Finally read the Low Wattage guidelines and am surprised at the 25 watt limit (to "work well" and sound "moderately loud").Grandma says anything over 75 dB is loud, so I'm not sure what the guideline really means, but don't want to get into an endless debate over it either. And 25 watt limit opens the door to most tube amps, including virtually every push-pull amp in triode mode.Anyway, my system does/doesn't qualify. Just picked up a new tube amp (review forthcoming) that qualifies in triode mode and sounds fine with my "babies" (promise to post something on them in the speaker thread) and in fact haven't cranked it up all the way to see how loud it does get. OTOH I have 100 watt digital mono blocks that also sound good (as good as depending on the tubes used). Used to have a 7 wpc battery powered tripath that worked well, sounded moderately loud, and kicked some SET butt in terms of handling my speakers.
Gee, I could easily make a 25W/Ch version of our SET 120 amp and do it for about $499.It would be unbreakable as the output transistors would be working at a tiny fraction of their capability.Fully regulated power supplies and dead silent.Anyone interested?Frank Van Alstine
Yes, I could bias a SET 50 on full Class A if somebody wanted that.Frank
