All digital wiring is with AES cable. This is simple as it is controlled by international standard at 110 Ohms impedance. A standard apogee wyde eye cable with do the job.

For analog wiring, I use the method described by Chris from VH Audio using 28G silver wire in a balanced configuration. I modified the technique a bit by placing the ground away from the signal conductor. This is achieved by wrapping it with teflon tape – cotton tube – teflon tape configuration.

Please find the following flow diagram for the actual wiring

Update 2011: Since Metric Halo has updated the firmware for ULN-8, there is no need to use passive preamp anymore. I can easily control 8 channels together insider ULN-8 and the Apple remote control works as well!
