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

I will need to think about this...

it is not at all clear to me what information is being presented here. The difference between the top and bottom chart is the presence of a dithered 1 kHz tone. This has effects I do not understand. At 10 kHz, the "digital black" is about -110 dB for SACD and about -120 dB for CD (CD is better by this measure). With the tone, the 10 kHz numbers are still -110 dB for SACD but up to maybe
-108 dB for CD (now SACD is better at this frequency). I don't know what this means. JA seems to refer to the chart with the tone when he discusses "dynamic range". I will need to figure out what tests they are doing and what they mean.
