...YOU NEED EXCELLENT CLOCKS...
So true. In digital audio the 1's and 0's are only half the story. Timing is the other half. The quality of the clock and the clock cables are critical.
With the ER I had it clocked to an Esoteric master clock generator, connected with a Shunyata Sigma clock cable. The clock cable alone was more than twice the price of the ER box itself. The ER box got very hot. Yet that ER supplied with impeccable Esoteric/Shunyata timing was no competition against the entry level POE powered Pakedge switch. The 1's and the 0's were the same, the Pakedge did not have the advantage of Esoteric timing, yet it sounded better. So there is something else at play here, more than the 1's and 0's and the timing.
