This thread is to discuss the exceptional non-oversampling (NOS) R-2R (resistor ladder network) digital-to-analog converters (DAC) created by MHDT Laboratory Audio Devices.
http://dhost.info/mhdtlab/
There are a few threads dedicated to specific DACs from this company, but I feel we would benefit as a community if we combined our discussion of their various offerings into a single thread. The idea is to offload the general discussion that goes on in the Havana thread and keep things current with a regular Head-Fi member who can update the original post.
I would like to keep this post up to date with information and guidelines on MHDT's current and past lineup.
I will also attach current user manuals and drivers if the forum software lets me. Otherwise, I'll provide a link to them.
