I have detected another strange thing about my Muse unit.
On a specific piano track (Olga Konkova - Album: My Voice - Track3: I Could) - there was an occasional slight "broken speaker"-sound some specific places in the song. I tried with my other headset, same thing same place. Then I switched to my NaimDac - no "broken speaker"-sound! How can this be?? The muse sounds flawless and beautiful otherwise (when it works - but now it mostly does).
If another Muse mini dac owner (SPWild?:-) would care to try out this specific track - pm me your mail and I'll send the mp3.
Yeah I know exactly what you mean. I have two possible theories as to why sometimes some tracks can sound "distorted" in some sections when other Dacs it doesn't seem to be there.
Either other Dacs have the advantage of oversampling averaging being able to extract a more accurate waveform from a poorly recorded digital stream...which means that the NOS dacs are actually more ruthless with poor recordings because it doesn't utilise any form of averaging or error correction or compensation...nothing...bits go in, waves come out with the most direct conversion. I don' rule this out because on the best of recordings there seems to be no problems and problems only seem to be audible on less than perfect recordings, that is most recordings period.
The second theory is this may well be the distortion attribute of NOS that can be measured and observed. This cannot be ruled out, but seeing how NOS sounds so gorgeous, I don't want to believe this...and even if this were true...neither me nor you have heard anything other than the cheapest NOS dac possible. Would these issues be heard on the Zanden NOS dacs for instance? In the end of the day, the saving grace is the fact this thing can teach a thing or two and educate for merely 60 bucks.
Let me know if you want me to still listen to this track, I can compare this to my other DACs no worries.
