Gustard A-18 owner reporting. Fantastic sound, excellent build quality, only niggle is the tiny fonts on the OLED display. Luckily, once set up, the display should be kept off anyways. Which filter are other people using and are you able to hear the difference at all?
FYI I've tried Topping D70, Dx7 Pro and D90 as well as Chord Qutest DACs. Currently listening to Oppo 105D, Pioneer N-50AE, Cambridge Audio CXN V2 and the A-18.
If you're in the market for a DAC - put Gustard A-18 on your shortlist.
How does the Gustard A-18 compare with the Cambridge Audio CXN, as this is my current setup. Do you notice a big upgrade in sound, or is it an incremental upgrade?
