To SAM or not to SAM and DRC

[Jean-Marie]

An other interesting point is not not every phase shift is audible. I find it fascinating that one cannot distinguish by ear whether the bow of a violin is being pushed or pulled, but if you look at the spectrum, the harmonics are seriously phase shifted between the two.

One thing that would be interesting would be to do the test with the SAM percentage to zero, which if I have understood correctly would turn down the bass extension aspect and only leave the phase correction of the phase.

Very interesting. I didn't knew that there is a phase shift in push/pull a bow on a violin. So the sound on one tone could go on for ever if there was a perfect musician playing one tone on a violin in perfection with zero pause between push/pull and you won't recognize a difference? Would be interesting to audition even if not perfect. I like those trials. Keeps my brain trained to be attentive.

We did the test also with SAM@0%. The result was the same. Loosing (all  ) micro details around the instruments/singer connecting them to the recording room as micro reverberation details.

So in theory that should put out of the equation the possible effect and phase shift of the bass extension.

Only remained the processing done for correcting the phase of the speaker.

I was reading the theory being the Manger transducer and it is quite different from traditional speakers, especially in the phase sector.... 

I'm reaching here my threshold of incompetency and will not be able to go deeper.
