“After one of my previous Brimars went bad I put all my previous tube experiments back into Rogue Sphinx v3 and nope, I knew I needed 3more, one to replace the previous one and a backup pair. Beautiful! So thanks Kevin I’m a happy customer. Break out some more 12AU7s man!”

“I love the Brimar tubes in my Rogue Pharaoh amp. I believe the cryo treatment provides a crisper, more defined sound.”

“I upgraded the stock JJ’s 12au7 tubes with these in my Rogue Audio Sphinx V3. They made a huge difference. Much cleaner sounding and warm now.”
