I ended up surrendering the speakers to the repair shop. Four or five drivers needed repair, and I don't know how much more life I could have expected from the remaining cones and surrounds, voice coils, etc... etc... I ended up going Tekton, Moabs. They fit the bill, satisfying my need for an adventurous leap into the unknown and supplying me with a commanding and subtle full range event. Currently, I'm testing out options for amplification.
The schiit aegir came in three days ago and the evident textures are palpable, rich, present. I auditioned a class D amp for a month and instrument textures sometimes lacked life, appeared hollow, or emerged in odd shapes. Voices were often constricted. I was caught thinking the amp was somehow revealing the space in which people sang, but then it seemed more likely that the voices never properly took form, and there was a kind of pinched effect around vocals. The bass was big, so that was attractive, but something as simple as a hand clap seemed inauthentic. I've also realized that my first impressions of a piece of equipment often have me excited about "differences" that may turn out to be evidence of weakness later in an audition, so we will see how things go with the aegir.
I wish it had more power, but then I would probably abuse that power and my ears. I don't really need to be listening over 90db, but I'm confused that the aegir, which would appear to work with my speakers, to push them to something on order of 107db, according to SPL calculators, seem a little out of breath around mid nineties... As I said, this might be a good thing... I don't feel my ears growing younger...
