My top pair I use right now are the Denon AH-D7000. They're great for just about all music (including classical) but I sometimes see myself using the HD595's I have every so often to play some classical pieces. So the simple question is for classical music (no jazz I don't listen to that) would you recommend the HD 600 or the HD 650? I've listened to HD650's before plenty of times but I hear from some the HD600s are better. Thoughts? I'm open to suggestion for a cheaper alternative than either of these two for classical. AMP/DAC is Audio-GD FUN so I feel I have enough "juice" to power either of those Sennheiser's.
My plan is to get rid of the HD595.
