(In case my dads old turntable sucks) What would be the best turntable to get to rip directly into 24bit FLAC?
You absolutely do not need to use that much space, as the loss less CD 16/44 is quite sufficient to archive LPs. CDs exceed the dynamic range of any LP except a dbx encoded one. The bass of CD is lower and the only area exceeded by LP is HF, but the CD goes out to 20 kHz. Unless you want to spend an awful lot of money, an LP cartridge will roll off before 20 kHz. The ones that can exceed 20 kHz, run into mechanical resonance issues above 20 kHz and it a good job we can't hear it.
It is nonsense that LP is superior to CD. The only reason this comes about, is that the long haired louts that master most pop and rock CDs don't know how, or are ordered to do it wrong.
In the classical wold, where engineering has been almost universally superb, it is quite evident that CD is a superior format to LP.
What is your Dad's old turntable.
