Excellent Solid State or Hybrid Monoblocks Recommendations

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.

Used Pass XA160.8 mono blocks come in under your price...

@audphile1 I am going to get the JC1 repaired. You are correct. I have too much money sunk into them and the mods to just walk away from them. They also sound stunningly good. Just a good excuse to pick up another amp for my rotation and/or backup.

@jaymark thank you.  Feel free to PM if that's better.  

@pynkfloydd I will check out the amps u suggested on the PS Audio website.

@jl35 Thanks foe the PassLabs suggestion. I already have two Pass Labs amps, neither though is a monoblock. They sound good, both modded, but the JC1 monoblocks sound better, especially in the upper registers.
