ART 9(old version) former user. VPI table
Presently using a cart 2X the MSRP of the 9. Definitely NOT twice the performance. Naturally, it's subjective and system build.
Have you maxed out your phonostage budget? If not, you're not hearing the ART9 at it's "best." Based on your profile, you will hear the ART9 as a new cart with a phonostage upgrade.
After that, prepare for the new table.
