Frequently Asked Questions
It works with any standard S/PDIF device, but optimal results are achieved when paired with other Expert Sleepers modules for seamless integration and synchronization.
96kHz offers slightly higher fidelity and more accurate transient reproduction, but the increased power draw is something to consider based on your PSU’s capacity.
While the S/PDIF functionality works standalone, the I2S connection unlocks advanced features like sample rate conversion and synchronization between ESX modules, maximizing the module's capabilities.
