I am out of town for the Holiday and staying with relatives. There is an audio store a few minutes from my relatives and I stopped in yesterday and was starting to listen to the new Denon when after 5 minutes I was called away for a family emergency. I was impressed by the little audition, and don’t think that you would be unhappy if you purchased it. I have a previous version of this player which I should sell off (I changed to using an Oppo 105 outputting to a DAC that has HDMI inputs) but the new player seems to sound tighter with more focused bass.
I haven’t heard the Ruby but Marantz players also seem to sound good in the midrange (where most music lives) but roll off the treble.
