Several years back I attended an audio demo wherein the system did sound excellent. The dealer asked the attendants how the system compared to real ’live’ music. Some folks came out and stated this system sounded better than live to their ears!
I thought this reply was not correct and showed that those who made the point were perhaps not listening enough to live music, even though it was probably in the top 5% of systems I had heard. Now, if we took a canned version of this system and listened to it via video online, i believe that a few things would be evident. 1) the system would sound only a fraction as good as when heard live and 2) the ability to really determine its quality would be severely diminished. Therefore, personally i give very little credence to the SQ on videos on the web as to how any particular product or system sounds.
