FWIW here is Fremer's review...not good... be sure to look at comments for link to manufacture response...
IMHO if Fremer didn't like them then the Briscasti are probably fantastic...Fremer is probably the #1 reason that I stopped buying Stereophile several decades ago...I think he was the one that gave fantastic review of the sonic improvement provided by Mpingo wood pucks.
