They aren't all that different. I'm still planning (key word here because I've been saying such for sometime - but have got a round tuit) to write a comparison review, but overall the tonal balance is similar. I was evaluating the two for about three weeks before I finally made the decision to keep my TH-900. The decision was pretty easy because they were so similar, and I find the TH-900 to be a tad more fun. If I had to describe the difference in terms of percentage it would be somewhere around 8-10%. Obviously this seems like a rather small margin, but in terms of audio (a game of inches)... that number can be significant to some and vis versa. For me, I already had the TH-900 for a little over 6 months - and I am still loving the sound I get from them. They fit a void in my collection that can't really be replaced by anything currently on the market. I don't find either flawless, but the TH-600 had a few things about it that swayed me towards the TH-900. First of all, the I find the treble on the TH-900 to be smoother. I haven't experienced any sibilance with TH-900, but did experience some with the TH-600 when testing female vocals and some horn/stringed instruments. Not enough to call it hot or sharp, but just slightly edgy. The other noticeable difference was the balance of the bass. The TH-600 lacked a bit of body and fullness in comparison to the TH-900. I would call the TH-600's bass more of a U-Shape, while the TH-900 have more of a V-Shape. Of course this is preference, but I find the TH-900 to sound noticeably more full. Both have sweet mids, with the TH-900 having slightly more recessed mids. This doesn't really bother me, and like I said is a refreshing change from my warmer headphones the Mad Dog and the LCD-3. The TH-900 just sound more natural to me overall, but others could find them both too colored - so the moral of this is obviously preferences. There is more value in the TH-600 no question. At its price, it is hard to recommend the TH-900 over the TH-600 if you are on a budget. They are more similar than they are different. I would be happy with either, but I have the curse of always asking "what if?". Getting the lower model in a headphone lineup would always leave me itching to find out what I'm missing with the top of the line.
I would urge you to try and find a demo somewhere before buying, or buy from some outfit that accepts returns. You could very well find the "upgrade" not worthwhile, or not like the change in sound, either way it would be a good idea to find out for yourself.
