A minor point, but Fremer says that conventional phono preamps are disqualified from this digital RIAA curve thing because they all do RIAA.

But the popular Bellari VP530 actually has a button that toggles RIAA EQ (i.e. you can turn it off and feed the non-EQ'd signal to your computer via USB or the RCA outs). Minor point, but could be useful if you're wanting to go that route.
