Ever since Jason Stoddard suggested that the EITR 'might' be pulled from the product line a few weeks ago, I have wanted to buy another one. Neither Schiit UK or Dutch distributors have had them for weeks. I thought it might be a problem with short supply of the EU power supply, so I continue to wait.
This is a wonderful USB-S/PDIF device and would be a pity if it were no longer available ... but I understand the potential business reason.
I have recently taken to injecting 5v directly to the USB-B plug from an Uptone UltraCap LPS-1 (suggested by a member on another forum), thereby isolating the bus power from the Mac .... and the results in both my systems are quite revealing. I'm not sure why there should be a resulting SQ difference, given the levels of isolation that exist in the design.
