Qudelix

Switched to 5k after trying BTR-15. The software here is SO much better than the competition. I wish they could make the UI a little bit nicer and prettier but the sheer amount of options is what we’re here for. I wish FiiO and Qudelix could get together for a collab. FiiO makes the hardware and Qudelix the software. It would be amazing. Oh well! Thanks Qudelix. We’re all eagerly awaiting the 7K or whatever is next.

Probably one of the greatest purchases I have ever made. The companion app is amazing and extremely easy to use with tons of customisation. Although they have removed the ability to toggle absolute volume and volume protection in recent updates. Hope they’ll add it back but other than that its been working perfectly.

I'v been using this app with my qudelix 5k for over 4 months now. I'v used it multiple times daily and have never had an issue with it. I have tried using about 90% of the features and all of them work flawlessly. This app is a LOT better than the one used for FiiO BTR-5. Overall, Qudelix 5x is a quality DAC and this perfectly well made app completes the product 100%.
