Well, I guess all I can do is give the DT250-80's a shot! If they don't work out, I'll just go back to the M50. I read the Headphone impedance article and it says the headphone impedance should be 8x or more the output of the amp. The output impedance of my stereo receiver (Technics SA-200) is around 8 ohms, I believe. I'd think the headphone jack would be around the same. The crazy thing is, when this receiver was new, most headphones had an 8 ohm impedance!
The reason I got the DT250 is because I returned my M50 under guitar center's pro coverage extended warranty plan for dried up and crappy ear pads. It's crazy that they only last a year. I decided I'd give another brand a shot so I went with the beyers which have the velour and are made in Germany. BTW, does anyone have pets? Does pet hair stick to the velour?
Edit:
Just playin' around with frequency response graphs and I found two other headphones that have nearly identical sound signatures; Sony - MDRv6 and the MDR-7506
