Looking for a good Stevie Wonder CD

I remember playing Stevie Wonder albums on vinyl (and even cassette) a long time ago and thinking that that's why stereo systems exist-- to reproduce something like that. As such, I have been looking for a reference caliber Stevie Wonder CD, but from what I've read in the Amazon reviews, most of the re-releases of his CDs don't sound that great. The one CD that I do have, "The Definitive Collection," doesn't sound that great. I read that the Mobile Fidelity release of Innervisions was good, but I would have to buy that used (since it's out of production) and the prices are fairly steep.

I'm hoping that someone out there who is familiar with his recordings could recommend a CD or two?

thanks,
mike
