My Christmas present to myself arrives tomorrow, a set of Grado PS1000's.   Will they require a "break in" period?   Will they sound different after being broken in?   I have read a little on break in, but I still wonder exactly what happens.   Thanks!

I'm wondering if getting a headphone amp would be any big upgrade over using my 70's vintage monster Sansui 9090DB would be any large improvement. For my ears, the 9090DB sounds really sweet with my Ultrasone 780's.  I'm just wondering what all the hoopla over headphone amps is about.   ...

What headphones give the largest soundstage? Coupled with excellent overall sound, of course.

My thread about a portable amps in that forum has wavered into desktop territory, so I'll ask my questions here, if that's OK. I love the sound of my Ultrasone HFI 780's right out of my iPod Touch 2G, but I know they will sound a lot better through an amplifier. Now for some questions...

Hello everyone. I'm currently using some Sony DJ headphones with my iPod Touch 2G. I have ordered a set of Ultrasone HFI 780's and will have them in a couple of days. What amp would you recommend for home use? I like to lay in bed at night and listen until I fall asleep, so...
