I ordered this along with the rest of the Synchro-mesh and Dynamo kit to go with my Sonos and PS Audio Direct Stream DAC.
In brief, I highly recommend it. The difference, even with the reclocking that my DAC is already doing, is subtle but noticable. The nice thing about the Sonos is that the Toslink and Coax outputs are both always on, so I can run them both, one straight to the DAC and one through the SM, and flip instantly between them using the DAC remote control. This makes evaluating the SQ real easy.
I could pick out the difference on day 1 but it was probably after 30 or 40 hours of playback that I was really able to pick out the difference. Now I'm hearing a spooky level of detail in songs that I'm familiar with, particularly in echos, cymbals, sustains, decay, layered effects, things like this.
With the audition terms it's a no brainer, and you already know that Steve is a prince to deal with. So, I suggest you go for it.
