Last March I upgraded from a Grado Platinum to a Lyra Delos cartridge which was installed by Analogique in Manhattan.My turntable is a VPI HW-19 MK-3 with an Audioquest PT-6 tonearm.After about 120 hours of use I have been getting distortion on certain lps.For example:Last night I wanted to hear Moment's Notice from Coltrane's Blue Train lp(180 gram).This is the second track on side one.So I drop the needle on track two and sound starts distorting at about the 7 minute mark(track is 9:09 minutes),I lift up the needle then lower it onto the lp again and it plays fine.This is not happening on every lp but it is happening quite often.I am tracking at 1.8 which is the Lyra recommendation.I switched phonostages but that does not seem to be the problem.I also put on a new belt but problem persists. Help!!!
