I've had my SR80s for about a week now and have been very impressed. If I had known that phones of this quality were available so cheaply, I would have picked them up long ago.
They sound great in my budget setup: Fuze --> LOD --> PA2V2 --> SR80
The PA2V2 warms them up in a way that works really well for the music I've been listening to. A 24/96 vinyl encode of Smashing Pumpkin's Machina sounds just excellent, and all of the Radiohead that I've put through them is superb. I can see why the Pink Floyd fans are raving over the SR80s in this thread, as they seem to be a perfect fit for that kind of layered psychedelic sound.
I'm still considering making a buffalo leather headband for them, but the stock band is comfortable enough for the time being. I have a month off coming up and will see what I can knock out.
These phones certainly deserve an appreciation thread. What a bargain!
