How big is 8bits of dynamic range?
In what sense?
To determine the effective bit rate necessary to fully capture the information on a vinyl LP, you need to know the bandwidth and the dynamic range. A typical vinyl LP has a bandwidth of about 18kHz (when it's brand new, it might get up to about 22kHz). There is certainly some audio stuff above that, but it generally bears no relation to meaningful programme material (ie. it's noise and distortion). So let's be generous and assume a bandwidth of 22kHz: you'll need to sample this at 44kHz. The dynamic range of a beautifully pressed LP on virgin vinyl can get to about 65-70dB on a good day with a following wind, which equates to slightly less than 12 bits. So the bit rate required is 44,000 x 12 x 2 (for stereo), giving about 1030kbs. A more typical LP (18kHz bandwidth, dynamic range of 55dB) needs a bit rate of about 650kbs. For comparison purposes, the CD bit rate is 1378kbs.
in the sense that this doesn't mean a lot to me because i have no idea what music is supposed to sound like:
and I don't mean in a "a good song is a good song mate" way, I mean, how much of this can people hear? Are we talking just an academic difference that computers can measure (and a few people who want to show of their exceptional hearing)?
How many kbps am I hearing when I strum my guitar?
yeah but
Life man. LIFE.
well someone thinks it sounds better

DVD has a bigger range than CD. It matters more in terms of volume range detail than sound quality though.
Of course!Beatles ones
This is true. However - and this isn't aimed at you, it just reminded me to add - this whole conversation is about potential. Having a recording with no dynamics and sticking on a DVD won't add dynamics. However, if you have something extremely dynamic you won't be able to properly catch some of it on a record/cassette.
The sound will get lost in the noise floor sooner than on a CD/DVD.
