First...John...I'm heading your way for breakfast!!! Hold the avacado!!

Next...I'm somewhere on the fence here. And it's not a lack of faith in science...but rather the lack of any real science in that article. Hand waving and carte blanche statements about a $15000 amp sounding no better or marginally better than a $500 amp...really doesn't mean much to me. He offered no scientific data/references to back up this claim. He says double blind studies were conducted...etc etc. Where...by who...where are the references??? And...let's just suppose by some miracle ...this was true??... It would only be true the first day out of the box. Electronic components age...and often less than gracefully--higher end components...usually have much higher MBTF rates.

You don't have to convince me with regards to cables -- a few semesters of fields will remind you that at audio frequencies -- changes in impedance are negligible.
