Maybe, for fun, ones that allow use of other equalization curves. I don't care if RIAA was completely adopted a long while ago, I've heard use of other equalization curves, and there are some records that happen to sound better in a specific setup with a different curve. Zanden makes a nice tube unit with built in SUT that sounds pretty good. For solid state, the FM Acoustic phono stage is really interesting because it allows an infinite variety of equalizations. One uses two controls, one selects the turnover frequency, the other selects the slope of the curve. I only briefly heard this thing at a show, but, it looks like it could be fun to try some unique equalization curves.
