@tee_dee Look at the tech in Mola Mola tamabqui (though old now, still unique). PS Audio, Playback Designs, and Chord with their FPGA approach, which I think is something that potentially can last for a very long time. This is new DAC technology. My next DAC will be an FPGA.
A 10 year-old DAC may not even have a USB input and if it did it is likely really bad, say unlike the USB on the modern Musetec 005 DAC.
