are all sacd players the same?

A little technical help for the unenlightened please. I f i want to add another sacd player(i have quite a few discs) does the actual quality of the player matter as much as the ability to play the format? I know that a cd dac at 1000$ is going to be pretty different than a Berkeley or similar at 5k. the question is whether those types of rules hold true on the format change. (Is an oppo sacd going to sound significantly worse than an ayre, for example, at 6k.) thanks mike
