“I wrote a review after 25 hours which you did not print.As i said, so far the silence is impressive, vocals are disappointing[though this may be too soon for an accurate evaluation, as I have plans for a 50 hour review.]Classical recordings are frustratingly varied in quality.It's difficult to nail down the fault for good and poor ones:: the recording engineer or the tubes. I think it's the engineer in most cases.But I do find transparency improved.”

“Bought as a less expensive backup to Brimars. Reall like the cooler crisp quiet sound of the GEs”

“My system is Goldenear triton 7 speakers powered by a Primaluna Dialogue Premium integrated with Tung Sol EL34 power tubes and stock driver tubes. This tube adds clarity and resolution over the stock tubes in the most natural and musically way. Everything just sound more realistic. Before installing these tubes I found myself listening in triode mode more often then ultra linear, now it’s the opposite. Love Upscale Audio, this store is a true gem. Every experience has been flawless.”
