You can expect to get excellent sound from this little receiver, but don't expect to crank it up high, it wasn't built for that. For that you will want to add an external amplifier.I did this, and the difference is night and day-more power and headroom, this in my opinion is the way to go. Overall this unit is a gem

The sound is magnificent, but it strongly depends on the speakers used. So, do not expect too much if you will use low quality speakers. I have two Focals and Onkyo subwoofer and it is great. The CR612 in addition to being a network streaming device, has also a CD player and this was a big plus for me.

The user interface is difficult to use and the quick start guide provides little help other than basic setup instructions. If you want to set up anything beyond the basics, you must find the full manual on line and read through it to complete anything more than the basic setup.
I connected my Pandora account but the HEOS application does not recognize that I have a paid account so it does not let me skip an unlimited number of songs.
To reconnect a Bluetooth device whose name had changed, I had to unplug and plug in the MCR612 to get it to reset the Bluetooth connection.
Good unit, but nothing special about it.

As far as sound quality goes I am more than happy. This little music player was replacing much larger(more exspensive) amplifier, but so far I have not noticed a lack in sound quality or lack of power.
I am very happy I purchased the Marantz Cr612.

Now the fantastic part. Feature packed! CD player sounds amazing via my Senn's and B&O headphones (no speaker yet, remember ?) Nice ambient lighting options which was a nice surprise. Micro adjustments for sound i.e bass, treble etc. Lots of options for streaming audio thru internet, Alexa and other providers. Fairly easy setup but use the online manual! The guide provided is VERY basic.
