About a year ago I've replaced an 706 Onkyo with old known hdmi bar crap, for an Yamaha 2020.
The first impression was about the speakers, Jamo Concert 607 for fronts and the same brand for the rest, in a 550 sq ft living room, which was very appropriate for the Onkyo, but a little bit small for the Yamaha.
In a bad comparison, I've changed a GM Equinox for a Lambo Urus.
Maybe I'll never have a chance to really test it.
I need to tell you that I have a lack of words to describe it.
The only thing that I'm confident to tell you is that I can listen to the diference between the records even more. Good mixing on CDs, DVDs and BDs are awesome, but if not that much, what was listening bearable becomes almost annoying.
Once that I can't release all the power without crash a window or having a neighbour ringing at my door, I suggest a visit to a distributor for your own impressions.
All the best
