Hello again. Sorry that I was away with my other new toy...
I was a beta tester for a cable maker and tested about 10 versions of his ICs. This guy is quite interesting. He told me that he would never share any findings from his IC experiments with others. This is similar to a good friend of mine from Kansas. He makes the best BBQ that I have ever had. He told me that his grandpa would not pass the recipe to his own family until he was *very* ill...
My point is that EE courses only teach the basics. A lot of know-hows, tuning, refinement, and/or tweaking are the accumulation of experiences in the said field. Most companies' whitepapers most likely will not reveal their secret ingredients.
Bill, have you had the chance to find out the capacitance of your AH ICs? Note that Bill's configuration needs 5ft of ICs and mine needs 10ft. Bill's power amp is more sensitive and so his Dude preamp needs to have higher attenuations and thus lower output impedance. (Review Al's note about 75/25 vs. 50/50, using Thevenin's Theorem.) Consequently, the requirement for his setup is not as strict as mine.
Thanks all for the contribution.
