I concur with your sentiments regarding 'overthinking' things. Vinyl fans know that cartridges vary in performance and part of the fun is experimenting. I've got the 2M Red too, which retails for about 100. By all counts its a good entry level cartridge, but this is a technology in which more money really can get you more SQ. I'd love to try moving coil designs as they have superior high end reproduction, but cost much more. It never ends!
I used Ortofon Moving Coils for decades with my Revox B795 TT which I have since given to my daughter.
That being said, I am very pleased with the fidelity of the Ortofon Red supplied with my Pro-Ject Carbon Turntable.
When (or if) the Red Stylus ever wears out I will replace it with the Blue just for fun.
But not sure if it will wear out as that would be at about 500 hours and I don't have that many hours of vinyl left to digitize which is what I've been using my turntables to digitize.
So, from me, who's owned turntables since 1974 and have had experience with top of the line Stantons, Shure's as well as Ortofon Moving Coils, the Ortofon gets a score of 9 out of ten.
Love the Pro-Ject Carbon but it's actually my very first fully manual Turntable.
I loved my Sony PSX75 Turntable which I traded with my Dad for his Revox B795 because the Sony tracked warped records better.
I wish I had grabbed that Sony PSX75 back after he died, to be honest.
Nevertheless the manual Pro-Ject with the Ortofon Red is a fine combination and certainly nothing you should be ashamed of or feel needs an immediate upgrade.
