Excellent Solid State or Hybrid Monoblocks Recommendations

@big_greg the mods were extensive. I will look up the email that detailed them and post later. The mods took it well above its stock performance.

@ hilde I sold the Spatials recently so they are no longer in my stereo graveyard.

@ tvad I appreciate the amp recommendations and will do my due diligence on them.  I suspect that I drank the Kool aid about believing higher powered amps sound better than lower powered ones of similar quality.  Good to get the experienced input on this topic of "not so fast".....i have modded a lot of my equipment, however, I am willing to go higher up the food chain to get the type of performance I want sans mods

@tvad haven’t seen you around the forums in ages! Hope you’re doing well!!!

@jaymark why not fix the parasound amp if you like the sound? 

Have you looked into PS Audio's hybrid amps?  I have a BHK 250 that sounds excellent with Scansonic MB3.5s, which have similar requirements as your Aerial Acoustics.  The BHK 250 is on clearance now for ~$4k on PS Audio's site and a steal at its current price.  There were also a used pair of BHK 300s that sold in the $6k range recently, so may be worth keeping an eye out for if you're set on going the mono route.

The 6922 tube and its variants in the BHK 250 are fairly low maintenance, long-lasting and not too expensive unless you get into the rare and exotic tubes.  I've had great results upgrading to Acme's silver fuses and tube rolling.  I really like the ability to alter the amp's voicing, which may also appeal to you.
