Waldhorner, I hesitate to make this seem even more wacky to you, but if you take a "burnt-in" cable out of a system and coil it up for a period and then put it back in the system it will go through the burn-in process again, albeit more mildly. I presume this has something to do with physical compression/decompression of the dialectric - whatever. You may doubt this effect, but you should take it into account when doing your tests between new and burnt-in cables. Personally I have not found a huge difference between new and burnt-in versions of cables like say DHLabs, but the differences seem to be more noticeable with more expensive cables. Perhaps the difference is quite subtle and only stands out against an otherwise pristine performance. The differences can sometimes be very unsubtle in the bass, but the nauture of the change is not usually a gross frequency response issue, but a change in grain structure or a change from seeming mechanical/electronic, to becoming more natural musically. The process is so repeated and unwelcome with any new product that it is hard to ascribe it to anything other than a "real" source. I know the following experience does not meet your objective test criteria, but in repeated visits to a friend's house I have heard how his system has burnt in. You may scoff at the aural memory required to support this claim - but I can recall how much more I was able to enjoy the music at each visit. How come my burn-in, if that was what it was, had the same gestation period as my friend's when he had an order of magnitude (or two) more exposure to his system? It is not this one experience that convinces me, but the many times I have observed the burn-in process.
