My present everyday set-up:
 

 
Modified K500 connected balanced (two plugs), a special trick of the anode/cathode output of the Audiotailor Jade. Terrific sound stage and airiness. GEC 6AS7G (or Tung Sol 5998) output tube, Telefunken ECC808 driver tube (with adapter).
 
 
The standard K500 has a 1/8-1/4 inch plug, and if you've lost the adapter I've found a replacement. Plug and adapter don't have the usual thread, but a larger one. AKG original to the left, Audio-Technica replacement to the right:

Hi, I'm thinking of bying the akg k500, but now I don't have the money to buy a good amp. I have a fiio e10k, does someone know if it's enough to have a decent result? I read somewhere that they need a lot of power.

I Borrowed an AKG K500, and when I had a listen on a Vintaged integrated Amp, of which I did/do add the desperately needed bass from the tone controls. long story short, I have sold my beyer t90s, and I'm planning to smack my hd600 with a price as well, As soon as I find my own pair of these 500s!!!. Im on the hunt

I drive them with an E12. That definitely is enough power.

... same story for me. I'm on the way of selling my HD600. Sold K701 already.
What will stay is K400 EP for Rock/Pop and voices (even opera) and K500 EP for the rest of Classical and some instrumental music.
I still have K501. Not sure what to do with them ...
