Phono preamp tube rolling.

As upgrade rush bites again, planning to perform some tube rolling on my Rouge Ares Magnum. Please share some experience with tube rolling on pure tube circuit topology phono preamps. Practical experiences are preferred. Theoretical options are welcome too.

Mullard Blackburn longplates are very good. I also like the CV4003 boxplates, although the 12AU7 long plate square getter and large O-getter are cleaner sounding with excellent imaging.

I love the Brimar CV4003 boxplates, similar but more  transparent than Mullard with very good highs.

For phonostage I mostly used 1950's RCA black plates. Not as warm as Mullard. More transparent with great dynamics. Need to request low-noise.

By the chance, did anybody tried Japanese stuff? ….Hitachi 12AX7, NEC 12AU7, Toshiba 12AX7 or Matsushita 12AX7 ?
