Yeah, we really need to set up a page where the status of R&D is updated....
Meanwhile, here is what I know about those specific projects:
1) the active crossover is temporarily on hold while we re-evaluate the technical approach. So far we've been using "Sallen & Key" filters based on improved cathode followers (C4S loads and shunt regulated), but we want to try low-impedance LC filters driven by a power buffer, and see if there is a significant difference in sonic quality. The buffer would of course have other applications ...
2) the DAC is still in work, not sure how long the development time line will be but there's lots yet to try out.
3) the Stereomour is still awaiting a resolution to the output transformer supply problem. Once that is resolved, it should go together pretty quickly.
