Not to put too fine a point on this matter, but you profess to have no understanding as to why there may be an audible difference between amplifiers and therefore mock those who report audible differences between amplifiers.

Same for cabling, perhaps CD players as well if I recall your previous posts correctly.

All I'm suggesting is you might want to adopt a more modest and less strident certainty in your expression of your own opinions.

Enjoy the Music. Trust your ears. Laugh at Folks Who Claim to Know it All.
