    i'll test it with senfer ues ASAP, which is very similar to senfer 4in1, and you will be able to check the result.

    Hi this may be a silly question but what chip does this use to process ? I can see the OpAmps but not sure of the Chip? is it NOS? i.e. is there pre-processing before it hits the OpAmps
     
    Thanks

    According to the results it´s not the best choice, just in a strictly analytically sense -unless the case that the measurements are wrong or the unit measured was defective-

    Ok ordered Silmic II 10uf 25v to replace the stock R3A 10uf 16v, Also got Vishay BC 150, supposed to be good also (for 1000uf)
     
    Just bear in mind that the lower the ESR the more transparent the sound is, and for some people this won't mean a good thing. If you want to keep more of a fun sound sig but still improve over stock then Panasonic FC is a good choice for the 1000uf, or Nippon Chemi-Con KY.
     
    Tomorrow I'm soldering in 2x 100uf 16v Nichicon FG.

    Oooh my Walnut V2 is in the US now.  I must start converting my FLAC to WAV in preparation.

    Awesome! If you ordered via AliExpress don't expect tracking updates! Mine just showed up one day.

    Release the wav

    It is a system on a chip (SoC) so not your traditional D/A IC. In other words, not NOS. However. The designer is not disclosing what the SOC used is, one would assume this is to keep others from using it or trying to keep their price lower to keep Walnut more affordable

    What is not known is if the mp3/wav decoding scheme is built into the SoC or if it is done in software.

    So any pre processing is done in the most analog form. Just how caps, resistors etc affect it.

    Most things are SoC these days, especially small stuff. But sometimes if you open a big box there is a lot of air very little electronics.

    Commercial grade processors are the same way, one or two boards with components and a whole lot of air!

    Yup
