I may end up using my XT for at least some stuff pretty soon again and I'm trying to maximize my potential here. Are you using a DI or 1/4 to XLR cable to the input? If you are using a DI, what brand and is it active or passive?
My findings - avoid active DIs. Even the expensive ones. They add something to the tone that is really nasty. A pro recommended a cheap passive DI - I bought a ProCo and life it good. I tried five or six actives, ranging from the Behringer to the BSS Audios we use - the cheap ProCo was by far the best tonally - and quieter.
Now I also run a Harmonic Converger with great results, but I won't say it's a must-have. The designer is a friend of mine (though he charged me full price, which I was glad to pay). I find it adds a nice tubular character and clears up some higher-end junk. But they ain't cheap...
HC runs between the DI and POD. I run one at home and record with it as well.
Some POD users don't even bother with a DI. The POD signal can go direct. The DI just lets you do it with XLR cables instead of 1/4".
I tried my POD ( one of the first) through my PA, just 1/4" cords - and I was surprised that it didn't sound good at all - wasn't trying to anything fancy, just get a decent jazz tone for my ES-175 through a Mackie board; I could not get any decent tone from it. How do you set up the tone characteristics differently from 'phones' sound?
I really like the idea of the POD, but...
