While you are merely being empirical, there are actually plenty of devices that aim to "benefit" the end sound of SS gain by using tubes to "condition" the signal from DACs, etc.  Also, there are plenty of commercial widgets out there that say they will bring the glorious "Tube Sound" to a given system.  I have to say, I regard this stuff as basically soft-headed, and results I have heard literally speak for themselves. Who wants to "listen to tubes"?

OTOH, the injection of 2nd order harmonics is a well-known "remedy" for the typicall hi-fi "Upward Trend", not to mention the fact that LF is really a different animal in terms of getting it to "work" with the rest of a system in a given listening area, and I'm all for reverse engineering according to what "works", sonically, no matter what the experts say.

I was thinking myself what I was attracted in my ULF with tube crossover was just a simple “tube sound”. They I realizes that there is something more to it. To relive my retaliation you need to ask yourself: what would constitute “tube sound under” 25Hz? When I realized that there is nothing that I know about “tube sound” in ULF region then I stopped to look at the problem as “tube sound” and begin to look at it as sound in the tubes.

What I find interesting is that there is nothing in that sound of my tube ULF that I like for it specific “tubbiness”. It is rather that sound ULF is better integrated with the sound of my playback and the ULF has less some negative elements of sound that I explicitly noted when use SS amp/ BTW, I did not feel that my installation demonstrate “tube sound”…

That all bring me to think that if my little tube crossover did such a pleasant job with my ULF them how great would it be if the ULF would be coming from a powerful SET that would not need any 4 stages of active crossovering….
