CD copy question

If I burn a copy of an HDCD-encoded CD, does the HDCD coding get copied? How about XRCD processing? Single-layer SACD?
Yes, as far as HDCD or XRCD.
Yes, agree, the encoding is part of the code, not some added on thing. It always gets passed on. All that matters for HDCD is the decoder has the HDCD decoding ability. XRCD is a different encoding system, and once done , that is the datastream. It is gonna be the XRCD.
If you use a computer but not always with a standalone copier. A standalone will also remove any meta data that's on the disc.
