I must confess I used to set my SC to a level of 3 when I first got it in spring of 2020. Every time there was a firmware upgrade it seemed to reset itself to a level of 5. I'd go in and reset it to back to 3. There were so many firmware upgrades during the remainder of 2020, I got sick of resetting it. I decided to leave it at 5 and pulled out my best sounding LPs to see if I heard the SC in action at 5 vs. 3. The answer was "no". I decided if I don't hear it, life was too short and there was no meed to remember changing from 5 back to 3. I don't think I've mentioned this on here before, but I do start hearing the SC when the level gets higher than 5. Sometimes at 6, but usually around 7 or so. I was a bit surprised that when I did the upgrade to all of my Parasound equipment in late December 2022, I still can't hear the SC. This surprised me, quite honestly, because this new gear is so quiet and extracts so much additional detail from the music. I upgraded to a JC3+ phono pre-amp, fed to a JC2 BP pre-amp, feeding a JC5 amp but I still can't hear a thing. One of the things about the level of added detail this equipment reveals is it does so at low volumes too. Up until 12W rms it operates in class A mode which means very low distortion. All of this means you don't have to listen louder to hear more. I used to turn the volume down at night and if I liked the LP enough, I would revisit it during the next day and crank it up to "hear what I missed". I find the new gear sounds so great I am listening about 5 db louder than I used to during the day. High or low volume, the details are still there. All of this is a long way of saying: If the SC was doing anything, I'm sure I'd hear it on this gear. Now more than ever. I hear so much fine detail in the high frequencies. Hard cymbal crashes fade out into blackness without wavering or suddenly disappearing at a certain volume level. Also if the drummer is softly tapping the ride cymbal as a song fades out, I hear it fade into black. Now I will say almost all of the music I listen to is not any sort of EDM or electronic music of any kind. This is said to be the type of music the SC can really struggle with. Hee hee, I struggle with it too which is why I don't listen to it. On my system, in my room with my ears and listening to the type of music I like....The SC doesn't alter the character of the sound one bit. YMMV.
