This price is for two sets of these standalone isolation feet from Grand Prix (three 'feet' per set) Selling my entire system, so these must go. These are really quite incredible. I was a doubter, but couldn't un-hear what they did. Under my Lumin, they provided smoother, more natural inner detail and shading. Under my ARC Ref 3 pre-amp, they solidified the soundstage and provided better focus and attack. Under my ARC Ref 75, the redefined the lower octaves, like I changed from KT120s to KT150s tubes. Perfect condition, all original. 9 only because they are used. I bought them from Esoteric Audio for 1100 a set about 18 mos. ago. I will consider breaking up the pair.
