See here is the thing, I don't get about people, the 650 is an improved version of the 600. The sound signature can be changed 100 percent if you have an amp with some good tube rolling options. I also recommend the Equinox HP cable as it changes the things people moan about such as the bloated lows or the veil, the equinox turns bloat into amazing impact and brings the vocals forward and if you think about it, that would make the 650 fit closer to the description everyone uses to describe the 600. Start with the best headphone and do some tube rolling and then screw around with cables and you will discover that all those "Its too warm, The highs are too rolled off, the sound stage is too small" reviews are not describing the 650 but describing the 650 cable and their own amplification.
I am listening to the proof as we speak. Natural, Crisp, amazing timbre, and Balanced are words I would use to describe what I am hearing and all that with no fatigue, fatigue is non-existent in my rig. It is now 8:30 am and I woke up at 1:30 am because I went to bed early and I have been listening to these 650's the entire time.
I have 6 different gain tubes, each with its own sound signature and two different sets of driver tubes which gives me a total of 12 different sonic signatures from one amp. They can sound how ever you want them to sound, then the equinox versus the stock cable can make that 12 a 24 if you want to get technical. See what I mean?
Its the whole system, not just the headphones and the amp.
