Feedback received via email from customer Lincoln W.:

“Hi Rachel, I thought I’d give you a preliminary feedback on the Treasure Globe 6SN7-SE.  they are simply amazing. A pair makes the entire system sound like a brand new system! stunning life -live -like music. HUGE soundstage. I’m running a DAC that already made the soundstage big, but the tubes gave it more depth, the soundstage became bigger.  lots of air, lots of presence…the music produced was jaw dropping – arms up in the air moments. and there were many!”

(note: Lincoln uses 6SN7SE in a Supratek preamplifier)
