Super Clif speakers

Does anyone have feedback on these speakers?

I have come across a used pair(year 2000). I have auditioned and they do sound very nice however I am not sure if $1400.00 is a fair asking price. Thank you for input.
the value in use equals the value in exchange. if you have auditioned a number of speakers in the price range $1200 to $1600 and you prefer the clef speaker to all others, then the value in use , i.e., what they are worth to you, may exceed $1400. only you can place a value on the speakers.
