Par contre, est-tu sur d'écouter à volume égale sur les 2 systèmes ? Dans les mêmes conditions ?
Cf les explications du concepteur chez Chord, dans la FAQ d'HF.USB connection making a difference to sound isn't data related - its down to RF & correlated noise

That is not the case with Chord's windows drivers. If faulty data is sent through, then the DAC requests a repeat, and so ensures perfect data transfer.
It is possible with all other OS; but having said that, the data failure rate is very low (otherwise DoP would not work).
The USB connection making a difference to the sound is not data related - its down to RF and correlated noise (not jitter as this is completely removed too) - take a look at my previous posts if you are interested.

The reasons why sources and digital interconnects sound different are well understood - see some of my posts. In a nutshell it is not jitter (all my DACs are source jitter intolerant) but down to RF noise and distorted currents from the source flowing into the DAC's ground plane. The RF noise inter-modulates with the analogue electronics, creating random noise as a by product, which creates noise floor modulation, and that makes it sound brighter or harder. The correlated or distorted currents very subtly add or subtract to small signals, thus changing the fundamental linearity, which in turn mucks up depth perception.bavinck said: ↑
I don't think anyone will ever answer that question satisfactorily if you know how the technical aspects of the devices work. The transport is passing a purely digital signal onto the Mojo, just what the original file is. Mojo does all the work. That being said, some people swear they hear a difference in sound depending on the transport. You decide what is most likely:)
But I also agree in that lots of people hear changes that are not there - I for one have never heard any difference with optical cables (assuming all are bit perfect) with my DAC's, but lots of folks claim big differences. Placebo, or listening with your wallet, plays a part here. Then there are cases of people preferring more distortion... Listening tests must be done in a very controlled and careful fashion, particularly if you are trying to design and develop things.

Pas folle la guêpe, faudrait pas sabrer les ventes du Mojo 2 ou du Hugo 3.
Du coup, ce sera sans moi pour le Hugo 2.
Mettre ce prix pour un appareil dont la batterie sera morte au bout de 4-5 ans, pour l'usage que j'en aurais, aucune justification. Et un point de plus pour les sets sédentaires, hélas peu mobiles.
