Hey OP, @ucdmac122005,
As yourself, does this sound like the opinion of someone you can trust to be unbiased, take some care in their listening tests? Pretty much a given whoever wrote this does not have a firm grasp of the physics of electricity, how electronics work, etc. They have to make a call to some hereto unknown facet of theoretical physics, of which they have no evidence or proof. Take that for what it is.
As the 'Flat Earth Church of Pushing Electrons Through Metals' continues
it's fevered program, to deliver the music lover from the demonic
influences of their own mental faculties and senses
(HOLLOW-HEADED-LUJAH, AMEN): the intrepid listen on and enjoy the
rewards of their own experimentation.
