It's Simple


Cables have properties Inductance L, Resistance R and Capacitance C.
Ditto loudspeaker, connectors, electronics in and out. 

LRC are used to create filters aka Tone Controls.
Filters cause amplitude and phase changes.

Cascading LRC creates a very complex filter.

Another's opinion on a particular cable may not be valid unless they have a very similar system.

I kind of hate to bring this up, but there are obviously many variables besides L R and C involved with how cables sound, some of which I’ve alredy mentioned. There are also the variables of floor borne vibration and static electric charge, which is why cables should usually be suspended off the floor and why some sort of anti-static spray or device should be employed. A demagnetizer should be employed, making magnetism another variable. There are other variables, too, perhaps beyond scope. All of this, plus what others have posted, such as metal purity, etc, suggests that L R and C are not really the only game in town, as much as we might aspire to embrace mathematics and “classical electronics” as the end-all do-all for our hobby. It’s not nice to fool Mother Nature.
Kijanki, the calculation of a 6 db difference you provided in your post yesterday was correct, but it was for the wrong thing :-)

Note that in Ian's calculation there is also a 6 db difference between the 4 ohm situation and the 8 ohm situation -- the voltage drop **in the cable** of 10 millivolts vs. 5 millivolts!

Al, I should've known better.  I calculate dividers almost every day, but yesterday was my "slow" day.  On positive note, I didn't make any bank transactions  :)

It's a pleasure to read an Audiogon thread where Geoff is totally ignored, in spite of his attempts at garnering attention. 

Audiogon ought to modify their policy where moderation is concerned. Just my opinion, of course.

As the thread suggests, "it's simple" really.
To the ops original thought . You mean this can all be scientifically explained ! Crap , I liked the mystery and unknown aspects of wires and cables . Thanks for shattering the illusion .
