IF you have a great deal on the ATI6005, you may want to check it out! But you also have the choice of going QUAD XPA-1 gen 2! I would select that choice (if you have tons of cash).

That ATI amp is very heavy haha, two of the new XPA DR1 amps may be a nice way to go, the new reference monoblock, my Sherbourn PA 7-350 weighs 99lbs and it wasn't fun putting it in my rack by myself lol.
