No setup yet. What I would like to end up with is two 4-channel amps based on the four Marchand boards. I see these boards as a very cheap and easy way to build a set of high quality multi-channel amps that I can use to experiment with various set ups. Bridging, paralleling, active XO, home theater, etc. The second project I'm working on is an all-chip integrated amp, based on a pair of "classic" GC and opamp-based preamp with tone control and separate opamp headphone amp. The theme of this project is "how good can an all chip system be without using "boutique" components.
