How much should I bid...

Chasing a 5 year old (decent-ish condition) pair of HD650s which have light use (around 800 hrs aprtly.) I like the sound sig of these oldies.

But how much is a pair this old actually worth? With 1hr left they seem awfully pricey for their age.

Thanks

Some nutters have bid them up to £120 ($185). I hate the idea of buying new Senns. I already have a (broken) pair, I doubt I will like the new ones any more than the old ones, if they are any different I will like them less. I resent having to spend a load of money to replace something I already have. (I know everything I just said made no logical sense)

Can anyone suggest a good pair of phones to replace a HD650 with? You know just to take the sting out of having to fork out £200+ for something I shouldn't have to replace in the first place.

I love classical, have always found it suprisingly underwhelming on my headphones, prehaps playing in an orchestra has spoilt it a little for me. I am a lover of warm sound, I hate even the slightest feeling of "sharpness", completely spoils my listening experience and sense of emersion. The way I perceive "sharp" sounds in real life seems very different to the way they sound squirted into my ears from a driver an inch away, so they seem to stick out like a sore thumb, thus I just avoid. Dark and laid back is the way for me.

My taste for popular music is oddly specific. Bands I like include old krautrock bands (Can, Faust, Neu etc) Portishead, Radiohead, Wilco. Oh and The Fall. Tom Waits.

A few strange and heinous ommisions in the Classic Rock and Prog Rock genres which I barely listen to at all for some reason. All in all not much guitar music so the headphone doesnt have to be great for "rocking out", at least not rocking out to actual rock

The only thing that worries me about 5 year old cans is the fact of buying something second had off ebay. As opposed to new from a dealer, where you get returns and a warranty. Oh well they went while I was busy chatting anyway What a massive waste of time...

So based on my rushed and slapdash comments; any suggestions ?
