For sale is a pair of the well known and proven 3 Post stands from Sound Anchor. These have a top plate dimension of 12" wide x 14" deep and a height of 20". These will come with spikes that screw into the base for further height adjustment and isolation from the floor. These are in fantastic condition and rated an 8 conservatively.
As you know these are pretty heavy and if shipped will be in individual boxes and paid for buy the purchaser. I would prefer a local Southern California sale if possible but will certainly ship if necessary worldwide at the buyers expense. Payment via paypal requires a 3% US and 4% International additional fee to be paid by buyer as well. Audiogon seems to be having some issues so please leave me a number and email address to contact you directly for a better response to questions etc.
