The little Lepai amp arrived today. It's a solid little box and it does the job admirably, filling my unfinished basement with clear tunes. I set it up with my M22 on-walls and Onkyo 6-cd changer. I only temporarily set up the M22s. I'll play with their placement a bit and then I'll need to figure out the best way of attaching them to the cinder block... I'll probably use masonry nails to put up some speaker-sized pieces of plywood, then screw the brackets into those.
"I wish I had documented more…" said nobody on their death bed, ever.
