When I needed to replace the tubes in my Phono Preamp, I called the manufacturer, Zesto. Fortunately, they are a small to mid-sized manufacture and the owner/designer/salesman, George, is a wonderful guy who loves to speak with audiophiles.
He told me that he listened to many new and several NOS sets of tubes when voicing my Andros 1.2. His choice for the 'Best Sounding' tube was current production (and inexpensive) JJs gold.
You may want to contact your gear's manufacturer... like George at Zesto, they probably have done their homework!
@ larryi, thanks for the information on Tele-fakes. Perhaps this is why so many folks are reporting that modern-production tubes, of various brands, sound as-good or better-than NOS tubes.
