part of the reason why vinyl sounds 'warmer' than CD:
There are certain high frequencies and levels of high frequency that just can't be cut to vinyl without distorting. Therefore any (Decent) cut to vinyl will take out these frequencies before cutting, otherwise you'll be left with nasty hi end on the vinyl. EG horrible sounding tamborines on a fair few records i own
With a CD you burn any (audible) frequencies you want, so theoretically you could have a massive resonant hi hit at 14k in a tune, and obviously it would still burn and play. It's just that on a system it will sound shit and probably painful
It's just a question of production approach if you are playing off CD. And of course the fact that dubs and vinyl go through a mastering engineer before being cut obviously helps
