Musical Fidelity M1 DAC (£399)

摘要

Musical Fidelity has updated its M1 DAC since we tested it[HFN, OcflO]. What has changed is its USB input specification: in the original M1 this was limited to 16-bit/48kHz, whereas this latest variant now offers 24-bit/96kHz capability. This remains 'USB Audio Class 1.0' of course, consequently no proprietary drivers need to be installed. Our Lab Report shows broadly identical technical performance, as the M1 still employs the same 24-bit dual-differential DACs with oversampling to 192kHz, an LED on the front panel proclaiming '192kHz upsampling' once the M1 has locked on to an incoming signal. Much is made by the company of its attention to detail in the design of a power supply that includes choke filtration on the mains input.
