The processing technology of the surround signal in the Sony is better vs 10 yr old Emotiva technology. Sound is more open & distinct in each channel.
There's nothing wrong with XPA (gen 2) amps, they're a very good value buy & I would buy another if needed, especially if I could find a new XPA 1L or SA250, two of their best sounding amps for the $. XPA amps have very good speaker driver control, no slop, nothing "dirty".
As far as XMC-1, 2-ch balanced circuity playing music, good luck finding better, there's nothing "dirty" about them.
Sold an Anthem AVM60 b/c they're a little too bright for me & it didn't surpass the XMC Burr-Brown dacs.
Audio is all about component matching within the system, especially the speakers, which mine have been & still are Monitor Audio.
