I'm still here Raul, enjoying the banter.
Not that I should question your cleverness, but the only way I have ever been comfortable with an audio assessment is to do rapid AB comparisons. I have a new method which you will hate but @intactaudio will appreciate. If I want to compare two cartridges everything else in the chain has to be identical. I record both cartridges to my hard drive in 24/192 playing the same record. I can run both files at the same time and switch back and forth with the remote. You can compare any analog source this way.
Intactaudio, I recommend that people who have very small or no record collection at all should not get started in vinyl. It is problematic from a number of perspectives and silly expensive. It is for hobbyists like Lew, Raul and myself, people who already have insanely large vinyl collections who have to play them with something. We are like little old ladies around a little glass table at teatime discussing our medical issues.
