This is the first flagship D/A converter from Chord Electronics of the UK. The body is labeled DAC64, but it's a DAC64mk2, which has improved power circuits and an added power switch, and the BNC input has been expanded to two lines. I recall the price at the time of release was around 400,000 yen. The body is made of solid aluminum block, so it's quite heavy. I've been using it for about 10 years, but I'm selling it as part of a decluttering effort. It's an imported product, so a UK standard power plug was included, but it also supports 100V input, so I'll include a general-purpose power cable for domestic use. Two BNC to RCA adapter plugs are included as a bonus. I've also included a downloaded English manual and a printed ChatGPT translation. It seems that the lighting lamp won't turn on even if you switch it on unless there's a signal from the input terminal.
