Qudelix 5K Reference DAC AMP

Product Information

Qudelix has some power budget numbers for a few popular headphones on this page for a better idea of how much this small thing can handle. The cables are of typical quality with a plastic sheathing and they are relatively weighty and stiff. While the low-end is nothing elevated, when using the DK-3001 Pro and Dita Fidelity which are very neutral their bass they gain more body and little more solid impact and decay, and even the 3-BA Fibae 3 sounds less bass light.

It's true that the connected headphones have been low impedance IEMS or low or medium impedance earbuds. Yes it's more premium and with fancy OLED but without the case, good luck not breaking it due to slippery sandwich glass construction. When ON it will broadcast BLE packets with its public address, which is unique for each device and, therefore, traceable.

Overall, although maybe the not most premium feeling device, it is solid and I have little worries in its long-term durability, therefore it gets a 8/10.

balanced, so the numbers seem rather accurate, and anyway is the best battery time among other BT receivers.

The QCC512x's ultra-low power consumption and more powerful DSP capability allows application devices to maintain a more secure, high-bit-rate LDAC stream for longer. 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 multipoint is pretty good generally, but it will bug out and distort if both bluetooth-connected devices start playing audio. Love my Qudelix 5K, but hate to see that there is no app that can work without Chrome (or other Chromium based browsers). The maximum volume is 0dB, but when the high gain is set, the maximum is +6dB, which means doubling the amount of volume. The Qudelix 5K comes packed in an environmentally friendly cardboard box and includes a USB C to C and USB C to A cables of 120mm length each. When connected to my PC via USB C (I do recommend getting a magnetic plug for it, makes your life whole much easier) it immediately starts working as a main audio device.EDIT 2- life gets more complex if its the same device you are connecting to via USB and BT- but the setting input- bluetooth- auto disconnect for USB DAC might help.

Given my failed disassembly attempts, I am using Qudelix's own photo of the PCB employed with the 5K. I can understand if developing an extension for Firefox is too much work to be worth it, but making an Electron application based on the Chrome extension should be relatively easier. The key difference between them is in the embedded equalizer, the BTR5 has a simple 10-band one which is only effective in Bluetooth where the 5K has the best and most configurable equalizer which is also effective in USB mode. For the mobile and outdoor use cases, the standard profile provides the best power efficiency and good enough sound quality, by trading off 2~3dB degradation in sound performance.You can control the volume of the Smartphone, the device and display the Bluetooth codec being used, as well as its bitrate and transfer speed. Have it running dual connection and can use the BT from my TV (via optical TX unit) and my iPhone so can still use the app for EQ. The Q5k comes in a very simple cardboard box, which includes the BT device, USB-C to USB-C and a USB-C to USB-C cable, as well as some paperwork. I got the Fiio more than half a year ago, and although I was excited initially due to the reviews and design - I grew to almost hate it really quickly - and i've been through 2 of them already.
