My wife and I have had this system for almost 10 years now, and it still brings us just as much joy now as it did when I built it.
Thiel CS 2.4 SE
Lenovo tiny PC in a case, running Linux and MusicPD
Bel Canto REF Link USB to AES adapter
Ayre C-5
Bel Canto DAC 2.5
Bel Canto REF500M x 2
Some Furman device that's a glorified power strip
We recently inherited an Ayre C-5, so that's in the system. I use a Henry Engineering 3 input 1 output AES switch to toggle between the USB converter and the CD player.
Power cables are various lengths from the endless supply available at a data center. AES and balanced cables are Mogami, bought on eBay.
I got the Bel Canto stuff for a great price back in the day. While it is certainly a bit overpriced - having the components all match is nice.
The computer case is just a 2U amp case from an Italian DIY audio company. The back panel had 6 holes machined in for D-sized connectors. I put Ethernet, USB (one for the AES adapter, one for an IR receiver), and HDMI, with two left unused.
I just had a coaxial driver repaired by Rob at Coherent Source Service. I highly recommend him for any Thiel owners out there.
The walking sticks probably need to find a new home...
