Description

It is equipped with an ultra-high precision, ultra-low jitter master clock, complemented by a specially designed clock isolation mechanism, ensuring natural and balanced sound reproduction. The analog section is composed of high-performance discrete components, forming a pure Class A circuit. The DA-1B is equipped with independent isolation circuits for each input port, preventing ground noise from mixing into the input signal. This design not only enhances audio quality but also enables stable support for DSD512 format and 768KHz PCM.

DA-1B employs a separate power supply, pioneering the use of a switching power supply to achieve AC-DC conversion. It can operate within a wide voltage range of 80-280V, , completely resolving the power supply challenge that audiophiles find most difficult to address.
