Just ordered my 2EX upgrade kits for my Sierra 1s. Happy day!

I have a Denon X4200W and would like to drive the Sierra 2EXs a little better for music. Also will be running a Sierra Horizon Center with Raal, CBM-170 SE surround, and Imagine XA Atmos speakers in a 5.2.2 setup.

I'm looking at the Parasound NewClassic 2125v2. Anyone running one of these?
