I assume this is in relation to the 'absolute phase' question, and the firmware update that fixes it for USB but not optical or coax. The reviews were done before anyone spotted this, so out of the box it should sound as reviewed. As to whether it's 'right' in your system, you'd need to check whether the amp and speakers preserve absolute phase too - not all of them will.
The other question is whether or not you can hear the difference with music anyway. The archimago post metioned by @Tup3x presents it quite well with a verifiable test taht you could try for yourself. In that case at least, with synthetic test tones the difference can be reliably detected in ABX testing, but with an instrument with an asymmetric waveform (so is more likely to be detectable) the difference couldn't be reliably heard. Perhaps with some synth-heavy music it will be audible.
Yes it was related to that point. Thanks for the response.
