Did i miss somehing ?? There is no way you can transfer a flat file playing it through an RIAA preamp. It will contain low freq boost hi freq cut. My Op-amp Lab pre-amps are actually flat 20 hz to 20k hz. My Stanton is loaded with 47K and 240 uuf at the pre amp input. dnelson --- On Tue, 3/9/10, Corey Bailey <[log in to unmask]> wrote: > My plan is to transfer through an RIAA preamp, flat using > outboard analog EQ > and > flat using post EQ via software then comparing the files.
