Building the Audio Note Kit 1 SET amp...

Reb I am tempted to just send you my triangle Titus xl speakers. They might be all you need I your room the fit the bill in our sunroom as seen in my system pic. I have a vision of running them off a set or similar tube amp someday.

Anyone ever heard these on a set that could comment?

It is funny to me that only insane audiophiles like us could get so bent out of shape over less than stellar bass with some pop music recordings. My system rules with that kind of sound. It would drive me nuts to lose the ability to deliver it properly. If I didn't know better I would not care. Ignorance can be bliss!😯

"The issue is the contraction and constriction of dynamics that come way before clipping."

I couldn't agree with this more and it has been my consistent impression in vast majority if not all systems using SET amplifiers. I've heard exactly two that overcame these limitations and they were both large horn systems. The real issue as best I can tell is that in most cases they are used with speakers that are WAY lacking sufficient efficiency to overcome these limitations. The bottom line is that this fact is overlooked by those that love the magic that they provide in the midrange. So in the end it is a question of what you can live with or what you can't live without. I still believe that in this case Rebbi should explore the options with the amp based on his committment and investment.

Yep limited dynamics prior to clipping is exactly what I am talking about regarding set demos that sounded ok but not great. It is like having a Ferrari and never topping 60 mph. That's the trade off I see repeatedly with just a few watts except with very high efficiency horns capable of picking up the slack.

It's about power and glory in music as opposed to beauty. I want it all!

Tube amps do soft clip which will limit the dynamics well before any clear distortion is heard. Soft clipping works well to preserve the beauty in music but also limits the impact and glory while still letting the music play. Great for acoustic music. Bad for electronica. IMHO.
