I have a S&B TVC, agree with Ozzy62, and find the passives lack of perception is more like passives dont add dynamics, colorations, etc. of active pres.
Compared to running direct - the TVC adds a tube like liquid, warm feeling in the mids, the highs smoother or slightly rounded, and pace more relaxed. The alteration are very, very slight, and much less than the actives Ive tried, but not absolutely invisable either. Everything else seems untouched.
I havent compared it to many actives and would be interested in comparisons from others like Ramses.
