My two turntables both had 741s in the RIAA equaliser, which I replaced
with TL071s, only because I couldn't stand the idea of 741s. The TL071
is a direct plug-in replacement and the equalisers have their ICs on
sockets, so the replacement was easy. I didn't even have to solder
anything. I suppose the distortion of the TL071-equipped equaliser could
be lower than before (I didn't measure a before and after) but any
reduction would be swamped by the inherent distortion of vinyl and the
cartridge. I certainly haven't noticed any improvement, I just feel
better not having 741s in the signal path.

Were the 741's used for high-level equalisation or as the input-devices?
My phono stage has an LM301, but only as a buffer after the long-tailed
pair and current mirror, and still sounds good. I don't see any reason
to replace it.
