[QUOTE="zako, post: 7987703, member: 629735"] These are good amplifiers for the money.

What you need to know about them is that they're very small, efficient (run cool), and do their rated power. In fact, it is mentioned on that discussion by Grizz Archer (then PPI insider) that P1000.1 was underrated by an accident and they didn't bother changing the rating because literature was already printed.
