Denis- For moderate levels, I found that a 9wpc SET 300b amp drove my 89 db Merlins just fine in a 14 x 23 x 8 room. You should be fine.
Will Push-Pull Triode amp 20-25 WPC work?
I own a second generation pair of Allison 4 speakers, (2002) which are pristine. The room is 12 X 12, quiet to moderate sound levels, mostly classical, occasional jazz, Speaker sensitivity 87 db, 8 ohms. Can I get away with a triode amp (that I really want), like a 300B, putting out 22-25 WPC? And no, I dont want to change the speakers for 100 db sensitive ones, as I know I should, as these speakers work perfectly in the room, in my office, against the front wall, and are probably the best speakers Roy Allison made.
