“Running them in my vintage VTL preamp. Expensive and worth it. Thanks, Kevin.”

“Maybe it’s psychosomatic, but the tubes sound incrementally better I don’t care if it’s in my head because the improvement was that gpid”

“These Mullards gave my Octave integrated tube amplifier a definite enhancement in the pre amp section; I can hear an improved musicality in the upper end and midtones. Great tubes!”

“In a word, spectacular! I think I've finally found a keeper for my V1/V5 slots. Amazing clarity, huge soundstage with awesome 3D. Pink Floyd is playing live in my listening room right now. The realism is unmatched. I've been through a boatload of preamp tubes including NOS but none of them come close to matching the Mullard CV4004. Thanks Kevin!”
