Nagaoka MP-100 QA issues.

Edit: title should be mp-110.....

I bought this cart for the rave reviews and nice price point. For the money the sound signature is great, but when the honeymoon phase was over and I started to listen more critically I noticed some amount of IGD on almost every record. Most of the time it's barely noticeable and sometimes it's terrible(imo). Then I found a few records with some nasty sibilance. This blew my mind because literally everyone said this stylus doesn't suffer from either of those issues. For me I'd say for non-critical listening that's true 90% of the time and for critical listening it's more like 75% maybe less.

I've had the opportunity to swap every component, including the table, with no change. I've aligned and re-aligned enough to know it's good. And the only thing that worked was swapping to the much more expensive AT 540ML.

I've seen more chatter about this issue lately and I'm curious how many other people are having problems with thd 110's?

Here are a couple of pictures to show you what I've seen all of these are new or basically new styluses.

Notice the cart lean to the right. Not as bad with this one others have been worse:

Same cart with 0.5g VTF:

Proof it's aligned:

Cantilever not centered, again not the worst example but should be centred right?

Kimsrk: Well, what did you expect - wonders from a comparatively blunt (0.4 x 0.7 mil), bonded elliptical tip?

I haven't had any problems with mine. I run it at 1.9 grams. After a few hours of breaking time it sounds pretty good. I did switch from Stevensons alignment to Baerwald and like how it sounds better. I haven't noticed any IGD, even with headphones.
 
I had mp-110 aligned using a stevenson arc protractor on my p3 with rb330 tonearm, and that solved IGN/silibance.
 
I've got one on a Denon DP-400 at 1.8gms and it tracks all bands of my test record fine.
Sounds good too but it seemed to only be at its best after around 30 hrs.
 
Honestly, the whole Nagaoka thing is a bit overblown — they are nice cartridges but something like the (very inexpensive) AT-VM95ML would track better than any Nagaoka except MP500 (which costs 5 times as much).
