As reported in Jon Iverson's and Kalman Rubinson's review in the September 2008 issue, the Sooloos Source:One, which is the component that outputs analog and digital audio, uses a high-quality soundcard from German manufacturer RME. We didnt have room to publish an interior shot in the review, but I thought readers would be interested in seeing one, nevertheless.
Looking at the Source:One, at the front center you have the network interface card; on the left you have a switching power supply; at the rear center is an industrial PC with its familiar but unused I/O jacks at the front and its vertically mounted RAM board at the back; and at the right is the RME Hammerfall soundcard plugged inot the PC's PCI slot. The RCA jacks at the front of the photo were incorrectly wired on both our samples, with their grounds galvanically connected to the chassis. Jon Iverson's sample was corrected before he performed his critical auditioning
The significance of this photo is that what ostensibly is an audio component is actually a PC dedicated to one specific function. I think this is increasingly what we will see in high-end audio components
