apparently made to higher specs



If you look at the specs for the Outlaw 7500 and the ATI 2000, they are identical, right down to weight. You have to wonder what Outlaw gave up to get the price down, but if it was the electronics, then the specs wouldn't match up.

The ATI 2002 amp is the same cage and toroids as the 2007 amp. They add modules for channels, but not the toroids. Additional channels only take a share of the power of the toroids.
