I have been checking prices of used Paradigm speakers recently and looks like the prices have declined sharply. Studio 60 v3 or v4 are in the range of $700-850 while Studio 20 are within $400 to $500 in ebay and Audiogon. Is this normal for used speakers at this stage of life cycle or Paradigm is no longer as sought after as they used to in the past? For the record, I sold my Studio v4 recently at $850 locally in NJ and eagerly waiting for Ascend Sierra Tower. Any thoughts?
