PPI Atom Amplifiers - High Tech, Palm Size

I don't read much on these amps, no reviews anywhere, do these Atom's do rated power?

Somewhere i read they are something like 95% efficient, (that seems amazing) so i would imagine they stay on the cool side. i was thinking running the A900.1 at 2ohms for a SI BM MKIV sub.

 
This is an online only product for us, so I have not tested either model. I have heard of no issues to speak of. If you have the space for it you would like JBL GTO-501EZ. I love that amp and its output is not in question. It's not listed on our store but I can add it.
