“Stunning! Using in a BHK PRE and i've rolled a number of 12AU7's, 6922's, 7308's, 6SN7 but all were lacking in some way. These tubes just opened up the sound and made the speakers disappear.”

“Still evaluating these tubes in the driver stage of my PrimaLuna EVO 300 Integrated. So far, so good. They seem very clean, good mid-range and improved clarity from stock. They should only get better with more use.”
