This was something that really concerned me in Jurassic times. There's no problem with Shure, ADC, Ortofon, Goldring and Grado, at least I couldn't measure any difference in distortion, tracking etc. on Test Records.
So you actually looked at that?
Wow, there's someone just as geeky as I am.
This was early 80's. I'm really a speaker/mike man. I was hired by Calrec to do mikes, but I did far more electronics there cos that was where the money was.
My efforts with cartridges were far less successful. The brands I mention were those I could easilly (?) take apart & put back again. But I worked with Tony Emerson & Don Barlow who designed MC cartridges for LEAK in pre-Jurassic times.
I think the original TAA article called for a 100 uF beaded Tantalum (rhymes with unobtanium) after the first stage LMAO.
Jung was a pseudo prophet. He may have made exotic measurements of caps but he obviously never listened to them. Tants are evil. I've stripped every single Tant out of a REVOX A77 and replaced them with low leakage Al. electrolytics. Bateman is good on capacitors though I can't claim to have tried everything he did.
One of my specialties is integrating linear & non-linear electronics, DSP & speakers so the whole is greater than the sum of the parts. I call this Powered Integrated Super Sub technology but the Marketing Dept. never liked that.
The other is using Double Blind Listening Tests bla bla to design stuff. They like this even less cos it showed who was deaf.
On supa OPAs for audio, it would be nice to have a FET i/p OPA with low offset & the performance of NE5534 but only AD745/3 springs to mind. I HATE ib cancelling OPAs. They invariably have poorer real life noise compared to OPAs that don't - cos correlated noise. If I can't get rid of the evil o/p electrolytic, I'm not interested in paying extra and the additional aggro sourcing.
And it would be nice to swing rail-2-rail in a battery app.
Many of the supa OPAs have nasty latching behaviour which they don't tell you about in the specs.
