://www.denon.com/en-us/product/av-receivers/avr-s770h/300777-new.html

Would this receiver be enough power for the klipsch r 820f towers and the klipsch r41-c center? Both towers are 150 watt rms and my center is 100 watt rms all 8 ohms. Or should I go bigger?

Asked by: Dylans
Hello, The AVR-S660H will drive your Klipsch speakers and go quite loud, but if you have a room which isn't small, or if you like to crank the volume up beyond moderate levels, it is wirth considering, the further up our AVR line you go, the more control the AV receiver will have on your speakers. I suggest having a look at the AVR-X1800H (or the model it replaced - the AVR-X1700H while they are still around) as they have improved power supplies in the power amplifier stage.

What is the difference between this unit and a denon S560H?

Asked by: Keith06
Hello, The AVR-S560H is not a model in our catalog. If you mean the AVR-S570BT, the main difference is the AVR-S570BT is not a network AVR. This means is does not have a HEOS engine or support use with the internet either wired or wirelessly. Other differences include the AVR-S660H having support for 4 ohm speakers, Audyssey MultEQ auto set-up, HDR10+, Pure Direct mode,Bluetooth headphone transmission and two extra HDMI inputs.
