sr225 upgrade from sr60, will this be enough...?
Greetings

As I have been reading in this thread, the sr225 will need an heapdhone amp to be driven. Currently, my setup consists of 2 things, using the SR60 Headphones :
iPod + HeadRoom Total AirHead amp
Laptop + Echo Audio Indigo I/O Soundcard, not using the AirHead amp
The reason I am not using the amp with the Echo Audio soundcard is that I did not notice any difference in sound quality. The Echo soundcard must already have a good amp built-in. In fact, when using the amp with this soundcard, I felt the sound was getting muddy.
However, with the iPod, it's a wooorld of difference...
So now I am contemplating getting a pair of sr225, and I am wondering if anyone has experience using the Headroom Total AirHead Amp with these, if they will be enough to drive them?
Thanks!
