Demon customer agents have been easy to contact and very helpful!

The technical service I got from Jamar was outstanding!!!

Prompt delivery and well packaged!

This Denon replaced a dead Onkyo system and as soon as I got it hooked up, I could hear a difference. I'm no audiophile by any means but the sound was noticeably better. Then after I did the Audyssey calibration it was even better.

Great

Great price. Fast shipping.

If I didn't know this was a refurb product it looks and plays like brand new. Will certainly consider Denon! refurb in the future. Highly recommended .

Shipping was amazingly fast

Bbeautifully packaged, super quick shipping; perfect!

It's a refurbished unit so there's that. . . . . I'll take my chances but it all started on wrong foot! Got it all hooked up, loaded batteries into remote and fired it up--------but nothing happened! Swapped out to American batteries and still NOTHING! After significant diagnoses, called CS, explained problem, answered many questions and they offered to send a new remote. Got it a week later and NOW, I can finally enjoy this receivers benefits. Sadly, Denon chose NOT to provide an operating manual and CS suggested that I print one from the website_____147 pages! INK is expensive

amazing sound

Very easy set up for the speaker arrangement I decided on. (7. 1 Atmos). Easy selection of sound dynamics. The receiver synced with the Samsung TV remote. I am still determining the best sound for what I watch on the TV. The Audrey sound set up makes it easy to set the perfect sound as to where I seat in my Theater room.

Well packaged and arrived on time.

Flawless and quite fast to my region for delivery,

Shipping was very prompt.

Just great quality. I can trust Denon.

cost, ease of use ,sound great!

GREAT, I HAD A AVR S660H FOR SEVERAL YEARS IT WORKED WONDERFULL UNTIL A LIGHTNIG STORM GOT IT. THIS S770H IS A GREAT REPLACEMENT. SPECIAL THANKS TO ANDY! THANKS FOR EVERTHING.

I had a very good experience with Denon. I bought an another product just weeks after i purchased this one.

Everything was great. The purchasing options, shipping, everything.
