So no pics just yet. I need to get a couple more built. I hooked the test box up in the main living room. almost wore myself out getting to the sweet spot to the speaker and the others as I swapped them out. lol Her is my initial impression though. I picked cd's I am very familiar with. Allison Krauss, Norah Jones, Kenny Chesney. These seem much more detailed than what I am used to. They really do sound great. Piano, voices, cymbals sound so crisp and detailed. They don't do as well with bass at all. I am not sure what the switch does technically, but I can say I prefer the music setting. When I get the others done I will run them as main for a few days and tune them with the receiver and report back. My Boston CR85's are a lot warmer but lack the detail the 8330 guts do. I think someone could use them as the top part of their mains with some capable bass bins to fill out the bottom side of things.
