"The 12g Mil-Spec wire mentioned in this thread is unacceptable to me for full range applications since it rolls off the highs even when used singly."
Nothing about the physical properties of 12 ga wire indicates that this should occur at audio freqencies. What degree of attenuation have you measured?

We have been told that you need 12awg to couple a 12AX7 plate to the next stage. Major improvements were cited. Dennis also claims there are "hundreds of amperes in musical peaks" at this stage in the amp.We have been coached relentlessly on the need for double and triple runs of 19awg wire for signal path.
Now we hear this is all wrong. Too thick a wire kill the high end? What about all the claimed improvements over the years? You mean none of these people ever noticed that until now?
When is this BS going ot stop being condoned on this forum? Fortunately it's not tolerated over in DIY AUdio.
Did any of the followers consider the loss of highs may be the weak 12AX7 or equivalent driving into the output grid capacitance?

"Did any of the followers consider the loss of highs may be the weak 12AX7..."
More likely the acoustic bias of the listener. My amps always sound better after a cup of coffee. :)

Just for the record : No one I know of, or myself, has ever used 12 AWG wire to connect a RCA jack's "hot" terminal, to the grid of a driver tube, ever. I think some posting have gotten it incorrectly. or are flustered.
Have fun, I do !!

Be ready for those strange answers.
Tk let's leave this for the subjective only NO measuring can measure what we hear so for cripes sake already
SUBJECTIVE ONLY!!!!!!
I'm fine with your subjective analysis, as long as you include the statement that it's "what I think I hear." Alternately, you could note this lack of frequency response is only an unverified opinion, and that your hearing hasn't been professionally tested to determine your ability to discern frequency aberrations with complex musical material. Without those qualifications (or something similar), your statement that 12 ga wire degrades high frequency response is simply nonsense. It has no place in a discussion of the physical properties of either wire or amplifiers, and it only serves to mislead other members.
