Hey Arny, I wouldn't complain about 96.3 dB being rounded to 97 dB instead
of 96. It's SpectraLabs output after all, and none of YOUR measurements seem
to be calibrated or traceable to any National standard from what I can see?

This I have no argument with, I am sure such a cheap card does not have mega
strict quality control. Would you expect it to?

For the record I think your tests are a damn sight better than nothing,
which is pretty much what else is available. And I do read them and
appreciate having some data on cards that I have no access to. Do you really
need to make such ridiculous statements though? 1 dB measurement error is a
hanging offence? 1 dB roll off in a card at 18 kHz makes it useless? 83 dB
S/N ratio is inadequate for recording vinyl or cassette?

Give it a rest. You're destroying your own credibility.
