Just built this week. This was made from a brand new DL 103.This was a special project. The body is made of ebony and the adhered top plate is 3mm of carbon fiber. I've played this for 30 minutes to ensure that it is functioning correctly. I've built these before and really love the sound it produces.
The ebony body has been worked to eliminate resonance. All corners have been filed or sanded and then the body has been paste waxed and buffed. The custom carbon fiber top plate adds to the elimination of unwanted resonance peeks.
A lot of work goes into these builds to make something special that will challenge $1,200-2,000 cartridges.
