Of those I've heard/owned:
570 < 525 < 545 < FrankenSenn < 600 < 595/650
FrankenSenn is what I'm currently using at work, it's my old 525s with 545 pads and 580/600 drivers. Probably very similar to the 565 now that I think about it. It's my junker pair, but it sounds nice, like a relatively tame wolf in sheep's clothing
The old senns should get bonus points for interchangable parts.
I consider the 595 and 650 on par for my taste because I much prefer the 595 presentation and detail over the classic "Senn Sound" and find it a more enjoyable listen, even if the 650 is technically superior. I only like the 650 on equipment that is beyond my price range - though I also think the 595 actually sounds worse on some high end gear than they do on mid-fi stuff. Go figure.
I've never heard the 590 but based on what I've read I imagine it would place near the 545 by my ears.
The 570 is a $50 pair of headphones, not at all worth what I paid for it way back when, the 525 was a little sloppier depending on the music, but cheaper, more detailed, better soundstage, better bass.
