Here's a tip for those who hate cable spaghetti and find it irritating that they've got to use a pile of RCAs for analog output from their DVD-Audio or SACD player....

Monster MicroXLN. Intended for car audio applications, you can get them in 4 channel and 6 channel models. The nifty thing is that you can get 6 analog channels in a cable the thickness of a typical good single RCA cable. The connectors are also very durable but very small. Use a pair of the 4-channel models for 7.1. Induced noise levels are very low; they're meant for a noisy environment. However, I don't know what the crosstalk looks like. I use a 6-channel one in my car and love it (Alpine CDA-7878 to Alpine MRD-F752 to MB Quart components and a Sunfire subwoofer). I'm going to try some in the family room for SACD soon, in the interest of less cabling behind my gear.
