PS or XP

[xrayspex]

Having built a Truepath and an AMP6 (don't ask why) I'm now contemplating an AMP15 build.
Are there any differences in soundquality between the XP or PS?
I do not need the extra power I'm more interested in fidelity.

I'm sure someone must have compared the two?

I don't recall having seen a one-to-one comparison. It's interesting to know though. So +1 on the question :)
