I agree with the others.
100 ohms loading and about 2.0 grams of VTF.
(Sorry, I can't help you with the Phantom though, I use a Basis Vector M3 myself.)
As far as the sound, it is the best cartridge I've owned, and easily bested the Shelter 90X as well as the Koetsu Rosewood Signature. It has a wonderfully refined and extended treble response when it is dialed in correctly, so your experience of thin and bright does not coincide with my experience at all.
Good Luck and hang in there, as the XV-1S is a wonderful cartridge.
