DAC Regenerator and Reclocking Devices

A good article, at least the first few pages minus the sniping from the ever-present peanut gallery.

Re: USB vs spdif (AES/EBU, coax, optical), it depends where the DAC manufacturer chose to focus investment. Some (many?) of the latest DAC builders/sellers seem to be placing their main emphasis on superior USB circuitry. Some have effective galvanic isolation built in. Some even use FPGA technology to eliminate the traditional role of clocks in the DAC (Exogal Comet for example) and thus sensitivity to noise riding on the signal.

IMO, adding a USB to SPDIF converter to run AES/EBU between it and the DAC is not much different than adding the USB gizmos. Counter to Forest Gump’s wisdom ("One less thing."). That is unless your DAC cannot handle USB from your USB-only Linux-based server/renderer/streamer in which case it is likely to be "the lessor of the evils" solution and thus a smart one. The more flexible and expensive SRSs offer multiple output options if one can afford them. :)

@dlcockrum 

I stand corrected. My apologies.

"adding a USB to SPDIF converter to run AES/EBU between it and the DAC is not much different than adding the USB gizmos"

Dave, one exception in your scenario; the Aurender USB Audio 2.0 to SPDIF ( COAX ) Converter does not require external PSU compare to ISO Regen. That's one less gizmo in big scheme of things :-)

I have no experience with ISO Regen or Aurender USB Converter but since you own N100H, only you can determine which one of these gizmo sounds the best in your setup.  

Well said Lalit. Thanks.

+1, Dave.

A lot depends on whether your dac is designed primarily for usb or ethernet.
