    Thanks for the interesting links! I was reading the articles rather hastily, so might have missed what I miss: how exactly the auditions were done and if the reconversion to Wave would be able to fix the issue under certain preconditions.

    Since my brief attempts never revealed a sonic difference between Wave and Flac versions of the same recording, my interest was peeked, so I took the logical step: mixing Wave and Flac files together with inverted phases – using WaveLab and Flac 1.3.1 encoder set to highest compression (8) in foobar2000. Test subject was the first movement of Shostakovich's 10th Symphony in 24/96, a DVD-A rip (from DGG), one of my best sounding recordings.

    To be more precisely: The so-called inverted «Flac file» mixed to the Wave original is in fact a Wave file reconverted from the Flac file.

    What I initially found was a distinct «noise floor» of exactly –73.33 dB and one single peak of –52 dB.

    However – mea culpa! – I managed to convert the original 24/96 Wave file to a 16/96 Flac file due to the corresponding preset in foobar2000. :flushed: So please forget my previous findings, and sorry for the false allarm!

    The new graph shows a regular –144 dB ground floor – but again also a single peak, this time of –120.412 dB.

    Now this can barely be the cause of the pretended sonic differences, but it is nevertheless a bit disturbing.

    However, I still can't hear a difference between Wave and Flac. :frowning: Actually in my main (computer-based) system (with M Scaler and DAVE) I exclusively listen to Wave files. Flac is reserved for my DAPs.

    I accuaccident pressed one of last three buttons of HMS and all three lit up. I know there is no use of these and these are for future use but pressing and lighting up these affect the sound quality ?

    Did you hear the sound quality change?

    They are a non cancelable self destruct sequence. Put the MScaler in a bucket of water and hide under a table until the self destruct sequence has been completed. This is a random period selected by the firmware from a complex calculation involving the date of Rob Watts birthday and the number of minutes that the MScaler has been used since 1st April.

    Careful - it is almost guaranteed that some audiophile will read this, and think you were being serious.

    Two weeks to the Munich high end show...Chord rumored to be showing several new products. I'm sure one is going to make use of those spare glowing buttons

    It is slightly stronger than a rumour.
    What Hi Fi have posted "Last year, Chord used High End to introduce both its Hugo TT 2 headphone amp/DAC and Choral Etude power amp, and it looks as though multiple new products will be in the spotlight this year. We've been sent an invite for the launch of "a number of new products". Will we see a new amplifier? Or a second streaming device? More DACs? All will be revealed on Thursday 9th May."

    I would say 2Go and maybe Mojo₂ and maybe more...
  13. lcasadonte
    I've seen a flurry of activity around the poly software that leads me to believe they are getting close anyway.

    Perfect! The 2go comes out at a low financial trough for I.

    I was only saying I bought WAV, because of whatever, if, maybe, etc. (No worry.) I never said heard a difference between WAV and FLAC. This discussion made me re-read what FLAC was about. I knew it was about being lossless and no data lost. After re-reading, I re-read that FLAC is like a ZIP file, and all the data is there. To be honest about that though, I never worked out how they did that.

    As the data is sent from the player in samples, and then Chord DACs re-clock. I can't see how FLAC could sound different to WAV.

    If some other users in reports hear difference, then maybe that because their DACs don't re-clock.
