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. |
