    MOT/ Diyer/Psuedo-pro/Pro/issues

    In light of recent events including some MOT's and N_Maher and Dr. Gilmore's findings with regards to some Singlepower amps as well as the massive uproar and mob-like mentality on head-fi, its becoming clear that there needs to be some form of regulation (well maybe not regulation) but something...

    Modding my way to the perfect Grados

    I've been a long grado fan... for well since I started head-fi and getting into music. I know that a lot of folks don't like grado for a lot of various reasons, but I've always felt that there is truly something amazing about the openness of their headphones. Its just so uncany that no other...

    Working on the gs1000 (*****56K Warning****)

    Hey folks, I tried looking for a fresh pair of SA5000 pads on the web and I sent a few emails to sony, but I haven't gotten anywhere. I was hoping someone who owns a pair knows where I can get a hold of some fresh pads otherwise I'd have to make them myself. Thanks, Paul

Before I go down that route, I'd appreciate any inputs, especially if anyone...

    IPhone LOD

    I'm curious if any DIYer or MOT have tried making iphone LOD's with some form of noise canceling like copper braid around the wires etc..

    KSC75 resistor?

    So I just finished recabling my KSC75's and I decided to add a resistor in line (approx 75ohms). I just measured the resistance and its about 132ohms/channel. First impressions... well they seem pretty good, and I have to say I might just end up preferring these to my SR80's. They just seem more...
