Do you use SAM?

on with 0% in the past, off since yesterday. After some system tuning on the digital frontend (Mutec Ref10) I noticed that I can get better resolution and transparency without it. Speakers are Giya G2.

Hi Vivialet, your perception is exactly right.
The more 'In Phase' your digital frontend signal (the signals bits&bites) gets the more you won't need (or do reject) SAM in your system.
SAM is a disimprovement for an audiophile listener who has tuned his system to the point where subtle changes in the (digital) chain can cause immense deterioration.

Transparency is a consequence when one can reduce jitter and improves 'In Phase Signal Integrity' in his audio chain. If you then add something like SAM that corrupts this integrity it's a must you loose transparency again.

SAM gives a 'virtual transparency' to an audio system as it 'cuts' off the tinyest of the signals due to phase shifts it produces (it swirls the phase of this tiny signals so your brain can't locate them together again. The swirled informations just add to background of your music then).

This 'virtual transparency' you can hear in form of better locatability of instruments and voices...more air (the void) all around the instruments...at least so it seems.
But that's an illusion...because better locatability in this case comes from cutting of the 'space' (tiny informations) around instruments and voices. It cuts off the tiny information of the recording room (only the big bulk of it stays and you have better perception of this)  and adds void to the scene hence the 'virtual transparency' you perceive. Your brain has less to work hence can better locate the origins of sounds.

If your system hasn't achieved a certain level of accuracy for the signal (signal phase integrity) yet you might gain more than you loose by using SAM.
But at a certain level of transparency you won't let go at this fascination of listening into the details and emotions of your music you never heard in such clarity.

I hope I could contribute to the fuzzy of space & time
