I've had my M50s for a couple months now and love em. I'm currently running straight from my computer's onboard sound. This summer I plan on upgrading my source and it got me thinking. What is a logical, significant upgrade to the M50s? I want closed, full-sized phones. I thought about the Denon D2000s, Beyer DT770s, and Ultrasone HFI 780s. I really like the sound signature of the M50s but just want more. My only criticism of them is maybe the mids are slighty recessed sounding. Not sure if it's the phone or my source or lack of amp. All suggestions welcome.
