I am a tube guy, so I thought I wanted the TL version, but I'm also a detail guy, so I decided on the HS version after hearing that it was not harsh (which is usually the trade-off you have to put up with if you like details). I can't handle too much upper midrange, but the HS does not accentuate that , so I'm happy with my purchase. I'd sure like to hear a TL version someday to hear what I'm missing. I may get one once I get my upgrade on the Ultra paid off and my remodel finished. Also, I'm using an old Njoe Tjoeb 4000 tubed CD player which has a SPDIF out.
