Guys and gals, I did all the things you suggest, turning the treble up, down, flat and the bass the same way. It's got a tipped up high frequency but no extended high frequency. Everything sounds sharp and it sounds brightly cool on pop, rock, etc. Their demo DVD-A used a multichannel mix of jazz with the classic guitar in back of you, keyboard back on the other side, bass in your head, etc. Sounded like my old pingpong stereo Command LP's of yesteryear, which admittedly, can be fun. Not realistic.
Sarah Brightman Webber EMI, Szell Philips 50th Beethoven 5/Sibelius 2, Van Cliburn Tchaikovsky pc 1 and Rachmaninoff pc 2 RCA hybrid, and others, no go.
I ended up with bass 1-2 up, treble 3 notches down and most of the sound away from the center (terrible speaker), with a bit more sound from the back than the front speakers and left right equal.
