Hi Mstark.
Pretty nice set-up. Do you still have Audio Nirvana Super Cast 15 Speaker in those Open Baffles? I had purchased someone else's OB set-up that had the AN 12" driver and the soundstage seemed a bit low to me. As if it was way below my ears. At the time though I had a modified Hafler DH-220 powering them along with a Pioneer Pre-Pro. Does the AN drivers just like tube amplification?
