Ortofon are a super company to deal with, their cartridges are excellent performers and, excepting the MC Anna, are realistically priced.
I've used an MC2000, MC3000, a loaned MC5000, the MC7500, 2 Rohmanns, an MC Windfeld and presently an MC A90. Not a single issue to date, all have operated flawlessly.
The only upper level cartridges I haven't had experience with are the Anna, Jubilee, Kontrapunkts and the Valencia and Vienna range.
Some may find them dark tonally, despite the fact that they're often written about in terms of neutrality the Ortofon has a much less prominent character or colouration than many other transducers. Careful matching can offset this.
They do not appear to be fussy either.
The midrange is the thing, searching for low register enhancement or a sweeter high frequency look elsewhere - the Ortofon is beautifully balanced, tracks wonderfully and never fatigues in presentation.
