Plixir BDC solving his noise problem

I am very happy with your Balanced DC Power Supply for my Laptop! It has solved my noise problem!

Previously, whenever I plug my D-SPEAKER ANTIMODE Dual Core into my PC USB input (to stream music from PC), there will be a humming high pitched noise coming out from my speakers. I have tried many methods, getting and IFI USB power supply, trying various grounding methods (plugging everything into 1 strip to prevent ground loop) and using other power outlets but just cannot solve the noise issue totally. After using your Balanced DC Power supply for my Laptop, the noise issue is totally solved! Now there is no more noise from the speakers whenever I stream music from my PC to the DSPEAKER. The sound quality is also much better than before!

Thanks!
