- Er...
- I'm not a digital-basher by any means, but modern analog recorders
- with Dolby-SR actually have a sligtly _wider_ dynamic range than
- 16-bit digital recorders. Even the 'semi-pro' Dolby-S multitrackers do
- easily as well as their 16-bit digital counterparts in that respect.
- In real life, microphone+electronics or recording locale noise is going
- to dominate anyway.
- Nor do the analog recorders display the low level linearity errors of
- many 16-bit digital recorders in use. (Try the Chesky sampler for a
- demonstration of the audible effects of that one.)
-
- Dolby-SR and Dolby-S also pushes modulation noise and asperity noise to
- very low (insignificant?) levels.

- What makes you think that there is generally higher frequency music signals
-
- present on the LP, compared to the CD of the same recording? Consider the
- frequency response limits of the mikes used, the electronics in the chain,
- the digital and analog recorders, and the LP itself. Even in an all analog
- recording, it would take a small miracle to actually get accurate
- supersonic
- information from the performance -> out of your loudspeaker. In real
- life...
-
- But do the test anyway! I know I would!
-
- If you think you hear a difference,and post about it, I'm sure rec.audio
- will supply you with a barbeque the like of which you've never seen :-)
