+1 reubent. FWIW, I'd start with the 2M Blue stylus and complete re-alignment. Those things often have a bigger effect than cables. I'm not a big fan of XLR adapters; just another mechanical interface set to introduce noise. Caig DeOxit should be all you might conceivably need given the age of your gear.
Cartridge compatibility is not a concern; your Ayre will handle pretty much anything. Just make sure your phono section gain is set to 40 dB and resistance is 50 kOhms for your 2M Red or any other MM cart.
That said, some speakers like some cartridges better than others. That's something that is largely subjective and has been addressed in many other threads. Again, I wouldn't worry about it; you;re just trying to get a handle on whether the vinyl thing is good for YOU.
Note that the LP itself can have a dramatic effect. Some are just plain bad, and some will rock your world. Most are in the middle somewhere. Use a decent cleaning process (once more, lots of threads here on that) and pick some music you like.
FWIW, I feel that vinyl is superior to digital in every way. I have a superior DAC, disc player and vinyl rig and after doing hours of A-B testing, I'm always happier with the vinyl. It just sounds more natural to my ears.
That's why this is such a fun hobby: Finding that happy listening!
