RE: DACs using SPDIF are broken by design

My comments about SPDIF stand. The design is defective and inappropriately cheap. The use of multiplexed clock and data creates jitter problems that would simply not exist with a dedicated clock line, "for example with I2S. Better is for the clock to originate at the DAC. This is an option with I2S. It is possible to build good implementations of a poor architecture that beat poor implementations of a good architecture.

The complexity of USB (A camel is a horse designed by a committee.) makes implementations in DACs noisy unless extra cost is spent on power supplies and isolation. It also makes it likely that many implementations will be poor, if only because the designers attention span isn't long enough to take in the entire specification. (I found it very time consuming to get an answer to a simple question from the USB specification.)"

You are talking theory which is fine, but many are using UBS-SPDIF with positive results. Sometime it is hard to mix theory into practical discussions. Some do not differentiate the two.

You were just told by the streamer cognoscenti not to be discussing ADCs here... Get with the program Tony!!! :):)
