"(However, RIAA encoding and decoding causes LOTS of phase distortion due to the multiple filters used on both ends)."Isn't the phase corrected, along with the amplitude, with the application of the RIAA filter* in the phono preamp?
Note* I think that filter is more correctly called a "reverse RIAA filter". The filter use when making the record is the RIAA filter.
To be clear, A "RIAA filter" (the one used to make a record) cuts the bass and boosts the highs. A "reverse RIAA filter" (the one used to play a record, ie; the one in our phono preamps) boosts the bass and cuts the highs.

Generally, no. There are innumerable designs for filters on both ends, each with their own phase signatures (for lack of a better term).
