I have been slowly working on this project behind the scenes, without posting about it much (aside from on ComputerAudiophile.com). This is a “discrete” delta-sigma digital to-analog converter (DAC) developed by Signalyst (although, this wasn’t made by them).

By the way, the BF-50 uses a 12A7 (Tungsol) electron tube for both rectification of the AC input and amplification. Both […]
