"Gd." or "gd." is accepted abreviation for " Ground ". A ground plane is an area of coppere plating on a pcb, top or bottom, that is connected to gd. and provides shielding, to some extent, from RFI when used on top of the pcb and also makes it convenient to connect components to ground. A Gd. plane can improve sonics when properly laid out as it has lower resistance than the often used ground busses which often meander quite a bit before connecting to the Central Ground Point, or CG. Maintaining the lowest possible resistance/impedance on the gd. system, often referred to as "quiet grounds" results in greater resolution of fine detail. Try this with your CD player : use a DVM to locate all of the IC pins and other components that are grounded i.e. the crystal, etc. Then scratch off the conformal coating on top of the pcb at those points and solder a jumper directly from the pin to the top GP. I think you'll be surprised at the improvement of overall sonics.Happy Grounding !
