I guess there isn't too much difference between watching U-Tube and following internet forums when it comes to valuing comments and advise, or for that matter making comments or giving advice. Whatever floats your boat, its a personal choice made for reasons mostly unique to the individual. Don't watch if you don't like! You really don't need to piss on others for their beliefs. :-(
Why on earth?
Answer me this: On You-Tube, there are endless of reviews, comparisons, and demos of equipment played in the creators room, recorded by a mic and published as if we could hear anything relevant considering we are listening to OUR stereo! Some of these have high play counts. Does anyone think they could hear differences in an amp or DAC picked up by some unknown mic, A2D, post processing and played back on their HT? Are we really that stupid?
