Is there a problem with my Lyra Delos cartridge?


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!!!

That sounds lexactly like what happened to me some months ago when some crud had built up on my stylus (on a different cart), but I assume you have checked for that, cleaned the stylus, etc? By the way, how are you liking the Delos otherwise, in comparison to the Grado?
I always check the stylus for dust so that is not the problem.I clean my vinyl with the VPI 16.5 record cleaner.I am worried that the cartridge may be defective. The Delos sounds great,I just want to resolve this problem so I can enjoy my lp collection.I have been thinking about upgrading to the VPI Classic One. Thanks for your response.
I would contact Immedia or Jonathan Carr, who posts here once and a while. I had a Delos and traded uo to the Kleos and haven't had that issue. It sounds like a problem with the suspension or maybe the coils, but either way I would have it checked out.
