Hi guys, just bought a 2600 and im having trouble understanding what the deal is with Dialnorm. Usually, DTS dvds are louder than DD and i turn them down a little..but on tested a lot dvds today it seems that the DTS are now much quieter and when i switch to DD it tells me Dialnorm +4db. Does this mean i have to turn it down or is the amp doing it? Listening to MUSE Hullabaloo dvd right now and the DTS is MUCH quieter and switching to DD gives the rears way more volume even if i turn the volume down. Any suggestions?
