When i couple my ipod video and my ibasso D3 with a Qables performance line LOD, the audio gets muffled, i lose the vocals and only hear certain parts of the music, however when im touching both the amp and ipod the audio returns to normal. Anything I can do?

Only after i bought an 0404USB did I notice that there is no mini input. And now I can't use a mic with counter strike. I did find an adapter Neutrik NA3MJ 3-pin XLR Male to 1/4" Female Stereo Locking Jack, Wired | Full Compass though, and I wanted to find out if this will work with a normal...
