When people are in the studio, they produce records trying to make a certain sound - not what is played in the studio, but mixed to achieve a certain sound.
Right, but Doug Sax is famous for DIRECT CUT (Direct-To-Disk) recording techniques. This is when a signal from the mics going to the mixing console and to the cutter stylus (no reel to reel in between). Audiophiles raving about his Sheffield LAB direct cut albums. His monitoring cartridge was Stanton 881s (not even the best Stanton model, but close to the best models). In that TAS article many engineers claimed than MC has a lot of coloration and not true to the sound. This is an opinion, but an opinion from a very well educated sound engineers and mastering engineers with very good ears. @sokogear
It must be a very good MC to be neutral.
You should really try some killer MM cartridges, your Acutex can't speak for all MM or MI.
