Boa2, this discussion started out, for me, to see if I could keep the original poster from being taken in by you snake-oil salespeople. After that I was simply surprised by the fervor of the counterattack, and the discussion became fun. I'm being told to shut up, go away, and I'm being rather humorously insulted.
By the way, you are confusing my contention that *power cables* and outlets can't affect the sound (as compared to properly functioning and spec'd alternatives) with a blanket statement that all cables can't affect the sound of a system. Interconnects and speaker cables can provably affect a system's sound, though usually if they are incorrectly engineered. If you use 22AWG or smaller speaker cables, interconnects with overly high capacitance, or numerous other situations I can think of off the top of my head, there will likely be audible artifacts. This is because THESE CABLES ARE IN THE AUDIO SIGNAL PATH. See how that works?
On the other hand you would be correct if you assume I don't think there are audible differences between two cables - of any sort - with the same specifications.
