You're talking in absolutes, asking if it's "great" or "bad". That's quite a range!
Actually the Shanling is more middle of the road. But hey, it's pretty, and that's all some people care about. It looks good and impresses people who haven't heard the really good stuff.

And what would be the good stuff?

I suppose since a lot of what I read about the Shanling often refers to the Parts Connection modded unit that perhaps your middle of the road comment(needing some help to reach higher) might be right on.....

I'm rather familiar with the Shanling's sound (not modified), and find that it's a solid buy. Like most solid buys, you'd have to spend significantly more to justify spending more. It doesn't do anything annoying, which is good, and it's easy to listen to. It's emotionally involving and resolving enough to give you chills. I'd say, therefore, it's a great player, unless you only want to own very expensive, no-compromise players...then it would certainly be a compromise.

It's hard to say why so many newer products end up on the used market; but I don't think it always correlates with an absolute sense of the product's sound.

Good luck
