I have a Farad power supply being delivered from the Netherlands tomorrow for my Chord Dave DAC. Thier prices include shipping but they aren't cheap.
Dave uses 3 voltages so I had to buy 3 power supplies plus a custom harness than Farad makes.
They have what you need for Chord Qutest on the shelf.
I haven't heard it yet but if you give me a couple of days I'll post my impressions.
