For those that listened to both HD 650/6XX and the Massdrop HD 58X Jubilee enough to form a fair opinion, would you say that the high mids/low treble are more relaxed on the 58X? I owned a new HD 650 for a couple of months a couple of years ago. I found that at times, depending on the artist/song, the mids were slightly too forward/bright. It was actually bothersome enough for me, that I would stop listening after a while. Again, it wasn't terrible by any means, but I think I'm sensitive to this general frequency range. Curious if the 58X would be better for me.
Also, I've read comments that the 58X sound grainy, which I don't like. I loved the smoothness of the 650. Is the grain really that noticeable on the 58X?
Thanks in advance for any sound advice.
