OK, here is the scenario: You live in a city where there is no CANJAM and can't afford to go to one (that or not acquire a HD800 or PS1000).
A new store opens that carries Denon, Sennheiser and Grado. You can order any model but the demo list is short.
They do have HD800 / 700 / 50 plus Denon AHD7100EM and Grado 325i.
OK, great! I can do some cool comparing, right?
The store has music playing in the background which is also the demo music????? A song was playing that just had a single acoustic guitar playing. OK, so it's good for guitar demo.
I asked for something more lively so he switched to Van Halen "Dance the Night Away".
The source of the music (computer and DAC) was so lifeless that the 325i sounded better than the Senns and Denon given the limp source.
So I can say that I ran a comparison of some super phones but that is it, VERY DISAPPOINTING! Elevator music does not test what great phones can do????????????
