What are you talking about, Gavin?
Try saying what you just said to Peter Lederman of Soundsmith. You think he's any more mass market than VDH? He's pretty boutique, and QC is exemplary.
I've owned four vdH cartridges without experiencing a single quality control issue.
The only defects i have suffered are the result of my clumsiness, and a ZeroDust stylus cleaner pulling the diamond from the cantilever. So really, just more clumsiness.
By contrast i rejected two Kiseki Purplehearts for qc issues.
The design of Colibri has an exposed cantilever that is vulnerable to damage. I suspect this is responsible for some of the issues here.
In terms of setup, despite being a novice, with the assistance of kind forum members i have been able to achieve very satisfying results. So it may be tricky, but if someone as cack- handed as me can manage it, there's really no excuse for higher echelon audiophiles
Going back to the MS vs GC, my only criticism of my Ebony Grand Cru would be that it's a better all-rounder than my previous Koa Stradivarius, but so far it lacks some of the magic. The characterisation as 'smooth' i can agree with, i feel a slight lack of excitement, perhaps a less dynamic presentation.
The overall tonal balance is superior to any of my previous Colibri, i felt my Koa Strad had a magical quality in the treble but lacked body, weight, grunt in the bass, even though it gave up nothing in actual bass extension, it was just less forward than i was used to from the Ebony-bodied examples.
However i have two significant caveats. I've not had the 200 hour service, so there is probably more to come. And I still haven't mounted it on the arm it is destined for as that is under construction.
(Another pesky artisan, Frank Schroder.)
I suspect the most likely course of action will be to keep the GC and commission a Master Signature Stradivarius. It may be that the MS has a more dynamic presentation, i haven't owned one so i would like to see. But i do value dynamics very highly. The GC isnt lacking, but nor has it yet quite fulfilled the promise hinted at as i climbed the Colibri ranks.
I jumped from Koa Strad right to GC, missing the Master Signature iterations altogether.
Now i feel i should be certain I'm not missing what i might actually consider to be the most satisfying presentation for my tastes.
But will i sell my Gran Cru?
Doubtful
