KAP,

I purchased my 990 back in early 2005. I upgraded the firmware when the original update came out, but did not upgrade to fix the "sub trim bug", as I do not have my 990 setup in a mode that should be affected by this. The one firmware update that I did do was easy. But as pointed out previously, please download and read the directions thoroughly before proceeding and refer to them throughout the upgrade process.

Good luck and enjoy your new sound.

Jeff
