Thank you for the input. I wasn't sure if Jadis had a U.S. service center or not. That is certainly a strike against it. I'm leaning toward the Modwright for the reasons you cited. However, I'm not sure if it will be "tubey" enough for me. I listened to the Mac when I tried out my speakers and didn't care for it.
I had considered the Rogue but opted out due to a lot of posts which described it as more for rock and roll than detail and nuance.
