Yes on both counts - but with caveats.

1. The signal will not be captured perfectly. One needs to define how 
accurate a capture qualifies as success.

2. The higher the frequency, the lower the accuracy of capture. The 
higher the amplitude, the more likely that artifacts will be detected.

3. The detector (stylus, cartridge and preamp) are sources of 
imprecision in matching input to output.

NOTE: Ringing can be eliminated by rolling off the highs - another 
source of inaccuracy.
