I think your current AVR or similar (300 Watts x 2Ch into 4 ohms continuous) is good enough.
If there is any chance you will be getting a Pre-pro or AVR that has XLR outputs, then I would get an amp that has XLR inputs.
AFAIK, the Yamaha RX-A3080 is the only current AVR in the world that has XLR outputs for front L/R.
If none of the above, then it doesn’t matter if the amp has XLR or not.
As for Emotiva, Gene has “quit“ Emotiva and so have many of us. Like we have “quit” cable.
I wouldn’t touch EMO with a 10-foot pole.
If you want more budget brands, Outlaw and Monolith are options.
But if my SVT towers were SVTR with internal XO for the SV-1212NR, I would still just use my Yamaha RX-A3080 AVR w/o using any other amps. And I sit 18FT away from my speakers.
Your HK-7200 AVR should have similar power to my RX-A3080 (300 Watts x 2Ch 4-ohm).
How far do you sit from your SVTR?
