Accuphase DAC-60 Digital Input Board

Product Description

The Accuphase DAC-60 Digital Input Board is a high-performance digital-to-analog converter module designed to enhance Accuphase preamplifiers and integrated amplifiers with versatile digital connectivity. Featuring a 2MDS+ (Multiple Delta Sigma) converter with dual ES9016K2M (ESS Technologies) DACs in parallel, it delivers pristine, high-fidelity audio with exceptional clarity and dynamics. Supporting high-resolution PCM up to 384 kHz/32-bit and DSD up to 11.2896 MHz, the DAC-60 integrates seamlessly into compatible Accuphase units, offering USB, coaxial, and optical inputs. Its compact design and meticulous Japanese craftsmanship make it an ideal upgrade for audiophiles seeking reference-grade digital performance in their hi-fi systems.  

Key Features  

• 2MDS+ D/A Converter: Dual ES9016K2M DACs in parallel reduce noise and enhance linearity, delivering analog signals faithful to the original source.  
  
• High-Resolution Support: Handles PCM from 32 kHz to 384 kHz (32-bit) and DSD at 2.8224 MHz, 5.6448 MHz, and 11.2896 MHz (1-bit, ASIO only for 11.2896 MHz).  
  
• Versatile Connectivity: Includes USB (Type B, 2.0 High Speed), coaxial (75 ohms), and optical (JEITA standard) inputs for broad compatibility with digital sources.  
  
• Automatic Input Switching: Prioritizes coaxial, optical, then USB when multiple signals are detected, with seamless recognition of sampling frequency and bit depth.  
  
• Low Noise Design: Achieves ultra-low distortion and noise, ensuring transparent, expressive audio performance, as noted for its “vivid and powerful” sound compared to the DAC-50.  
  
• Asynchronous USB: Supports asynchronous data transfer for reduced jitter, improving sound quality over the DAC-50’s synchronous design.  
  
• Markerless DSD: Processes DSD without DoP markers for native, high-purity DSD playback.  
• Handcrafted in Japan: Meticulous construction with premium components ensures reliability and sonic excellence.

Why Choose the Accuphase DAC-60?

The DAC-60 transforms Accuphase preamplifiers and integrated amplifiers into high-resolution digital hubs, delivering audiophile-grade performance without additional components. Its 2MDS+ converter and asynchronous USB design reduce noise by 10% compared to the DAC-50, as noted in AudioAficionado.org discussions, offering a “more vivid and powerful” sound ideal for rock and jazz. Users praise its seamless integration and expressive dynamics, though some prefer the DAC-50’s “subtle and delicate” signature for certain genres. With support for high-resolution PCM and DSD, and compatibility with a wide range of Accuphase models, the DAC-60 is a future-proof upgrade for audiophiles seeking to enhance their system’s digital playback capabilities.
