Welly: you should put that in your sources list in your profile, you only have the 470 listed.
The 570 was my first real portable, I really like the no frills aspect of it. For the money, I think it's a very good player (75 used). However, it must be stressed that you really shouldn't use it as your home player. Investing 120-150 for a new Sony NS500V was probably the most effective upgrade for me, and I can still use the 570 for portable use. I was using the 570 as my only player for about a year, a little less, with markertek IC to CHA47 and ER6s.
Investing some of that $1400 dollars in a better home source would have been a much better choice to, say, 150 dollar cables or something. There really is a huge difference.
See profile to see equipment used.
edit: In hindsight, it was kind of cool being able to say that I could take my setup damn near anywhere. Of course, that doesn't mean that it would be as good as a stationary one.
