Map, (sorry all if this wanders a bit off thread).
I'd need to hear larger Ohms to answer the question. I talked to John about possibly switching to the Sat 5 for use with my subs, but even if I go that route, its gonna be a bit off in the future. Until that happens, 100s are the only Ohms I know. Very fine and - in some ways - I prefer them to any MBLs, but not for that quality of imaging/dynamics Dylanhenry dubbed "hyperrealism".
As to room matching, I would expect the MBL 101s to overwhelm my medium sized room with info below 150hz or so. I have always felt that the bass from this speaker is a bit "ripe", even in the 2 VERY large rooms I've heard them in. For this reason, I thought the little MBL 121 and a good sub might be a better choice, but I was a bit disappointed when I heard them. The same applies to the smaller MBL floorstanders (111 and 116, I believe) - they provide just a taste of the 101, but not the whole enchilada. So, its tough to speculate about bigger Ohms without a listen. One day (pretty) soon I may have a better basis for this comparison...
