Krazeeyk, you are pretty much correct about the process you're about to be going through. But don't feel badly - trial and error is a continual experience for audiophiles with a lot more years and gear under their belts than you. I'm not going to try to tell you what to listen for; that wasn't my intent in bringing that up - rather merely to say that even if respondents made a laundry list of sonic attributes, that wouldn't be any more helpful than a list of design features, or paper specs as you put it. You've just got to start somewhere, and keep listening. Besides, you really can't start right from the beginning with your ultimate system, or even one for a price, without experiencing some different stuff in between through an upgrading process, especially if you're not auditioning beforehand. And I admire you for not wanting to waste the time of dealers if you have no intention of buying from them. You're correct about using Audiogon to minimize your financial risk in trying stuff out in your home.
Anyway, to get back to your questions, I don't know about digital being simplicity (that more describes analog), but I can say that specs and chips and design features aren't necessarily going to tell you much about what a player will sound like. I can also tell you that digital differences can be pretty subtle, compared to speakers or amplifiers (though they don't have to be), and that you probably can't go way far wrong in choosing from among the various moderately-priced options in your range - none will sound like the best, but none should ruin your sound either My best advice would be to try and stick with well-known makers and pretty up-to-date models, just as a hedge if you decide to sell again. I'm sorry I can't comment on the specific model you're talking about getting, but maybe others can. Best of luck and happy listening!
