SONY NW-WM1Z / WM1A

    That oriolus thing supossadly hisses.... That's unfortunate, at least I can rule it out. 3.0 /1z is amazing at a micro hiss. Basically not there. Even with sensitive iems

    First tentative not very conclusive: used the SE output of the WM1A wired into Jotunheim input (cable jack 3.5mm to RCA)
    I compared the same track with the WM1 as source and the the Modi Multibit, on a Focal Clear (balanced output)
    WM1A sounds dimmed (although volume on the DAC was set to 120), and super flat, without life, completely different from what I get directly from the output.

    Not sure if the SE input to Balanced could mess thing up. I was just curious.
    I'll try the single ended cable I got in the Clear box and see if it helps.

    More tests soon.

    Never mix single ended and balanced, only single ended to single ended and balanced to balanced

    You might also try hi gain output on your WM1a.

    I took my favorite test your headphone playlist (mix of rock, indie and electro, all FLAC, some hires)
    Test below all done in single ended mode.

    1st session with the WM1A in DAC mode, wired into the Jot with jack-RCA cable
    WM1A settings:
    - Low gain
    - volume to 120 on the DAC
    Amp settings:
    - 10 o'clock on the amp

    2nd session with the internal multi-bit

    9 o'clock on the amp, still wow effect, this combo gives me goose bump

    3rd session with the Clear directly in the DAP

    WM1A settings:
    - Low gain
    - volume to 60 on the DAC
    Definitely better than in DAC mode with amp

    Summary for this quick Single Ended test:

    Modi Multibit module + Jot + Clear >> DAP - Clear > DAP in DAC mode + Jot amp + Clear

    I tried, it helps matching the level of the internal DAC (almost) but the overall signature has nothing to do with the internal multibit DAC which is a much better combo with the Clear, crispy details, punchy, great separation.

    In the office I tried to pair the DAP with my old Fidelio X1... it is definitely better than my existing DAC (Audio Engine D1), I am gonna sold it for this very reason :)

    Talking about low distortion, I have never seen any measurements for the Sony Walkmans 1A/1Z. They could only have a SNR of 85 for all we know, has someone personally measured jitter etc?

    (Yes I know it doesn’t determine sound quality, but I’m still interested)

    There are charts and measurements several places within this thread

    For line out i do High Gain and maxed volume

    Same here! Love my 1Z as a source into other amps.

    Exactly......

    Though to each his own. Best part is everyone likes the versatility of the Walkmans.

    So then you found it was 50/50? Out from the 1A was better than the D1 making a line level signal for the amp, but in other cases.......no?

    At my office I used the WM1A as DAC and Amp, no external amp, WM1A has no issue to move the X1 (30 ohms).
    The Clear is a lot more difficult to drive (even its only 55 ohms rating), and thus even with the high gain.

    So as a line out/pre-amp with WM1A Single Ended, high gain or not I am not convinced. It works and you'll need to push the volume on the external amp compare to other sources.
    I'd love to try the setup fully balanced, I don't have the cable 4.4mm to double 3-pin XLR and don't plan to get one unless someone has one to spare.

    Totally agree on that, this little thing has so much potential now it can ruin ppl just on cable :)
    I am really delighted Sony made this move, I too invite folks to try around, the 250 mW (vs. 60 mW) on the balanced output should make a big difference on line output.

    Guys,

    For the record, I'm using this cable from my 1Z to a Qimpu A6000 amp in the office, (when no one's around) and to my Mystere IA21 at home.
    I'm happy as pig in slop!!
