The best of a tube sound without the negative lag and boominess that some may have.
by Tony
The original tubes on this amp where very noisy. The upgrade is night and day. When I turn up the volume there is no hissing sounds...
Compared to more expensive Millard's: Tighter faster bass, precise instrument separation, and clear and defined highs, but not bright at all. Feels neutral.
The first big difference the bass is fast, tight , and textured.
Great soundstage.
This is a tube for someone who wants neutrality and a quick response, not a warm sounding tube.
Worth every penny.
Great customer service too!!!
Rogue Audio Sphinx Magic!

Shopping by Amp I chose this Ultimate Package for the Rogue Sphinx and OMG! I can't believe how good these tubes sound after just installing them and they seem to be getting better by the hour. I'm an impatient type of person and have tried a number of tubes that didn't seem to improve, even after a week of break-in, but these sounded extraordinary out of the box. I can't even imagine what they will sound like after burning in! You folks know what you're doing!
