“The sound I've been looking for. Not sure how tubes do their thing, but this tube is a leap above anything else I've tried. NS Telefunken, Mullard, JJ and NOS Mazda. Just great dynamics and insight to details. No regrets due to price. It's like adding or upgraded a component. Rogue Perseus Magnum.”

“Back up pair. Triode balance on one tube was 8.8 and 11.4 which I’m not thrilled about. Sounds fine though and I guess that’s what matters.”

“These sound super rich with tight bass and smooth highs. I’m still breaking them in, but I noticed a difference right away. Great tubes”

“I use these in the 2 middle locations in my Prima Luna EVO 400. They are such an improvement I ordered a small stash as back up.”
