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!!!

Jonathan, I was able to get to Audioquest thru the Lyra site via the Distributor link and have already heard back from them. I sure didn't see any of that going thru the Audioquest front door, but I could have missed a link.

I'm sure everybody says this, but I was extremely cautious with VTF settings and handling in general. It's a dainty little thing and just looking at it lets you know it's not going to take any punishment.

When I first read of a "low rider" Delos here I thought to myself, "Man, I'm glad mine has the correct ride height!" But it just kept creeping ever lower.

I have contacted Audioquest who responded quickly and professionally. Alasdair was helpful and my Kleos has been sent to Japan for warranty repair. Thanks to you and Audioquest for following up. My cartridge should be returning shortly.

I just started having this same issue with my Delos yesterday. bursts of what sounds like mistracking, randomly through an album side, very intermittent and lasting a couple of seconds, then fine, then on again. I checked all my connections and they are fine. Played the record on another table and it was fine. I am using a Sota Cosmos IV with SME 309 arm. VTF is at 1.8g.
Love the cartridge, but these bursts of noise are annoying, almost like a tweeter breaking up. Doesnt happen with CD or my other table though.

Manitunc....sorry to hear about your alarming experience.
One possibility is that given your max VTF, if the VTA is "tail down" the Washi paper could be skimming the warps on the disc(?)
Carts with an "undercarriage" tend to register disc contacts as loud thuds but the Lyra, whose stylus is mounted through the front panel, might instead just hash the high frequencies and sound mis-tracked whenever it touches down? Once friction gets going you might find an accumulation there too?
Just out of curiosity are you loading the cart "fully open" or with a fairly low resistance?

running with low resistance. I have reduced VTF to 1.7g and recleaned the stylus but havent had the chance to listen for a while.
