I'm looking for a new pair of headphones and I've read about the Grado SR60i's and SR80i's on Headroom and have heard some good things (not to mention the killer styling). According to Headroom, the 60's sound really good without an amp, and don't improve much with one, while the 80's don't quite reach their potential without one (although I'm sure they'd sound better regardless). I plan on using the headphones both from my ipod and laptop with and without an amp.
How will they sound comparably with and without an amp?
How is the bass response?
The price difference isn't a factor for me.
