Turntable consultation


Hello friends, and thank you for help.

I would like to have your opinion regarding improving the SQ of my turntable. Since I haven't listen to other brands except mine, which is Pro-Ject RPM 9.1 with class A cartridge and Tube Box phono, I know its very good turntable & arm, but is it class A ?

And if I upgrade the tonearm to a better one like 9cc Evo or other models will improve SQ very much and no need spend on higher level turntable ?

Or if I upgrade to higher level turntable like Signature 10, or other brands like VPI Classic 3 . How much improvement will be ?

My main goal is: resolution, musical, neutrality, and no coloration.

I'm trying to understand what best way and is it worth to spend more money.

Thank you

You should be specific about your cartridge if you want on point answers to your question.

Without knowing your cartridge, I would say the weakest link in your analog system is the Tube box.
It doesnt really get better at this point ...it will just be different. If you like what your hearing now...I would just improve on Isolating the turntable with some better feet or a wooden platform base . (like mapleshade sells) You can spend lots of $$ and still be a little dissappointed.
I would agree with Jperry, your Shelter 9000 should benefit from a better phono pre bringing it to a whole new level of resolution and musicality.
