When you get this all hooked up make sure you have seat belts on your couch your in for some serious high octane audio.

Yeah, they are fantastic amps - and incredible value for money - its certainly a big benefit buying direct from the manufacturer. I thought they would be perfect for the Aerials - massive current, high damping factor, and incredibly low noise floor (124dB on the monoblocs).
AB Systems, and Bob, the owner, are great to deal with. I loved the fact that I could specify various components and designs myself - I had SE versions, and had them all with Teflon V-Caps throughout, and Clarity caps on the power supply, plus pure silver wiring throughout. They are not the best looking amps out there, but it is somehow reassuring that all the production costs go into the internal components rather than fancy casework.
There is an extensive thread on them on AVForum - have a look at page 28 as I have posted quite a few pics of the amps:

Yes, AB Amps are used in quite a high level pro-studios as you have listed. They also manufacture the internals for quite a few brand name manufacturers I believe - they used to make the amps for Cinepro, which were based on a similar design to the current amps.
