whats teh price range fo rthr HD 650 and the 600 cans? If I amnot wrong the drivers for the HD600 drivers is the asme as eh HD 580. Are these series comparable to the AKG 501 model or more higher end?

I am also thinking about this. However I cam across the Pioneer PD-6 which also does SACD and mp3. Have you heard this? How would it compare to the SA7001 KI?
