i am not aware of any upgrade possibilities on my HK 525. Are you telling me there are upgrades or are you inquiring as to whether or not there are upgrades.
I dont think there are upgrades. There are no inputs (firewire) for software upgrades and i dont think they offer hardware updates

ya i know LOTR has some good Surround sound effects, but a lot of movies do not. i bought aliens quadrilogy and except for Aliens, the surround sounds were minimal. Alien. Alien 3 and Ressurection. Eh. Oh well
