But if I had to say, those amps that you try to turn up to get them to play ball have too little feedback (20dB isn't near enough), with no way to add the amount needed to get them around that problem.
Sounding loud and sounding dynamic are not the same perceptually.
Yes and no... both come from higher ordered harmonics. Music has a lot of transients- that's where the power usually is needed. In an SET, when these transients occur, if they happen at a power level where the amp's linearity is reduced (usually about 20-25% and above) then the higher orders show up on the transients and nowhere else. That makes them sound dynamic. At higher levels though it becomes 'loud'. This is why so many SET owners seem to think that 85dB is all the 'louder' they need.
Not sure what you're referring to in your first statement. I googled Peter's name but don't know what I'm looking for. Do you have a link?
When you get rid of that issue, you can't even tell that they system is playing that loud. Now the dynamic structure is coming from the recording rather than the electronics. When sitting right next to someone, you may find you have to yell to be overheard. IOW, its lot harder to tell how loud the stereo is playing.
