Is there another brand other than Sennheiser that would have to Sennheiser's angle drivers on the H700/H 800s virtues of soundstage depth without that very pricey price? And also have sufficiently high impedance to be appropriate for a tube headphone amplifier like the Little Dot MK IV with SE better tube option
There's a reason that the HD600's have been at the top of the heap for so long and Sennheiser doesn't discontinue them, even though the HD650's were supposed to be the replacement. I spoke to someone at Sennheiser's US marketing team about 6 months ago and he said that they were considering to stop making them but too many customers were not happy with the idea and the orders just keep coming in. Try not to be swayed too easily by everything people say. Try to go where you can listen for yourself.
