PS AUDIO DirectStream DAC MKI Black Trade-In
- No Bridge
- Edcor Transformer & VOCM Mods
DirectStream converts every input signal, both PCM and DSD, to single-bit, high sample rate 20X DSD signal. Use of a FPGA rather than an off the shelf DAC chip provides immense processing power, resulting in complete lack of digital glare, and allows the owner to download OS updates as they are released.
