In F7 manual, Nelson says, “Most of your “better” amplifiers have higher damping factors like 20 or 100”. Augspurger and JL Murphy also concluded damping factor of around 20 is just adequate.

But Nelson also says “You could argue that single-ended tube amplifiers sound good and don't have much damping factor, and you would be right”, and he is talking about SIT amp with damping factor of 1 or 2.
In my experience, I can agree with the statement saying DP=20 or 100 is high enough, but since I don’t have any experience with low DF amp like SIT, I would like to know how the lowish damping factor would "really" affect the bass response (or if it doesn’t matter at all, or does matter significantly depends on music genre, playback level, speaker unit, room, taste, etc.).
The reason why I’m asking this is I’m planning to build L’SIT SE tri-amp (high, mid, low, active crossover). It’s theoretically safer to have higher DF amp for the woofer, but I would like to challenge all SIT SE system if there is no significant drawback.
