Not to get too far off-topic, but the CD-1 was the first CDP by Simaudio to use what they claim to be their own transport, right down to the software. The only other CDP that they have made based on this new architecture is the new CD-3.3, so that can likely be considered to be the only Sim CDP that "builds" on the CD-1. There's also a CD-.5 that has just come out, which likely takes some away from the CD-1 (and seems to signal that Sim is stretching down to an area of the market that normally belongs to Cambridge and Rega).
I haven't heard any of the CDP's in this new series.
