The RIAA curve that is standard in modern phono preamps is not the only curve that was used in phono recordings. There are a number of old LPs and 78 that were recorded using various equalization curves.
Having a digital phono preamp that would allow customization of the selected equalization curve or the selection of some of the older standard equalization curves would be a great tool for those with 78s, LPs and other older vinyl recordings. As far as I know, nothing like this is currently available. I could be wrong, though.
I've included the following link as an FYI, in case you're curious about phono preamps for older recordings.
Really nice preamp from a really nice company.
