The H101 is a DOA based on the Studer A101, developed by the guys at HLab Audio. I am offering a one-off PG-DOA to bring this discrete op-amp to your attention, and because I enjoy the experiment. Build time will be approximately 10 weeks, as I need to have a new PCB produced. The op-amps will be socketed, allowing you to swap them out and experiment with different flavours. Total price is 3360 euros, €500 deposit on order, 2860+shipping on delivery.
