High efficiency speakers


I am looking for medium size high efficiency speakers. How would you compare trenner & friedl RA and Devore orangutan 0/96? Any others I Should be looking at that similar or smaller footprint and can be driven sufficiently by 8w 300b SET? Thanks

I heard Tanner & Friedl and Devore Orangutan in RMAF 2013 in different rooms.

Preferred the Devore Orangutan by a large margin. More resolving, more involving. Admittedly the electronics driving the two speakers were different and so were the rooms of course.

Hope that helps. I also preferred it to and Zu, Coincident (TV 2).

Just my two cents.
While not a fan of Daedalus loudspeakers, sonically, I've been around them enough to know they do play fine with 8 watt 300B SET amplifiers.
