Welcome to our forum, Chris. I'm pro-Pioneer, too, but I certainly have had the opportunity to listen to more than just Pioneer. I'm glad you started this thread as I have been wanting to know more about your experiences. I have a number of pairs of vintage Pioneer speakers, not as many as you, and I have always wanted to hear about anyone who has demoed a pair of HPM-200s. I realize there is a technical and historical connection between JBL series and Pioneer series speakers of that generation - JBL L100 and HPM-100, for instance. But, have you heard or know of anyone who has auditioned the rarer HPM-200 speakers? I have heard the JBL L300s and liked what I heard. I regret not buying those, but I thought I would hang onto the notion I could eventually own a pair of HPM-200s.
Nando.
