Re: Fact or opinion
"statement that Sony and Sennheiser both boast of superior audio quality
Of course, much depends on whether you listening to Vinyl or CD, or (God help us), MP3.
And whether you use mono-directional, oxygen free Monster cables."
Not this nonsense again.
A well ripped MP3 from a good quality CD will be indistinguishable from the original to almost anyone, and leaps and bounds ahead in sound quality of a vinyl disk taken from the same master.
MP3 in its early days was indeed crap. It has had many years and is now actually excellent.
Don't believe me, grab a copy of Foobar and the ABX plugin. Then take a properly ripped MP3 (use EAC or DBPoweramp for example, with the latest LAME plugin and rip to 220 VBR or 320 ABR if you wish(unnecessary) ), and compare to the original using (good) headphones. You won't tell them apart.
