Aloha again. Would anybody know of a way to eliminate the hum I get when connecting a coax cable from my computer for digital audio to the 990. The sound is otherwise good and the ability to stream internet radio is awesome. I get the hum/buzz even with the power cable to the computer disconnected. ONly when I disconnect the coax cabe to I get the hum. (BTW, the coax is brand new straight from Blue Jeans...). Mahalo.
