    Excellent Refurbished AV Receiver That Sounds Amazing

    This Denon AVR-S670H Refurbished network receiver is incredible. It produces extremely clear and crisp sound at all ranges. It was delivered a couple days early and arrived packaged extremely well in perfect shape. I just did the manual audio setup and it sounds amazing and was really fast. I have 4 awesome in-wall Polk speakers and a very nice Klipsch center channel speaker. They all sound wonderful together. Donated my Klipsch subwoofer. It took up too much room and not really into the "big boom" nowadays. The Klipsch center channel and the two front Polk's carry a decent amount of low end so the bass sounds pretty good without a subwoofer. I use a cat 8 network cable from my high speed Wireless Router's ethernet port to the Denon network port just to keep things simple. I prefer direct wired connectivity to my AV receiver. I mostly just use "Internet Radio" on my new Denon. My favorite Internet Radio Classical station sounds incredible. It sounds so good you would think the Concert Hall is in my living room. Also, I use the Tuner and occasionally eARC with our new 4K TV. The HDMI eARC connectivity and sound is fantastic from the TV to the eARC port on my Denon receiver. Also, the receiver looks practically new with a very minor tiny scratch in the back that is almost not noticeable. The remote looked new, but either way new or used the remote works beautifully with this nice refurbished Denon receiver. Highly recommend Denon for purchasing directly from Denon. com and this excellent 5 channel receiver.

    Great amp poor directions

    I had a Denon 5. 2 amp for 20 yrs worked great. It stopped working so I bought this amp. I love all the bells and whistles that it can do but I can access them. I used the optical sound and connected the hdmi to the right arc port. I says tv is connected but I get no on tv set up and it didn't come with a user manual.

    Very Happy with Purchase

    A bit skeptical of refurbished, but decided to put my chips down. Totally happy with the condition of the unit, no noticeable scratches or other defects. All parts were present. Packaged very well. A couple cues that it was not factory fresh, but nothing that affected form or function. Movie sound processing on my 5. 1 system is excellent. Was a good purchase to pair with my new Sony 4K TV (finally!).

    Great Unit

    I purchased the Denon AVR-S670H for a living room setup. After installing the software updates and power cycling the unit to get CEC to work correctly, it's been a perfect unit for my 5.1 setup with TCL google TV. I did buy this unit when it was on sale.

    Refurbished, yet perfect!

    The S670H arrived on schedule and was like new in every way. Set-up assistance was easier than expected. The unit restored my home theater to its natural state. I couldn't be happier and can confidently recommend Denon Refurbished to anyone looking for top quality at a cool discount!

    Awesome price, awesome sound

    Refurbished, it's powering a 15 inch reference subwoofer and Klipsch front and center speakers. The sound is amazing. I am very happy

    A Nice Upgrade

    Had a soundbar for 8 years. Remodeled my LR and a Denon receiver was recommended by a high end home theater business. My job was too small for them! But they knew their stuff. This unit sounds great! And running separate center, left, right, and subwoofer Atlantic Technology speakers drastically increased the experience of my home theater. FYI- I was a sound recording engineer back in the 80's and 90's.

    A fine receiver but no Alexa connection?

    Very good receiver for a reasonable price. Lots of features that iI like and the set up process is very user friendly. However, I miss any description about how to connect the receiver to my Alexa system. Does it even exist?
