Thanks for the well thought suggestions. I had this pair in my system orignally and replaced them with Sonus Faber Cremona. I friend has a pair of Dunlavy SC-IV and these PSB's just waxed them in a one-on-one test in my system and his. As a project, I thought I'd see if I could make them sound even better, albiet different, I realize.
I bought the PSB's used sometime ago on Audiogon and they were purported to have only three months usage at that time. In keeping with advise to document all original wiring, I removed first the post covers, notebook and pencil in hand. I found that the "original" internal wiring includes Monster cable that has been soldered directly to the posts and crossover connections. Hmmmmm. Looks like I won't have an accounting of the "original" wiring, but one of a previous "rewire"! Guess I will have to contact PSB to find out what "original" really was.
