About this deal
One of the most interesting things about this device is its multifunction: it can be connected to the PC at the same time, via USB, as a DAC and connected to the Smartphone, via Bluetooth.
Vrms power output respectively, meaning it is powerful enough to drive just about any IEM on the balanced port, the same as the BTR5 and UP4. As a result, the controls are very comprehensive and warrant a 8/10 rating, the only real downside again being the plastic build, which include the buttons, as a result the controls are not as tactile as the ones on the BTR5.Bluetooth:Generally pretty stable, though it is more stable over aptX than LDAC for me over longer distances.
Other than that- 2 years or so in and still trucking and I bought a second one for a different set up too. And the maturity of the APP makes it very easy to have absolute control of the device, and also provides a lot of information: help, links to manuals, to the forum, technical support, warranty management. The Qudelix 5K might not be the most beautiful looking or premium made Bluetooth DAC/amp in the market but it stands out not only for the good sound quality but foremost for its most innovative software implementation.All of the functionality has been really thoughfully considered to cover almost every use case and the team behind the 5K seem to release firmware updates every few weeks with each one bringing even more useful features to the unit.
