I'm using my SCD-1 as a transport for "redbook"...feeding an Electrocompaniet ECD-1 DAC via the Illuminations D-60 cable. The SCD-1 is a very fine transport, and the ECD-1 achieves great synergy with it. It's a considerable improvement over the SCD-1's "redbook" playback, and often rivals SACD playback.
Highly recommended.
