The left wall was almost completely covered with a heavy drape. On the right side wall was paneling with what appeared to be randomly spaced 24"W x 15"D shelves which were used to hold display models of the Marantz gear. The riser and the rest of the floor had a heavy shag carpet. The speaker lab/sound room had an 8"H x 3'D riser running completely across the 28' front of the room. Bart and Dawson had appropriated a large 28' x 35' x 8' room at the Marantz manufacturing facility in Sun Valley, CA where they were building the last U.S.-made Marantz-branded electronics. My education in entering audio at that time didn't end there. And that this 14 gauge Belden was the wire that Locanthi had specified to be used as a standard for all speaker development. I believe each conductor had around 50 stands.Īll I was told at the time I started in the lab/listening room was that famed audio pioneer Bart Locanthi had consulted with then Chief Marantz Engineer Dawson Hadley about setting up a speaker testing facility. "Stranded copper" was the only description. Back then the speaker cables we used in the lab/sound room were what I eventually took home and used in all my systems for the next twenty years.

My first thought about even needing a "reference" cable was when I started at Marantz designing speakers in 1971.

#LARGE ADVENT SPEAKER CLOTH UPGRADE#
After reading that series just about anyone who really cares about using the cable path as a legitimate upgrade had a fairly good handle as to which new cable might offer true sonic improvements versus a "snake oil special" which somehow filtered the audio signal.

Initially, the Audioholics topic that impressed most was their multi-part series on cables.
