Just a note to clarify what the results show: 1. Yes, transports do make a difference. Small changes can be found between the Squeezebox units and laptops mainly in the extreme high frequencies... I suspect this is the result of timing differences with the -synchronous- SPDIF interface and my old adaptive isochronous USB DAC. This effect goes away with asynchronous USB DACs (ASUS Essence One, TEAC UD-501). 2. Digital cables -by themselves- do not seem to make any difference - TosLink, coaxial, USB, HDMI all measure the same for me (obviously so long as the digital data isn't being corrupted). Theoretically, extremely long cables could cause timing errors but I haven't seen this with a 12-foot length of plastic TosLink (2x6' connected with plastic optocoupler) or 25-foot poor quality coaxial SPDIF. Of course, my billionaire playboy friend Keaton Goulden-Eyre III subjectively heard differences ;-). I'm still looking for the opportunity to borrow some expensive cables to try from the local audio store but have not been down there in a few months now...
