Try Audio Technica ATH-ES10, ATH-ESW11LTD, ATH-W1000X, W3000ANV, W5000, etc...
Or Denon D2000, D5000, D7000
Or Mr. Speaker's Mad Dogs (same price as K550) w/ some good source/amp combo
Or if you want to scale even higher, Fostex TH600, TH900...
Those are all closed-back headphones. Pretty much every open-back headphone over $200 MSRP sounds better than the K550 IMO.
You know, Bill-P, you really make me regret not trying the TH900 at the meet.
