Dear OP
I am not surprised that you find double SC work
The most notable change from double SCs to Triple SCs is fuller and deeper bass with authority.
Also somehow it has more relaxed and clean decay.
With triple IC(Audio Note, Crystal Cable, Teo GCII), triple SC(double Audio Note and Teresonic Clarrison) and Synergistic Blue power cables, I am really happy with the sound from Lansche 4.1 speakers using either Silbatone 300B SET or Line Magnetic 508 SET.
It is musical, dynamic with nuanced details, wide and deep soundstage.
I had just stopped cable rolling at this point and will enjoy the music.
I am not the person who keep changing equipment very often.
But my humble 100K$ system sound much more musical than any systems that I had heard in many Audio Shows
