Want a nice Senn closed back? Sennheiser made it before the HD580, and even reissued it over a decade later. HD250 Linear and HD250 Linear MkII. My 600ohm Mk1 has the same mid-range magic as the 600/650. I feel it also has better treble coherency and balance, and it has better bass extension and quantity. The driver tech really is from the same era, yet people continue to put the 580 series on a pedestal. Perhaps deservedly so, but many classic get overlooked.
The HD250 Linear has an easier going balance than the 630VB. It has detail but is infinitely listenable like HD650 and LCD2, but with more air and bass presence. HD820 won't even sound like it
HD630VB is more tuned, though still is fairly linear overall. Has some stylistic dips to separate bass and highs. Also, happy to report, that it is becoming much more comfortable after some use (the headband is clampy like many Senns). It's a bit like carrying around a portable LCD2 - both in weight and quality.
