Denon AVR-S670H 5 2 Ch Home Theater Receiver 8K UHD HDMI Receiver 75W x 5 Streaming via Built-in

I traded up to a Denon AVR-S970H from an Onkyo TX-NR636 that was slowly dying. They have mostly the same power rating and features. The setup was fairly straightforward with a few little quirks that, until you understand the operating logic, are common when you change brands. This receiver is advertised as a 7.2 channel system. It also advertises a powered Zone 2 output. However, you can't have both at the same time. The powered Zone 2 outputs use re-assigned Back speaker connections and the system then becomes a 5.2 system. Since a 5.1 and powered Zone 2 is what I already have, this fit my needs exactly. If you want a 7.2 channel with powered Zone 2, this receiver can't do that. Most of the new 7.2 systems seem to have a separate pre-amp Zone 2 output, which requires either an additional external amplifier or powered speakers to drive the Zone 2 sound. The use of their HEOS app to access on-line music streaming is definitely different, but seems to work ok. The additional Denon Remote app operates the receiver via Wi-Fi, which also works ok. Nothing fancy, though. The Bluetooth transmitter isn't available for wireless headset use when either the MAIN Zone or ZONE2 are sourced by HEOS, which prevents you from streaming on-line music from the receiver. TV Audio, Blue Ray, USB, CDs, etc. can all still be Bluetooth'd out, just not a HEOS source. I was stumped about this issue and called tech support. They answered the phone immediately and quickly answered my question. Not the answer I wanted, but that's how it works. If your TV or Blue Ray player can stream Pandora, Spotify, etc. app, you can feed that to the receiver and Bluetooth it out to headsets, so there is a work-around. The sound quality is very good and is marginally better than my old Onkyo. The Denon has some audio tuning features not on the Onkyo (Dynamic EQ, Dynamic volume, MP3 Rendering, and others). I have a remote reading temperature sensor in my stereo cabinet. The cabinet with an Onkyo always ran about 90-92dF. This is fairly hot and can impact long term reliability. To limit that high temperature, I had added 4 little computer fans to help ventilate the cabinet. So far, the highest temperature I've seen the Denon run is 80dF, a big difference for the same sound volume. Not sure why that is, but I like the result. I can probably remove the cooling fans. The one thing I wish the Denon had is a programmable TV power button on the remote. This missing feature forces me to use a 2nd remote every time I turn the system on. Overall, I would definitely recommend this receiver to anyone looking to buy in this price range. Read more

Denon makes great audio equipment, and this Denon AVR-S570BT is no exception. After 12+ years of daily, faithful use, my Pioneer AV receiver bit the dust. I researched many quality "budget" AV receivers (to make the wife happy...lol), to replace the Pioneer receiver, and a lot of reviews and recommendations came up with the Denon AVR-S570BT. This Denon AV receiver is very intuitive, and easy to setup. It also has a LOT of features in this lower price range. This Denon AV receiver powers all 5 of the passive, original Pioneer Andrew Jones Design speakers (the subwoofer is self-powered) in my 5.1 surround system very well, and with great clarity. No, this Denon AV receiver won't blow the roof off the house, but it does get very loud, even with inefficient speakers, as the Pioneer speakers are, with an 84 db to 87 db sensitivity rating. However, the Pioneer speakers are 6 ohm, so that helps to increase this Denon AV receiver to 90 watts per channel, instead of 70 watts per channel at 8 ohms. This Denon AV receiver also seems to run a lot cooler than the Pioneer receiver it replaced, especially at higher volumes. This Denon AV receiver has just enough "bells and whistles" for my needs, as I really don't need 7.2 surround capability, Dolby Atmos, or WiFi features that come with the more expensive Denon AV receivers. Although, the included Bluetooth connection does come in handy, and it works very well with Samsung Galaxy Smart Phones. The automatic speaker calibration and setup is pretty accurate, but it also allows tweaking to individual sound tastes. There are probably features and modes of this Denon AV receiver that I will never use, but it's nice to know they are included just in case I need them. Overall, I highly recommend this Denon AVR-S570BT for anyone that is looking for a high-quality "budget" AV receiver. Just know that it does not have all of the newest features of some of the more expensive Denon (and other brand) AV receivers. However, this Denon AV receiver serves its purpose for me quite well, and then some. Only time will tell regarding durability and longevity. However, Denon does make quality AV receivers, and if I can get the 12 years out of this Denon AV receiver that I did out of my previous Pioneer AV receiver, I will be a very happy camper. So-far-so-good, though. Read more
