Is VTA and SRA the same thing?

@gregm So the VTA cannot be adjusted by the end user?

@wlutke Please explain more detail.
Thanks

Thank you all for the answers, but so far no one have answered directly my question: If I adjusted the VTA by 1 degree, will the SRA change with the same 1 degree?
Thanks

Thank you for all the responses gents. I understand a lot more.
Second question: Can we trust on the cartridge manufacture on the 92 degree SRA? I mean, if we can set the top of the cartridge perfectly parallel to the platter, then we can get very close to 92 degree?

@rauliruegas 
I understood what you said, that is why I said “very closed to 92 degree”

What I meant was since the lps have different thickness and some other variables, using microscope to find the 92 degree is only bring you to the boundary of 92 degree, therefore if we can trust the cartridge manufacturers we can save money on purchasing the microscope.

Correction: "parallel to the LP surface"
