Well, we know some hiss is there but that is inevitable and was never in doubt.
What we still don't know is (a) whether this is within the design parameters of the phono stage, i.e. considered acceptable by Devialet, or (b) whether there is significant sample-to-sample variation between supposedly-identical amplifiers. The latter might explain why some people find it more objectionable than others, but it could equally be due to differences in settings and/or personal taste/sensitivity.
Based on Mathieu's responses to @Confused's recording it seems he is not perturbed by what he's seen in that example, at least, but apart from that we haven't much to go on.
To make further progress, Mathieu has been clear that anyone who find the hiss a nuisance should get in touch and send him recordings; this would help establish whether (a), (b), both, or none of the above applies.
