it's all about matching amps to speakers. plenty of people try and use underpowered amps on speakers and then figure it out at some point. the problem is the metric used is the "i can turn the volume up to X even" or "volume at Y% on the control is really loud" which is 100% fallacy.
i'd also add that underpowered tubes may sound "musical" but really people are just hearing more 2nd harmonic distortion at higher wattage levels. totally wrong.
effortless sound is the goal. it's not a volume control setting. it's the shove that Fremer said was missing on the big Vacs.
Yeah when I told Brad the KR integrated was constrained on the acoustats, he told me I must be listening too loud. I never got that. The much more powerful project sphinx, a hybrid, was so much better. I see this the speaker is 85 db the amp is 20 watts so add 85 plus 20 = 105 you should be fine kind of argument too many times.
