What?? 30 dB S/N ratio is within spec??

How much is this in volts? Is a CE sign on the device?

Balanced outputs, but 30 dB S/N? Unbelievalbe.

This seems to be common practice nowadays :-((
I noticed that on the Santana Supernatural CD. Imagine that... a
bestseller, and just clipped (heavily sometimes). The clipping is not
audible to me (and appearantly not to others either), it happens mostly
at drum hits. But it's clear to be seen on screen.
And people are worrying about higher sampler rates/higher resolution...

Perhaps you have better speakers at your computer than at your Hifi? ;-)
