Hello Phil, I share your believe that there must be measurable differences or one should call it snake oil. Music and audio is about passion and that is why discussion quickly become passionate. About components: I always had silver audio cables in my system, but I use it for a good laugh to casual listeners on how precious the system is ;-) I have a hard time understanding why one should paint the CD edge with a pen or fluid, put a mat on top of it, use vibration free stands for amplifiers (anyone tried this on the SqueezeBox?), use special wall outlets, use podiums to avoid speaker cables from touching the floor, ferrite cores or expensive power cables. I had an epiphany though. I bought a PS Audio 300 power source for CD/preamp when I moved from the 120V part of the world to 240V. It is used as a nice, overpriced transformer. I was shocked by the audible sonic change it brought with it, because I did not expect anything. I will try it with the SqueezeBox 3 and will post something in case of a change. I also can understand why a PCM switching power supply introduces voltage variations and can imagine a difference to a linear power supply. About break-in: the Squeezebox sounds different to my ears after 20 hours, which I account to my getting used to it. Break-in always is reported as improving the sound. I see no reason, why this should only go one-way. In general, there is a measurable shift of the electrical characteristics of components and ICs within the first 100h (have enough leakage, C(V) data to prove it). Major reason is that charges get incorporated in dielectrics, but this saturates quite quickly. After several years there is then gradual fatigue, which leads to leakages and break-down and the component dies. However, for ICs at least the functionality and output signals in general do not change, because the circuit is designed to compensate internally for process variations and drifts over lifetime. BTW process / production variations by far exceed the break-in changes.
