Upsamplers, DACs, jitter, shakes and analogue withdrawals, this is it.

RE: ever read the Moncrieff stuff, or has that been discredited??

To the extent that Moncrief uses theory to show that DSD64 is not as good in the treble, I think he is off base. Furthermore, I don't think it is possible to understand what is going on without a lot of heavy math, which explains how dither works. Moncrief doesn't get into this, nor would this be possible in a popular newsletter.

In practice, I put DSD64 roughly at 176/24 in terms of subjective sound quality, i.e. way above 44/16. However, this applies only to pure DSD recordings, not ones made by upsampling PCM, of which there are many examples. I try to listen to formats identical with the masters to the extent possible, because conversions to/from PCM and DSD are generally a poor idea. (Comment applies to DSD64, not to DSD128 or higher.)

Incidentally, Moncrief was my audio buddy in high school. We used to lug our tape decks, preamps, amps and KLH-6 speakers around the campus of our school so we could listen to symphonic music in large rooms. We were both introduced to Hi-Fi by none other than E. Bradley Meyer.

Note: DSD was a Sony/Philips marketing buzzword. The reality is that DSD64 is nothing but 2822.4/1 PCM. As such it benefits from a high sample rate, requiring no anti-alias filters on record and minimal filtering on playback. However, aggressive noise shaping is required and there is a lot of "secret sauce" to get good sound out of the 1 bit format.
