"Why not just record with no EQ and have a recording that is same as original? If source is Ortofon cart recording should be no brighter or different than otherwise, right?Or if the cart is too bright to start, maybe something can be done there"
I agree with mapman here. Digitizing of LPs is a very laborious process. It's not something I undertake often but when I do, I want the cleanest, most accurate dub of the LP that's possible. It's one thing to apply some EQ to the occasionally bad LP but if you find that is frequently needed, it suggests something else might be awry. It's better to fix the problem at the source, imo.
