Merlin TSM with Shindo 25 watt amp

a, since i do not know you or your listening habits, i can only offer that i use a 20 watt ss class a amp in my livigroom. it is plenty for me in a 14 x 24 x 10 foot room. this is 3360 cubics and fairly large.
rob says they work well with his amp in his room and mitchell says no. he used the vsm's which are more efficient and room filling and he was in a smaller room. no one is going to be able to advise on this because it is very personal.
for as many that use 12 watts and say it is fine for them, there are people with 40 that say its too little.
good luck.

a, the 30 watt tube guideline was made 15 years ago and was relative to the products available at that time. today there are many lower powered tube amps that drive them very well. i should change the specification.
i use a fila which is 22 watts pure class a in a 8000 cubic foot room at the factory and it sounds imho, room filling and right. remember that the tsm is imp eq-ed and runs at 6.5 to 9 ohms which is very tube friendly.
nuff said by me.
best, b

It will be just fine unless your a banger,YMMV,Bob

FWIW, I am running my TSM's in a 16 x 13 x 8 room with a pair of Manley Mahi monoblocks. I never take 'em out of triode mode (20 watts/channel) and they play PLENTY loud for me! I've tried them in UL mode (40 watts/channel) and I miss that glorious triode midrange. Yes, it's a matter of taste, but in a medium small room, they'll go plenty loud on 20 watts.
