Telarc is the only company I'm really aware of that does their studio recording specifically with the intention of creating high quality discs, both SACD and Red Book. It doesn't do any good to take something originally done for PCM and then just stick it on SACD to get a multi-channel mix.
I'm also going to guess fibreKid has at least some decent gear to hear the difference, but you'd really want some good gear to clearly hear differences. I don't think I would be able to hear much difference on say an $800 receiver and $1500 speakers, but move to a $3k pre-pro and $8k speakers and it's a new experience. (Retail prices.)
