I use the -10dB track. I'm not into the bass heavy "music" that many here seem to like. I primarily listen to classic rock, blues and jazz. The problem I've run into is that many older recordings (like from the 70's) aren't recorded at a very high level. Using the -10dB track helps to bring up those songs to acceptable levels when I want to crank them up a little. On more recent recordings the same max volume settings for older recordings tends to be TOO loud and I can hear it just begin to stress the speakers and subs. On these tracks I tend to back off the volume a bit. One of my fave recording is Robin Trower's "Bridge of Sighs". On my Advent OGM1 my max volume setting is 53 of 60. With my current gain settings a volume of 53 is plenty loud for my liking. If I leave the volume setting the same and play a newer track (Mayor Hawthorne's "The Walk" for instance) at that same max volume setting I can hear that the speakers are getting close to their limits. I can always turn the newer, louder recordings down a little since turning the older recordings up even higher isn't an option.
