Raul - you give me a lecture on how to test properly, but you can't even install a cartridge properly in your own system.
Like you I own an original Dynavector Karat Nova 13D.
Here is a video showing you the error in your set up. You installed this cartridge such that the headshell is mounted upside down in your tonearm.

Furthermore I think you are wrong to adjust the SPL and listening position when you change the TT set up - the rest of the system should remain constant for true comparisons.

Dear dover: I must add that that PURE MUSIC SIGNAL that pass through the internal tonearm wires when " touch " the IC cables that send it to the phonopreamp starts the continuos degradation of that true grooves modulations information all over each single link in the system audio chain.
Now, when any kind of distortions " disappear " in that first link ( cartridge/tonearm/TT ) then all the additional single system links distortions are more evident and we have to fine tune each of those system links and sometimes even change some of those links as cables or electronics even we have to adjust our seat position and the speakers position and a check up that the room treatment is not overdamped even to check the SPL we are listening in this totally new experience.
This check up of the SPL we are listening is important because when the distortions goes lower and lower we think that the volume/SPL of what we are hearing goes lower too but it's not really in that way. What's happening is that you are not hearing to the high distortions you were accustom to.
