Just noticed this on the Denon UK site:
Software upgrade for AVR-3310
Adds Audyssey DSX to AVR-3310
Audyssey DSX sound processing technology extends 5.1- and 7.1-channel sound sources to a wider and higher dimension considering the human perception that is usually focussed on the front. A more spacious sound is achieved through a pair of wide speakers placed wider than the usual front speakers, and a greater sense of height in sound is achieved by adding two height speakers above the front.
Until now, Audyssey DSX was only available with Denon's upper class AVR-4310 and AVR-4810. With this new feature upgrade, current and future owners of the AVR-3310 get the chance to add a unique technology to their home theatre. In the future, Denon will continue to sell the AVR-3310 without Audyssey DSX to give their customers the right to choose whether they would like to have this feature or not.
During 2009, several thousand owners of an AVR-4308, AVR-3808, AVC- or AVP-A1HD succesfully used a similar opportunity to upgrade their devices with new features at a fair price point thus further increasing the value of their Denon product.
