Some would argue that it is all speaker dependant. I have found there is definitely a point where more available power does not improve the sound any and you begin to look to other areas for change/adjustment. THat being siad, for most folks using multiways speakers, a 100W Class A amp is not too much, especially when considering the transient needs of such setups. I think it large comes down to ease of presentation of music. Once you get to a point where you do not feel increasing the power is changing this, you probably are in a good spot.

I suspect that with most speakers and most listening conditions in most houses, that peak output voltage is not a problem. I think we may more often distort the waveform due to current clipping, particularly if our peak to average overhead is maintained around the 20dB range.
50W into 8ohms, but feeding a 4ohms speaker, can require transient currents approaching 30Apk. Not many 50W amplifiers can maintain drive voltage while delivering 30Apk. That's what I see as the problem at "sensible" levels.

Playing loud and well into voltage clipping is a different ball game.

I may not like them either, dunno yet, but there is something attractive about having that kinda dynamic swing available. I am looking forward to your build

I currently have standard 2-way floorstanders that is rated at 89db. My KSA50 can drive those at levels that hurts my ears. I however have been eyeing the Troels Gravesen DTQWT Mark II design. My room is 5 by 4 meters.

Sorry for OT.

Would It be silly to ask you henryve to compare your KSA50 to the F5t
Not with what sounds better or worse but the differences ?

Still need to get the transformer and heatsinks for the F5T, so it might be a while.
