In many ways, the JC-1 and the HCA-3500 are almost identical. They have the same circuit topology, use many of the same parts in the same places. The JC-1 has a larger power supply per channel, better layout, and an extra output transistor pair for each output stage, in order to support higher sustained output currents.
However, they don't sound the same, especially in stock form. For a few years, we extensively modified the HCA-3500 and made a better sounding amplifier. Our problem was that we also became responsible for any warranty obligations on the unit. This made it unproductive for us to continue with it.
The JC-1 was our chance to put into the design what we had learned from modifying the HCA-3500, and to give it a better circuit layout.
