I'm not sure I follow you.
Bits per sample is what determines dynamic range.
CDDA uses 16 bits/sample, and that gives a dynamic range of 96dB.
Vinyl records have a varying dynamic range depending on several factors, but it's usually between 60-80dB (equivalent to about 10-12 bits/sample).

Samples per second (or sample rate) determines the maximum frequency of the recreated signal (half the sample rate, according to the Nyquist theorem).
CDDA uses a sampling rate of 44100Hz, and that gives a maximum frequency of 22050Hz.
Vinyl doesn't have a real frequency limit, but is usually cut off around 20000Hz (by a brick-wall filter). Both to prevent high-frequency noise from being audible and because of the engraving process.

So how are 16bits and 44.1kHz not enough?
