For the first time since I have owned the 990, ( purchased 1/30/07 ) I tried to connect my headphones to the 990's headhone jack. The 990 is not recognizing the connection, music is still being channeled to the speakers.
Whats up ?

The only reason I plugged my headphones in was to see if my Sennheisser hd 280 pro's sound better than they do connected to my computer. I would love a set of headphones that sound somewhat like my Monitor Audio GR-20's speakers. Thinking I might get better sound from my 990 and, expouse some weaknessin in my computers ability to deliever is my quest for now. I plan on upgeradding my headphones, but it may also be a issue with my computer.
I am budgeted , I need to know how much upgradding I need, and if it will be enough for my computter to deliever.
