I have, well will have again, a Denon AVR-3300. As you may have read, mine is not working properly, but have been told I will get a new one. Anyway, I will quote what the owners manual says, and then ask my question.

"For Future Multi-Channel audio format(s), the AVR-3300 is provided with 7.1 channel (seven main channels, plus one low frequency effects channel) inputs, along with a full set of 7.1 channel pre-amp outputs, controlled by the 8 channel master volume control. This assures future upgrade possibilities for any future multi-channel sound formats."

This leads to my question. Does anyone know of or had these upgrades done? Does this mean with this reciever, I could possibly have it sent to Denon for an upgrade to make this 6.1 or 7.1? I know it is 5.1 capable now.
Thanks, Oak
