ATI makes a lot of amps for a lot of other brnad names.
They're an on shore left coast product. Good support. Good warranty. Sell well here preowned. Very good build from what i've seen and heard from othere's here. Been around for a long time too with a good rep.
I'm not sure how much of those comments can be aplied to Emotiva. Call Emotiva maybe and find out for yourself... BTW call ATI too.
