Product Information

I waited patiently for a few weeks since my CIEMs were in the works. Time has passed, but nothing changed. The only thing I wish is easily accessible internal and replaceable, in the event that one component (battery etc) failed, one have the possibility to fix it. In everyday use, the first hurdle is memorizing the button press commands and which button does what. bands and very, very feature rich. It also has 20 different slots for custom EQ presets that you can make yourself. It even is compatible with AutoEQ presets which will apply seamlessly! Hi guys , I realize I'm quite happy with my s22 ultra + tidal + DAC + IEM / Low impedance headphones , so I want to buy a new DAC , something versatile I can use with BT or cable depending the convenience , I think the Qudelix have an amazing APP and I love the idea but the BTR5 seams a more reliable device , or I'm wrong ? Because all this features are funny for a while but at the end of the day you want something trouble free that doesn't let you down and stop working after a while , opinions ? Thanks in advance

Now the highlight of this dac is the PEQ come on i thought it was a gimmic. But after using it does make difference. So, once you configure the EQ using the app, you no longer need to launch the app to see if the EQ runs or not. The operating profile automatically switched to the performance mode upon the presence of any USB VBUS connection. UNBALANCED 4VRMS: To the 3.5mm output, 5k works with single ES9219 DAC/AMP. The ES9219 SABRE HiFi SoC delivers audiophile-grade sound quality and 2VRMS output power, allowing the ES9219 to drive the most demanding headsets and provide a real line-level output to match professional audio equipment.

Band PEQ/GEQ (64-bit double precision) The embedded pro-grade equalizer is a vital benefit of 5K DAC/AMP over other similar products. It processes every incoming audio from everywhere: Youtube, Apple Music,... What is more is that the 5K supports the open source AutoEq project which helps users to load and apply eq presets from the AutoEq project. Not much to expand more here - as stated at 1), it is absolutely excellent when paired with my Sony Xperia 1 II Can the 3.5 or 2.5 outputs be used as a line out into a receiver/amp? In other words, can these portable bluetooth amps effectively replace a desktop DAC like my Schiit Modi 3. Can't say anything about solid in the literal sense of the word. I have my Qudelix only since November 2022. However, on the software side of things some things have changed recently. And I do have an opinion on that.I also appreciate the light weight of the Qudelix, which is much less noticeable clipped to my shirt. The BTR5 really pulls down and is annoying. If you like to equalize your earphones and have full control of the DAC functionality then the Qudelix 5K is the one to have. With 4V RMS on tap from the balanced headphone output, the Qudelix 5K can run pretty much every earphone and a lot of sensitive headphones like the Sennheiser HD660S. The sound is crystal clear and transparent with great source fidelity and very good technicalities.

The Qualcomm QCC5124 Bluetooth chip is also nothing exotic at this price tier; however, Qudelix has put its little spin here. Instead of relying on squiggly PCB traces, the receiver uses a separate 3D antenna. It makes the 5K more immune to failing signal strength due to direction changes and increases connection reliability at a distance. Qudelix released a pair of wired IEMs called the QX-over. By having two ES9219C audio chips on board the 5K, Qudelix used the four separate audio outputs to create a digitally filtered active IEM system. Judging by the published impressions, while technically interesting, the QX-over didn’t really deliver sound-wise. Technical Specifications

For those unaware, the Qudelix 5K is the new Bluetooth DAC/amp from the former CTO of Radsone, and it features 2 Vrms SE output, 4 Vrms 2.5mm output, aptX Adaptive support, and up to 24/96 USB DAC support. I’ve hesitated since this was reviewed as I like the functionality but the measurements seemed poor in some areas. Owners bias withstanding, can anyone speak to how it sounds? Is it to be considered transparent to human ears? The Qudelix-5K is the world's 1st Bluetooth DAC/AMP to support all the latest codec technologies, including aptX Adaptive, LDAC, AAC, aptX HD, aptX, and SBC. The Qudelix mobile app displays the real-time active LDAC bitrate. Qudelix-5K is the only receiver that provides accurate bitrate information. The equalizer is effective and processes every incoming audio from everywhere: Youtube, Apple Music, Spotify, iOS, Android, PC, Bluetooth (all Codecs), and USB.
