Plinius SB-301. thoughts and opinions?

very little info and only a few reviews on these amps out there. most of what's out there seems to be cookie cutter press release info. anyone have any experience or thoughts on this thing?.

general comments welcome but specifically....how are they at driving difficult speakers (Aerial 7B's). i do understand that they don't quit double down but can't find any detailed info otherwise.

any input from owners or those with experience would be appreciated.

thanks
Lev.
