Acquired one of these a few weeks ago and it sure is not pretty as my PL 2000II but really woke the range of my Nikko Alpha II and the JBL 150's. Seems to have a twitchy relay that takes 15 to 30 second to kick in fully on the left channel but I always let my amp warm up a bit anyway before applying the tunes to it. The adjustable loudness feature works well in my situation and the clarity is great. Like the rest of my stuff one day it will be updated and playing the WOPL's after they get done. Hopefully I'll live long enough to get there...
