We have had good experiences with boards designed by Andrea and Salas, and laid out/printed by Quanghao. The shunt PSUs, DAC and tube I/V threads have gone for over a year and got highest entry rates with massive orders, links to

I recently talked to Quanghao and knew that he's now focused in developing new products, like balanced circuitry for preamp, and very busy. Then I raised wonder on about the matured products which were best welcome by DIYers in the Forum. He said he may think about freeing those back to the non-commercial GB as the cost of design, critical testing and production set-up are amortized. Then members will enjoy lower bills.
For continuous proliferation of these great designs, I start this thread. If you all see this is of interest and good for, I'll talk further to Quanghao on the price, expectedly around 20-30% reduced.
Quanghao, Andrea and Salas, your comments are welcome here, as well.
