Acuhorn R2R XD the board doubled for DAC in the fully balanced configuration. A device with an outstanding power supply, separate for each unit. The Superfast and low noise Vicor modules DC-DC converters. The device is enriched with Amanero DSD converter for a real listening session with the 1-bit music stream. I invite here the best source of Hi-Res sound high quality.
