5K Bluetooth USB DAC AMP with LDAC, aptX Adaptive, aptX HD, AAC (Dual ES9219 3.5mm Unbalanced & 2.5mm Balanced Output)

This amp/DAC is extremely compact yet packed with features. The built-in 10-band parametric EQ (PEQ) is a game-changer for those who like to fine-tune their headphones. It also includes several preloaded EQ presets, including those from Oratory1990, making it even more versatile. I use it with my Arya Stealth and ZMF Bokeh, and it provides ample power to drive both. However, when using EQ with a negative preamp gain, I do need to maximize the volume to reach my normal listening level. Overall, very happy with the purchase - highly recommended.

Omg! The software just makes it worth every penny! Very professional.

Has a lot of options and dsp is brilliant. Would recommend it its a small package with loads of power

Not impressed, tried with my moondrops, was not blown away, its a decent bluetooth dac. but for this price, it don't think so. Couldn't return as it was an international purchase out of the return window.

The price-to-performance ratio is insane. I have several other products to compare with, such as the Chord Mojo 2, Chord Hugo 2, Audioquest Dragonfly Cobalt, Red, and more. The Qudelix 5K doesn’t quite keep up with Chord’s products, but then again, they’re not even in the same price league… That said, it’s clearly better than most of the gear I test it against. The versatility and sound quality are superb!!! I primarily use it as a headphone amp/DAC for the PS5, connected via the PS5’s front USB-C port. The headphones I most often use for gaming are the Sennheiser HD560S, and they sound really good together. I’ve also tried connecting it through the USB-C port on my iPad. Works flawlessly and even drives my Sennheiser HD600 impressively. This is through the unbalanced 3.5 mm output… I haven’t tried the balanced 2.5 mm output yet, but that would be really interesting.

Deze bluetooth DAC overtreft mijn verwachtingen: heel detailrijke klank, mooie textuur en timbre. Ik gebruik hem voornamelijk met een Queen Of Audio Vesper IEM en een Sennheiser/Drop HD58X hoofdtelefoon. Voor geen van beiden heb ik EQ nodig met de DAC. Zelfs een 30 jaar oude Sennheiser HD480 II klinkt, met slechts een beetje lift in de lage tonen, beter dan ooit tevoren. Het belangrijkste verkoopsargument van de DAC is de EQ, maar die is voor mij minder belangrijk, de instellingen in de app zijn zeker zo interessant. Er zijn enorm veel mogelijkheden. Een raad voor nieuwe gebruikers: doorloop aandachtig alle instellingen. Zoniet zal je enkele cruciale functies over het hoofd zien, zoals de 2 volumeregelingen in cascade. Uiteraard zijn er beperkingen: een hoog-ohmige hoofdtelefoon zoals de Sennheiser HD250II (300 ohm) is weliswaar nog net aanstuurbaar, maar daarvoor is de DAC niet gemaakt en dan moet hij echt "zwoegen". De bediening is een beetje wennen omdat de knoppen geen labels hebben, maar daar is een oplossing voor: de Qudelix 5K sticker by Sproketz.

This is such a good, balanced product in terms of features and price. But if you want better sound you can find it if you pay more. - it has good sound quality - it has great bluetooth connectivity, I can use it in different rooms, different floors, outside my bt source - LDAC significantly better sound quality than other bluetooth codecs, if you connect to mac or iPhone, use wire, because other codecs are hurting sound quality - I have it connected to 3 devices at the same time! 2 by bluetooth and one by USB and it picks the one that playes quite well. - I switched it eventually to be connected to mac by USB, same mac by Bluetooth and am Android phone, because mac does not support LDAC it hurts sound, but sometimes I just disconnect usb and go somewhere, so it switches from usb source to bluetooth in matter of seconds Connectivity of it is so much better than any other bluetooth device I have. Bose 700 does not connect half the time and take a minute to connect if it does, Topping G5 take a bit. This connects in a second, click, connected. The way how buttons are setup takes a bit of getting used to, app is good for nerds and equalization if you want to push your headphone somewhere else, but don't to make a reference headphones a consumer (V frequency response) curve headphones usually can't do that and it would only increase distortion and loose control. Battery life is better than Topping G5 which is 5 times the size and weight.

so happy to be able to keep using my Shure earphones on the go when I was forced to upgrade away from my 3.5mm jack equipped phone. The sound is absolutely just as good as when wired!

The Qudelix - 5K is really a wonderful small HIFI component, which I have now been using for one year. Its extremely compact and light weight, so one can easily clip it to a pair of open back headphones, the range of codecs supported and the stability of the connection are excellent, the companion app offers many settings and customization option, the EQ tool is great and easy to use, one can also use it as a desk dac/amp while preventing the (over)charging of the battery, etc, etc... Everything that Qudelix and other reviewers say about that product and its qualities and functions is true. Honestly, I can't think of anything negative to say about it. The best audio equipment purchase I have made in years !
