I have just received a new GS-4 with DCC on-board without sound. It will be operated on a straight DC layout. Is there an aftermarket distributor that has a plug in sound unit that would work. I have tried MRC sound units for DCC ready locos with unsatisfactory results. They drew too much amperage resulting in insufficient power available for the motor.
What power pack were you using?

I have both a MRC 2400 and a MRC 2500. Plenty of power and amperage available. The MRC sound unit cuts the loco down to where it barely makes it up grade with its consist. Without the MRC sound unit it requires about 75% throttle to make the grade.
The new 1800 series decoders seem quite good.

Their are not any DC pnly sound systems that are really good. However almost all DCC sound systems work on DC. If you want a plug in installition then you should probaly go with Loksound decoders. These produce verry good sound but are a little spendy.
