This is a Monaco Special Edition Isolation System stand complete with an upgraded carbon fiber shelf and Apex footers including both chrome and silicone nitride coupling balls. The carbon fiber component shelf measures 20.75" wide x 17.75" deep. This stand was used to hold a DartZeel NHB 108 amplifier with great effect. Complete unit is in excellent condition. The shelf has some small circular markings from the amp's rubber footers, but these can only be seen under high light with close inspection and obviously will be covered by the next component. Please see Grand Prix's web site for further information. Not interested in trades, but I am happy to address any questions from interested buyers. Please send inquiries to email@example.com.
