Another XP-15 owner here -- I've had mine for ~3 years now, and it's definitely a keeper.
On a side note, I have read the XP-17 replacement is a bit quieter still, but also a shade cooler. Take that for what you will.
I would not trade my XP-15 for a JC3+, though I am sure it's also a very good phono preamp.
Do I still lust for a Herron Audio VTPH-2A? Absolutely.
Will I get one? Probably...
