The X-lp uses a fairly basic circuit and uses bog-standard industrial components and 5532 op-amp.You could start by changing the op-amps, a search of the archives will produce a variety of opinions on what would sound good. Audio grade electrolytics would help. The power supply is unusual, it uses a voltage quadrupling circuit to derive 25-0-25 rails from a single 12v transformer winding. 7815 and 7915 regulators are used. There aren't really any much better regulators that are a straight swap for these, 317/337 regs would need extra components to work and space is tight. Small axial rectifiers are used maybe swapping these for schottky's would help. I don't own an X-lp I did look at a friends with a view to modding it so this is all from memory.
ope this gives you a few ideas to get you going
