"The notion that RF rules do not apply
is what lead us down this road."

Well, physics (nature) IS largely indifferent to our intentions...

I've finished reading your materials and the part I liked the best was the correlation of our ability to hear mid-range phase shifts with our speech recognition capability. That makes a lot of sense now that it's been pointed out to me!

As far as the RF performance of cables, it depends... I see it as a secondary effect that only affects AF if it causes intermod at either end. Whether it's due to signal pick-up or reflections, the root cause of audible problems is always a design flaw in the active I/O stages that allows energy to enter that they don't have the GBW to handle. As all those loop-d-loops on your Smith Chart show the real world is ugly if you don't have a conjugate match at the load and if there is anything certain in home audio it's that you won't, not even in-band!

I use magnet wire, open-line interconnects (~300ohms) between most of my gear (cheap way to get low dielectric absorption) and normally they sound best with a resistive termination at the load and a build-out at the source. At the power-amp/speaker end of things I've found that frequently hanging a real resistor at the speaker terminals smooths out the highs. I think many speakers largely unload after the tweeters go inductive and there's nothing like a little real loss to calm down a system...

The watery filters in the back are very odd indeed. Do you have any measurements of their impedance vs F over a few configurations?

Thanks for the interesting read...

Rick
