Upgrade your source. I've gone from the Denon DVD-5900, to Oppo, to the Toshiba HD-XA2. The Toshiba is in ANOTHER league in regards to the upconverting ability of standard dvd's. The sound is better than the Denon also. Use the HDMI to your Mitsubishi Diamond DLP, and you should see an eye-popping, almost hi-def picture.
If you then want to spend more, go with power conditioning.
Be aware however, that the best power conditioning units cost plenty. (IMO)
