“These sound just lovely. Better than the replacements I purchased from ARC for an LS25 mkII. Thank you, Kevin!”

“Came well-packaged with all test specs on each tube and bundled by matched sets. Haven't installed yet but hopeful they sound equal or better than OEM tubes.”

“The cryo-treated 6H30 tubes transformed my preamp (ARC Anniversary 40) into a dynamic brawler with finesse. This pre was always a powerhouse with its separate power supply, but now it can make a Steinway Concert Grand materialize full frame.”
