I removed all the ERS Paper from my system and put everything nude on the floor, it sounded amazing. Very open and smooth. I could listen for hours!
Then I wrapped the Valhalla power cord for DAC1 and I got more blackness, I was hearing a completely different flavor of sound. But synergy sounded messed up because I was hearing a mixture of flavors. The whole system needs to have the same tweaks to get synergy, I have heard it with cables, isolation feet, shielding, MultiWaves of Power Plant, connectors. All components need to have the same tweaks in the system, then it sounds amazing.
Everything nude on the floor sounds amazing, everything wrapped with ERS Paper also sounds amazing.
