Even though the stated purpose of Gruve-Glide is to reduce static, I've always thought that it acted as a lubricant on the grooves. I get better imaging, and a more 'liquid' sound.
I use it sparingly on an LP-12 with a Clearaudio Virtuoso Wood MkII cartridge. When I bring an LP over to one friends house, who has a VPI TNT with a Van den Hul cartridge/needle, he gets a collection of 'stuff' on his needle (residue?) It seems the more the needle conforms to the shape of the groove, the less Gruve-Glide you need.
