Thanks for the encouragement, Al, Ray and Pierre. The deep geekery on gear has become a passion, and listening has taken me to some transcendent places.
Ray, I don't have any Fela. I've delved into the genre by way of Pandora. It was seeing Thomas Mapfumo at a local coffehouse that hooked me.
Lapierre, I've got a cheap 20a outlet on the dedicated line. Room for improvement? Tell me about your experience. I've heard some Yellowjackets, but they've seemed a little too smooth and polished for my tastes. Great musicians to be sure! Will revisit them upon your recommendation.
Next direction is already in the house: Zu Omen fullrangers. They're just reaching break-in now at around 300 hours, and it's been 2 steps forward, 1 step back so far in terms of placement. I've got great tone and dynamics now, but the imaging isn't there yet; the speakers have yet to disappear and allow for precise placement of instruments within the soundstage. Pictures to come!
