Chris, The CD player is connected by analog output to the preamplifier. I use BJ cables (they seem to be passing the electrons just fine
) Placebo effect still possible.
As I said, if you're using the analog stage of the CD player, then a better model can improve the sound. I noticed quite an improvement from a 1st gen Sony DVD player to 2007 flagship Pioneer Elite model. But any player which can completely get the bits off the disc and hand them to the receiver in digital form will sound the same as any other model performing the same task.
If bi-amping or bi-wiring M80s makes no difference, then I suspect the dual sets of binding posts are included for those who believe there is a difference.
It is pretty much a required feature of any high-end speaker. If Axiom didn't include them it would be a "con" on every review. Hopefully it adds very little to the price.
