How do those two compare to the master recording? Would the master have the same bandwidth and dynamic range as the CD or SACD, or none of the above?
For reference: the dynamic range on my Marvin Gaye vinyl pressings are the same as on the CDs.
1) Its deduce, deduct means to take away, okay that works here as well
2) Theoretically the CD is limited to 96db and 22.05K - the SACD and DVD can carry more - whether they do or not is up to the mastering and engineering and so on
3) Dunno - depends on how well the transition from tape to playback medium is done
4) As I understand it if you have 70db actual dynamic range then a medium that gives you 120db will deliver er 70db, but I may be wrong, to me it looks like doing a 2400dpi scan of a picture that was printed at 1200dpi, you cannot gain any information, you can just put stuff in gaps created by the resampling - some would call this guesswork others call it interpolation.
5) We dont know the actual DR of the recordings used in the tests, that would be interesting, however , if you have recordings with real 120db dynamic range you are either going to have serious hearing damage if you listen on headphones or seriously pissed off neighbours if you listen on speakers
