Since measurements means little to a lot of people, here are some actual A-B comparisons of original audio clips of well-known (and not so well-known) tunes, both in their original state, and after recording into the HVR-V1U's audio inputs and recorded to DV tape. I recommend using a good pair of headphones, or listening through a decent stereo system, as opposed to tiny computer speakers, as much of the missing audio will be in the range of a normal stereo system.
