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.

Uiterst snelle levering. Laat op de dag besteld en volgende dag al geleverd.

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.
