VPI Classic 4, any one have it?

i have received my VPI Classic 4 but with 12.7 tonearm, so my comparing is with my previous classic 1, definitely there is a big jump on it. music is more involving, there is laying of instruments, bass is more body and musical, more depth, wider soundstage,better in everything, very details. instead of getting the 3D printed arm, i thought i could use this money for another arm like the tri planar or graham.
Do anyone know VTA adjustment, 1/10 of 1"( that is one mark equal how many lift by degree. or 1" movement equal how many degree changes. i am new to this VTA. According to Roy Gregory + - 2mark a lot of changes but i cannot hear the different.
i am very happy to have this upgrade. it comes with piano black finish, surface is very rough cannot be clean i don't know what materials to use for cleaning the top, maybe vacuum it.
Thanks.

Bifwynne....no idea why it would sound better, only that it does.

Csng1....before I would get any other arm, I would listen to the 3D VPI and make a sound choice.

Csng1, the TriPlanar is an awesome arm, but be advised that it cannot be used with the periphery ring.

There's a VPI Classic 4 out now?!?!

Tough to keep abreast of these frequent(and costly) "improvments" constantly being issued by this company.

It will be probably take another year for me to add another arm, there is a 12" tri planar arm, is very costly around $10,000.00
I am done upgrading, need to fine tune VTA.
Probably get a esoteric k-3 player to replace my Sony xa9000es.
