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.

@lowrider57 Sorry, I’m not really interested in suggestions based on my components or system analysis. What is really interested  is other people experience in the topic. 
OK then. Phono preamp is an extension of cart, arm, table. I'm sure you will be asked this question again.



In general, I am not a fan of tube rolling.  Listener bias makes it almost certain that you will be certain you hear differences right away.  (Because you spent money on the new tubes.) But those impressions tend to fade over time, unless you are replacing truly worn out tubes, in which case you will inevitably love any fresh tubes. Given the fact you have supplied no further information, that is about the extent of any response I can conjure.

Totally agreed with first part of your statement, but no offence, I’m pretty sure I will not ask any questions, cause I like my own experiments and conclusions. Just wanted to hear other people experience.
