I am impressed. Last night (this morning 12-1) I listened to a "Simply Red" concert on Voom sat. 5.1 Dolby and I feel like I heard every nuance. I even did some calibrating mid-set to see the effect of changes. The 60's, 150, 8's and 500 gave me a great concert. Right now I have the crossover at 100. Adjusted the 500 to 1/4 volume. Video of the footwork of the organist showed were the bass note were coming from. Still more tinkering to come. Love this system so far.
