    Far too technical for my feeble mind but for $35 I'm willing to hear the difference, I realize many can't go without a screen to pick and choose as they go but most the time I just hit shuffle all and let'er rip:grin: I mean if I've put the file on the player I like the music and just let my DAP's be my DJ's for the session:rolling_eyes: Looking forward to whatever sound my $35 has gotten me:wink:

    Hello friends. I need help.

    The NE5532 operational amplifier with which other is compatible?
    I want to change the sound of my walkman.
    I would like to receive your recommendations.
    I have the DIY Walnut V2S

    Thanks

    Hello.
    Sorry.
    To put the 2xad825 you had to build a circuit or these are sold already manufactured.

    Thanks

    They need an adapter

    Ok
    I really do not know much about circuits.
    I'll have to study a little about this.

    Thanks

    I am not sure, I can not tell by picture
    Without the adapter they cost around 7 dollars each, that's $14 plus cost of adapter and from a good dealer it may cost a bit extra so I would expect it to cost about $20 or a bit more, check dealer feed back and when you buy from eBay remember if it seems to good of a price then it probably is a fake

    Here's a link to the BrownDog 020302 adapters that I buy (to install op-amps myself), and they also have an option to order it with a pair of AD825 op-amps installed, for US$19.50.
    They will also install low profile, shoulder-less pins on the adapter, if you contact them and ask.

    My Walnut F2 arrived in the mail on Saturday.
    The first thing I tried, was connecting it as an Amp, with a FiiO Taishan D03K (24-Bit / 192-KHz, Cirrus 4344) DAC for input, and with LZ A4 earphones (Green Nozzle, Red Back) connected to the Balanced Output.
    Watching some BBC documentaries, streamed from Amazon Prime Video to my Roku 4, my initial impressions are that the F2 sounds good.
    However, when I switched to listening to music, it was rather "thin" sounding - lots of Midrange & Treble, but not much Bass.
    So, I opened the F2, and replaced the OPA2604AP with a pair of LME49710HA op-amps on a DIP-8 header.
    Ah, there's the Bass. :ksc75smile:
    I've also used the F2 as a USB Sound Card (it operates at 16-Bit / 48-KHz) for my PC, and as a DAP (playing WAV files of my CDs) - and it sounds good with the LME49710HA op-amps.

    I took out the 825 and put in the AD8066. It sounds better but there are more high peaks then the 825 with the KZ ZS7. I will try to burn in both opamps.
