The board is great. However, my noise level is around S9 using a 64-bit Asus laptop with the board in a grounded minibox and the usb and audio cables run through a couple of toroids. The noise level on a Drake 2B sitting next to it is about S3. I have read that laptops tend to be noisy but the one you were using at Shelby seemed fine. Any suggestions?
Thanks,
