Thank you all, for helping me.

ِDear tablejockey i didn't get disturbed, actually i like persons who are straightforward.
If you want full story, no dealer recommended me that cart, i received rega planar 3 as a gift one month ago and even didn't open yet ,
searched on net and find it doesn't have VTA, now i am in dilemma to keep it or sell it and replace with another turntable.
I give dynavector XX-2 as an example because my friend have it and said he will give me the cart for testing.
My phonostage is accuphase AD-50 preinstalled on accuphase E460 amplifier.

If you want to try a MC cart,I would consider the Rega Ania cart. What better, than the cart designed to go with the table.

No need for alignment fuss or VTA concerns. Price also, is more inline with the P3.
