The CD player is another issue. I noticed that a lot of reference CD players (such as the Emotiva) are all single disc. I really do love the 5-disc changer and would be hard pressed to want to down-grade (in terms of disc count) to a single disc unit. Popping in 4-5 hours worth of music for the entire evening is fantastic. I noticed Marantz has a pair of 5-disc CD players: CC4001 and CC4003. I am not a stickler for having all the components look identical. The Denon DCM-390 and 290 also look appealing. Apart from the WMA, Mp3, HDCD support these units don't look any different from my Technics.
We typically stay away from changers simply due to reliability. However, here is a list I found a couple of years ago (yes, probably too old), but here you go:

Depending on your budget, what I would most definitely consider in your shoes, is a media server. Something like Sonos, after my initial research, seems super cool. Forget 4-5 hours, go as long as you want . . .
