    It will only make it worse. In Walnut the "adapter" of 100 Ohm is already built in :D It is possible to reduce the output resistance by soldering in parallel R7/R8 other resistors. 100 Ohms in parallel will give a total resistance of 50 Ohms. 10 in the parallel ~ 9 Ohms. This increases the volume, improves bass accuracy, but can increase background noise too.

    hi ozkan,
    re0 with walnut definetely a very good combo, the first thing i realized is more bodied sound on re0 i didn't notice before.
    walnut adds some warmth but within a margin; it depends on what opamp installed.
    i listened it with lm4562 which is fairly neutral opamp, added some warmth but not much as i expected.. with opa2134, it should be more sweet/warm sounding combo, i will try this in a few days..
    also, please consider this is a modded walnut; 1000 uF pw supply cap changed to panasonic nhg bypassed with wima 0.1 uF cap and potentiemeter replaced by alps rk097 series..
    hope this helps.. also please feel free to ask for any further questions.

    Can I ask you a general question about capacitors? What effect does changing the caps produce and which are the best ones regardless of price? I have another project I'm pondering but would also like to know a little insight as I've got a Walnut coming my way soon too.

    For anyone who doesn't like to tinker and make things better, like changing the Original Walnut v2.0 in some way to make it nicer to yourself (opamp, case, etc), don't buy one, if you don't tinker. The Colorfly C3 is a better music player in my opinion.

    I own both, the c3 amped is killer.  Without an amp the bass sounds rolled off and thin in my opinion.

    what headphone

    i'm not an expert to explain it technically nor i have deep experiments about caps.
    also it's waste of time and money for me trying to find best cap or ay other component..
    i prefer listening music to listening components' sound..  
    nevertheless, i try to use decent or good caps and replace if there is one below average.
    what i know about best cap is;
    there is no best cap but there are suitable caps for the application and taste like every other audio component..
    you can find some valuable info on caps here:

    You can look at my profile, but lately KSC 75 on headband, Edifer H180, and Grado 85e.

    I assume Walnut doesn't have a good synergy with BA iems like PFE012? I just ordered the latest version of Walnut V2 with data port and wonder if I did the right thing. Any opinions will be much appreciated.

    Thank you endia for your impressions. Glad to hear that they sound better and warmer even with the moded Walnut. :wink:

    It depends, with the Burson v5i the multi-BA MusicMaker Shockwave III work surprisingly well.

    Is there a list of the good opamp's with the Walnut v2 starting with stats and price? Thanks.
    Are the opamp's that are more expensive than the v2, really worth it?
  14. Dark Helmet
    The ones that have worked best for me are:
    Phillips NE5532AN Made In Thailand stamped on it - Great in a stock Walnut, probably my favorite with the OPA 2604
    Bur Brown OPA2604 - Currently in my all Silmic modded Walnut
    Signetics NE5532N
    Bur Brown OPA2134
    AD825 - This has noise on my modded and stock Walnuts
    Burson V5i - Sounds good, expensive, about the same price as a Walnut the previous 5 are cheaper, under $6.  With the stock Walnut there was a little hum from the opamp on all three of my Walnuts
  15. LaughMoreDaily
    I know where to buy the Burson (Googled),
    But where did you get the more affordable opamps? E-Bay? Thanks. :)
