New DVD-Audio music releases and talk about the latest players.

here is the best I can do right now...

I've been digging around the Stereophile charts and the Sony specs. The spec for the SCD-1 is 105 dB dynamic range in the audio band, presumably up to 20 kHz. So I looked at the review of the SCD-1 and here is the link to the graph, not with a 1 kHz digital signal but with digital silence. This shows the rising noise characteristic, but it also shows that it stays below 105 dB all the way up to 20 kHz. It is just below this at 20 kHz. Seems to me this is the way the noise spectrum is designed to look. This would agree with the spec.

OK, why does the 777 graph not look like this? I would think it should. I would think that machine is operating out of spec and should be repaired. I don't think the noise is designed to be as high as that shown in the graph.
