“In the confusing world of audio, especially higher end audio, hyperbole often rises to absurd levels. This makes it tough to ascertain what offerings are true gems and which shall we say fall short of gemstone quality. Having an honest broker in the midst of this maelstrom is for the potential customer and music lover such a rarity as to be unrecognized amidst all the sound and fury. Enter Upscale Audio. Kevin has been navigating these turbulent waters for many years. He has been savvy to vacuum tubes for at least as long as I have been aware of him and his activities going back decades. The Mullard GZ37/CV378 are nothing less than superb. Will there every be made a full wave rectifier that equals it? I don't think so.”

“I was immediately impressed with the huge audible difference between these tubes and my previous ones. Prior to installing these, I had been frustrated by the lack of bass and the narrow soundstage. With just a few hours on these Mullards, I could not believe the vast improvement from my Art Audio Jota amplifier. Midrange and treble are also more natural sounding. Don't deprive yourself of a wonderful musical experience like I did before I purchased these Mullards.”
