Rogue Sphinx or Belles Aria???

I've recently been building up my system over the past year getting into the mid/hi-fi level and have finally reached the point of upgrading my amplifier [currently older Yamaha A-S500]. 
I'm looking for an integrated amp in the ~$2k range [I don't have space or budget for separates] and think I finally have it narrowed down between a Rogue Sphinx v3 and a Belles Aria.  I'm only listening to vinyl so have no need to worry about a DAC.

The Rogue has many positive reviews so think it would be a pretty safe bet and while I can only find one professional Belles Aria reviews the personal reviews in various forums seem to be pretty spectacular and seems to punch above its class so I'm really intrigued. 
Unfortunately, I'm not in the position to demo either of these personally so I'm looking for advice; especially if any one has ever compared side by side.

The rest of my setup is as follows:
B&W 705 stand-mounts
Rega Planar P3 w/ Elys MM
Audioquest Sydney interconnects

I really appreciate any advice...thanks!
