    I got myself op amps LME49860NA, OPA2227P and JRC2114D, they sound good in the Walnut. Its just pairing/synergy with the correct pair of earbuds to get the most out of them.
     
    The Sony E808+ earbud for USD3.80, Surprisingly, its easy to pair with the walnut/ different op amps, other DAPs and handphones. The SQ are with Clarity, detail, good sound stage, easy to drive, good mid, treble and bass (with low sub bass). excellent for light music (vocal). At times I thought I was wearing a pair of cans. The cable are J type one longer than the other that the drawback I dislike. I am thinking of recabling them.
     
    Philip SHE3800 USD3.80 earbud which is equally good. These two are my fav. now. I first heard about them in the DIY thread and I can't get them locally in the shops could be out of production.
     
    For those who are interested, I bought them from the below links.

    That ali add is a little perplexifying. The bottom pics seem to show the MH750Z. So what exactly do you receive when you order these?
     
  3. dennisopk
    The Sony 808E+ Black earbud, the MH750Z is an IEM. green or orange. there is an option to choose either E808+ or the MH750Z when you buy.

    This is a great earbud, i have never recabled my SHE3800 or tried to mod it but apparently it mods great. However the yinman 150 is a more refined version of the she3800 sound. Still, the she3800 is one of my top budget buds,.

    LOL. I think that means you buy too many headphones... I hope to see more non-black ones in your next photo! :)

    I think this is not good for a dap or amp. With all phones connected, this will overload the device and cause damage.
    I will suggest a better way to do ab compare is to use a proper ab switch to switch out the rest of phones not in use.

    I strongly recommend against using parallel connected headphones. Especially on the Walnut the load VERY much effect sound signature. That is why some IEM do not work at all with it while others sound well. You will not be able to compare anything with this setup.

    It's a shame the Brainwavz AP001 isn't cheap anymore.  It was useful for side by side comparisons, but it was a bit bass-centric.
     
  12. bzfrank
    You cannot compare with anything active in between the DAP and the headphone. From the description of the AP001:
     
    "OP AMP for powerful and clean volume, with bass enhancer"

    Everything colors to some extent, including the dap.  As long as the only changed aspect is the headphone, you can at least to some extent compare differences in the end result.  The point of the AP001 for simple comparisons was its two headphone out jacks and the cost.  The Mojo is a better source for this, but is also more expensive.  I mean ideally, you shouldn't be comparing unless you volume match anyways, and many people do comparisons by estimating volume matching or not doing so at all, and this will augment the results.  But it's not realistic for every comparison to be taken to this extent.
     
    And on a side note, quoting advertising text never really ends up being helpful as you can't trust it.

    I'd like to try one of these Walnut Daps, but as mentioned they appear to be in short supply.  There is a company called Rose Electric on Aliexpress for about $33 usd delivered which seems the cheapest right now.  Is Rose reliable?  Anyone know when stocks will be replenished?

    That's not the point - as a directly driven amp the walnut simply sounds different, it's not just coloring but more massive spectral change - depending on what you connect. If you put a different amp in the output chain you will not see the same effect. So it's useless for a comparison how well the walnut works together with a given IEM/headphone.
