Audiophile DAC & DSD Converter with Class-A Super Tube Stage

The Acuhorn R2R TS is a compact device with a beauty image of music thanks to the tube output stage. Applied subminiature power triode by Sylvania with the same parameters as big 300B vacuum tubes. Powered by digital to analog converter loaded FPGA Spartan 6 discrete R2R ladder. Compatible with all types of music file formats. Working together with audio device by USB audio or SPDIF. And state of the art power supply by Vicor modules.

features
R2R ladder 28 bit resolution 384Khz dac by Soekris. Loaded FPGA Spartan 6 technology oversampling up to 3.072Mhz. Frequency range +0.1dB -1.0dB 20hz - 20Khz. Total harmonic distortion + noise <0.008%. Clock jitter RMS 0.8 pS typical. Resistors precision 28 bit 0.02% resistors. Signal to noise ratio 20 Khz bandwith 129 dB unweighted. Input SPDIF up to 24 bit 192 Khz. Input I2S PCM up to 24 bit 384 Khz. Input I2S DSD up to DoP128 and DSD256.

Autoselect between the USB audio device and SPDIF inputs with priority SPDIF. Manual switch of input selection SPDIF coax or optic. RCA single ended tube output: 2.8V RMS Zout 1200 ohm.
