have the LPS, had the XGP.
the LPS has a fat bottom end, nice mids and decent highs. the XGP has detailed highs, very nice mids and a lean bottom end. I found the XGP to be arm dependant as well. it did not have much bottom end at all when mounted on a breuer 8C, but when moved to a reed 3P, the bottom end became very nice, not fat. it's really not a cart for rock. it's more for classic jazz and female vocals.
