The GS-1 and GS-X will continue solely because I still have plenty of parts that I've invested in. If I were about to sell out of them like with the Gilmore Lite, then they'd likely be discontinued until I thought spending the time bringing them back or redesigning them was more worth it than working on a portable amp or DAC. Right now I'm working on getting all of the GS-1 and GS-X boards I have professionally soldered and the supply of them is somewhere between a few months and a couple years, depending on what demand is when they go "In Stock".
