blitze,
I'll try to keep this short as this is an amp post.

Being new to the headphone hi-fi thing and only having a pair of koss cans from the 80's before the 501's, I don't have a lot to base my opinion on, but...

They are favoured by classical lovers (which can be a hard to please if not "picky" crowd). My home system as well as a couple of boom boxes I have can bring the volume up as loud as I want but they are lacking in bass and what I'd call over all "pop". They are supposed to take up to 300 hours of burn-in though but they feel so comfortable that I'm being patient with them.

I think they haven't come close to the potential that burn-in time and the right amp will give them, so I'm keeping my fingers crossed and I'll let you know as time goes by and I sample different amps.

If your thinking of headphones as a way of not bothering anyone else with your music, think about a more closed set as anyone in the same room (or if the door is open, the next room!) will know what song your listening to.

Oh yeah, forget about powering them w/ a PC or portable alone. They crave power and will need an amp.

Sorry about that. Blitze was asking me what I thought about my K501's (which I'm trying to get an amp for) and I kind of babbled an answer back.

Another possible supplier for amps - I just came accross Twinstarr on eBay, he's in Canada (good for those living here and unsure about duties and international shopping woes). Sells two models currently, a nicely made Cmoy, for US$90, and a Apheared47 Cmoy enhanced variant with two dual output opamps, priced at US$110. Add shipping to all prices, and he's working on a lower priced version, the Red model that will sell for around 70 US.

The Cmoy model is at http://www.twinstarr.com/twinstarr_blue_cmoy.htm

Apheared model (shown below) is at http://www.twinstarr.com/twinstarr_black_apheared.htm
