I can only guess at what a sound card with linearity specs approaching those of the AD kit would cost, and it's still AC coupled, and as Poul pointed out, has no long term stability spec.
This *is* an issue.. the audio ADCs have great performance in the "sub 1 second" sort of regime.. small variations in gain or offset would have no impact on audio applications, but would be a problem with the EFC measurement..
To me, it sounds like a no brainer, pun intended :) Alternately, my last HP3456A cost me about $50, and that's a 6 digit DVM with decent specs. You will need an HPIB controller though, if you do not already have one.
