Qudelix 5K Reference DAC AMP

Product Information

At the upper part of the chassis there are located the two headphone outputs and at the bottom the USB type-C port. I made my own setting of EQ for my KZ ZS6 IEM (which I'll replace soon, it's already 2/3 years old) and I love how accurate the frequencies change. There are always differences in their final tuning when compared to each other, but none of them put much coloration to the sound or go overboard sounding too warm or too bright. 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.

It should be noted, of course, that the 5K is the first LDAC receiver to display the active LDAC bit rate. The box and its design, through a single sheet of untreated cardboard, its drawings in black ink and its schematic explanations, give an idea of a different product, where the effort is inside and not in other less superfluous things. It is not that the wired connection isn't better than the Bluetooth but in most situations you will find yourself preferring the convenience of the wireless connectivity.Otherwise, the three feature the same dual ES9218P DACs, balanced and unbalanced ports and a USB-C port, as well as app support. In addition to Bluetooth connectivity, there is a USB Type-C port for wired connectivity and to charge the internal battery. The manufacturer's warranties are limited to physical defects in the materials, parts and workmanship used in making the product. Given my failed disassembly attempts, I am using Qudelix's own photo of the PCB employed with the 5K. Despite the fact that the body is made of plastic, with the exception of the clamp, its high rigidity gives a rather hard feeling.

We want the device to work as a universal DAC/AMP for both high-sensitivity IEMs as well as high-impedance open-back headphones. Qudelix is a new American company, set up by the former lead engineer of the now famous Earstudio ES100. There are various screens that can be accessed by the corresponding icons at the bottom bar, each for a different hardware or software configuration.

On it are written, in white ink, the model, where it has been manufactured, as well as the different certifications that it complies with. In any case, I like very much, that austere, simple but ingenious presentation and so reduced in size.

To find some differences you would have to go to great files, very well recorded music and use the best headphones you have. other such companion apps for BT DACs are the Parametric EQ (I don't need it at all, but some might, it can even transform certain headphones that have issues), and the Transparency mode, AKA "Mic Pass-Thru" (which is amazing). g. with Foobar2000, it will be necessary to choose the "WASAPI" (push) or (event) output and 24-bit. Same here, not much to comment - even though it's plastic + metal clasp, the built quality is very SOLID. Purely, does it sound transparent or is there some compromise to the sound in exchange for features.This is what most people will see in use, so I do admire the company for going with minimalist branding and letting the product speak for itself. I've tried numerous suggestions and "fixes" online, I even exchanged it thinking it was a lemon - no luck, when it comes to BT stability in many conditions, the BTR5's BT implementation is in itself a LEMON.
