    Fake OMX980?

    Came across this listing today and much to my surprise the seller claimed that his phones are genuine and he got them straight from Sennheiser. Not that I don't want to believe him but 100gbp off is a bit crazy, not to mention he accepts offers. Since I haven't found any information regarding...

    Does this mean my hiface gone?

    Last night everything worked fine, but this morning it struck me there's no sound playing from my fones at all. The B22 is still intact, and I doubt the likelihood something happened to my dac. I even tried switching to another OS yet things didnt get any better. I tried measuring output...

    Iqube V3 info

    So, the beast has been released for quite awhile yet I found nothing regarding impression/comparison here, let alone a review (moon said they are working on a review but who knows how long it's gonna take).   Anyways, anyone actually heard the unit? I love my v2 to death and the v3 looks...

    IEM crossover

    Don't know if this's the right place to ask, but well, I don't know anywhere else to go, diyaudio is too somewhere-above for me... Anyways, I've looked at several iem's internal while opening their shells and in most cases they only consist of some resistors with filter caps. So my question is...

    Broken AD2000 coil fix

    During my midnight listen I discovered the left driver went on and off as I twiched the cable, and few minutes later it went completely dead. Scared as I was (they are my friend's phones), the diy spirit within was awaken and after 4 hours with sweat and tears, the AD2000 were revived. I learned...

    UM3X gutted!

    So my um3x's cable is pretty worn thus I opened up the shell minutes ago. Quite surprising the crossover is nothing but filter caps! Here's a photo of the moment of truth =D   I'm wondering if we can use anything fancy here? Cap rolling anyone? XD

    Is it right to test headphone system using speaker's method?

    So yesterday one of my friend (a speaker audiophile) sent me a song he often used for testing speaker. After hearing it through my set up (k1000, b22, buffalo 24, hiface) which I'm quite confident that it's somewhere near the reference field and describing what I heard for my friend, he said the...

    How to calculate value for Rk for DAC's tube output stage

    So far there's been no reply in the main thread in diyaudio so I bring the question over here. Hope someone can enlighten this for me. http://www.diyaudio.com/forums/group-buys/156149-tube-i-zator-professional-pcb.html In short I'm sourcing parts and I'm not sure which value for the Rk I...

    Strange distortion

    I don't know if this is common among pc based audiophiles, but I'm currently experiencing some very strange distortion, which I used to think that it was mainly due to the inability of the system to produce that frequency well enough. Yet with my current rig: foobar -> asio -> hiface -> buffalo...

    Hiface click/pop problem

    I know this issue is so old already, but I cannot find any way round it yet. It clicks nearly all the time, during the track, at the beginning of each track, and surprisingly, the left ear clicks more than the right!  I tried all other codecs, and the DS clicks the most compared to KS or ASIO...

    Looking for headfi-er's in Coventry UK

I'm 19, 2nd year Maths and Statistics, young at heart, easy going and stuff. We can talk about audio things, and other things...

    diymod questions regarding capacitors

    After reading through the massive thread about diymod, I'm thinking about pulling the trigger in the near future but the questions of which cap to choose is still unsolved. My best choice now would be the Mcap Supreme 800vdc 6.8uF which runs about 25 pounds each. Though a friend told me to go...

    Is this clipping?

    I have my M3 fed by the udac, and whenever I crank up the udac's volume pass 6 o'clock, popping and buzzing appear where the cans get loud. If I turn down udac's pot and pump up the M3 to get the same loudness level those blemishes are gone. This happened to all of my phones At first I guess...

    Apple Airport Express -> i2s/coax -> Buffalo 24 or USB -> i2s -> Buffalo 24 or both?

    I just had this thought after having a flick through pages about the AX Now I have gathered all the modules needed for a B24, what I need is just a usb -> i2s module and I'm waiting for a solution from diyaudio. Some people suggest I mod the musiland but I prefer the other dedicated board...

    K702 left ear's problem

    Just woke up this morning to find out that my k702's left ear sound much quieter than its right ear. The problem doesnt lie in my source since I swapped them with the other phones and the they sounded fine. The cable is still good as I checked the 3 pins with my multimeter. Seems like something...

    Recabling (completely) yuin pk1?

    Hi guys, I have a small problem here that I need your suggestions. My pk1's left ear's cable was damaged while it got stuck under the door and I forgot to pick them up while walking, so the plastic sleeving (or cover) of the cable was torn, revealing the color ones inside. It's still fully...
