I might do that, just to say I did. My ER is sitting in its original box, having demonstrated nothing of sonic significance to me. I am more of the viewpoint articulated by @Anupc and @Andrew in this thread. I believe cables, electrical noise, and many things can affect audio, and that in particular, there are many interactions in network audio we’re still figuring out. FMC converters and the GigaFoil 4 (which I use) can help reduce noise, but clocking a switch will neither affect the timing of the Upsampler/DAC, nor the noise on the line (though the ER can help with that, too). It’s asynchronous data. ER might help with other things, but not with timing issues that affect SQ.
