I've read what I could find in other threads about the differences between the two and thought I would pose that question here to get some more input. Thanks!
Well, the HD-580 is quite good and if you get both and over-analyze each of them, you'll find some negatives about the HD-598.
The difference for me is that the 598 has more treble, less bass (including low bass extension), less forward upper mids. The mids in general sound more forward though.
HD-580 has more mid-bass and often sounds clearer than the 598 with specific music. The 598 is a little more grainy, but it's hard to spot. I actually think the HD-580 is clearer than the HD-600 though!
To make things worse..the 598 sounds clearer than the HD-600 to me. Weird isn't it?
Detail level is about the same or very similar. HD-580 with a good DAC might have a slight edge.
The one thing I like more about the 598 is that it seems to have a more forward sound. For ME (and my music) it's a little more fun and engaging to listen to. Of course someone ideas of "fun" could be extra bass.
For me it's a little extra treble and some forward mids. Despite the 598 being more forward sounding than the HD-600/580, it's quite well balanced and smooth sounding. Don't ask me how they pulled that off!
The HD-580 also of course benefits more from an amp. As long as the 598 is properly amped, it's sound doesn't seem to improve much when switching to better amps.
Then there's the soundstage. The 598 has the HD-580 beat easily. It's much larger. I think the HD-580's soundstage could possibly be a little more accurate and have better imaging, but i'm not 100% sure of this (yet).
I love both so I stopped comparing them.
What's nice too about the 598 is that you can use it around the house easily! No amp required at all times.
Right now I can't decide which headphone I like more..580 or 598. I'd take even the 598 over the HD-600 any day though. BTW if you use the HD-600 grills on your 580 these descriptions are a bit off.
