rodm_2001 - Congrats on the new arrivals! Unless your drivers are used, expect the speakers to change substantially as they break in. I don’t think mine were fully broken in until at least 6 months after I set them up.
As for positioning, the uneven triangle works for me, with the distance to the listening position being a little greater than the distance between the speakers. I have them ~2 feet from the side walls and ~3 feet from the wall behind them. I have a lot room, ~ 11 feet, behind my listening chair.
And while the Ohm Walsh x000 may not be the most hyper-detailed speaker I’ve heard, they are one of the most detailed sounding speakers I’ve heard that did not induce listener fatigue, at any price. So, the question is, do you want all the tiny details shoved in your face in a way that makes listening unpleasant for anything but a brief listen, or do you want to hear the bulk of all the details in a way that encourages long, enjoyable listening sessions?
And don’t ignore the cables! I just upgraded the ICs connecting my DAC to my pre, and it’s like I upgraded my speakers! Huge improvement, and I am digging my 2000s now more than I have in all the eight years I’ve had them.
