Sony 555 vs. 333 as transport?

Without doubt, I would go for an S9000ES. It's not what you asked, but that is my advive. T

Thanks. The reason I am asking about these two SACD changers in particular is that multi-disc ability it important.

I belive there about the same transport. I would wager that soundquality from each as a transport is probably pretty indistiguishable...but then you could buy em both and return the one that you didn't like! heck, I think "Good Guy's" electronics store sells em both, and they have a 30day money back garantee. How can you loose?

Assuming the transports are about the same, if you ever want to try multi-channel audio later, the 555 offers that capability. I just bought a 555 a few weeks ago and I am checking out multi-channel audio. Pretty impressive, but the software supply is very limited. I use the 555 in a 4.1 system.
