85% of the PS1000 you say? Someone said the same thing in another review. That's awesome.
Friday cannot come soon enough with these cans. And I'm picking up an old Pioneer Elite CD/SACD player with a DAC built in for 65 bucks.
I love bass, and these seem to be the best Grado's to deliver it, or so I hope.
I for one have said in a previous post, that the PS500 gave me about 80% of what the PS1000 could, after many months of living with my PS1000, i still stand by that claim, as much as i liked the PS500s, i just love my PS1000, if you ask me, you can't go wrong with either of them.
As far as bass is concerned, i believe that is were the PS500 shines, it's deep and fairly well defined.
