Right now the rack is kind of a mess, but I've been thinking of shooting some pics at some point for audiogon anyway, so mebbe that will come in the new "official mac pics" thread. Just seems like its never quite "done"... As far as mini Mac integration, it actually kind of stands out. Except for the ugly SA82509, all of my stereo gear is black. The equipment racks/shelves are black. The Panny plasma frame is black. The mM is, er, *white*. What I really need is the special U2 edition of the miniMac.
The Waveterminal is pretty sweet. In various systems, I've used the Stereolink, the Sonica, the Transit, the Edirol UA-1D, and now the Waveterminal. Head-fi has a huge amount of info on computers as sources. That said, I didn't like the Sonica/Transit (they are basically the same) as much as they did. I always thought the Edirol sounded better, even though the M-Audio stuff preserves 44.1 kHz sampling rates and the Edirol relies on some software conversion to 48 kHz. The Waveterminal sounds better than the Edirol to my ear (U24 also preserves 44.1 kHz). Its pretty subtle as a distinction, tho', and I'll caveat my remarks by noting that the Sonica/Transit family apparently respond well to power supply upgrades and the use of better components in the signal path. The other thing is that the U24 has a 2 channel DAC built in, but that won't help with DTS/Dolby 5.1. Can't vouch for the sound of that part of it tho'--I just use the coax PCM output.
The U24 also is in/out, unlike the Sonica. I think the Transit may allow digital inputs. Guess that might be fun for some who want to record analog sources to the Mac. It is a well built unit, that I will say. Got some heft to it for its size. Does not share any aesthetics with the Mac family, but its easy enough to stuff behind another component on the rack.
