“Night and day difference on the driver tube positions (PL EVO 400i). Thanks Kevin for these perfectly tweaked tubes!”

“I used them to upgrade the tubes I'm my Primaluna DAC, they seem to be doing a good job”

“Started out with 2 in the central positions of Prima Luna power amp, which completely changed the sonic character of the amp for the better. Added 4 more when one of the OEM tube started to get noisy. The impact to sound is much more subtle, primarily a reduction in background noise.”

“Stunning improvement over the JJ stock tubes in my Odyssey Candela preamplifier. I have Khartago monoblocks and Kismet floorstanding speakers. Finally I hear why Klaus B. at Odyssey raves about those beryllium tweeters and sliced cone drivers; synergy in spades!”

“Using these tubes in my pre-amp. The previous tubes were Ratheyon and had a touch of flabby bass and lushness but enough detail. The GE’s have a nicer midrange but still have extended bass. They keep sounding better the more I listen. Very nice tubes.”
