Qudelix 4+

I rarely write reviews, but this tiny magical device paired with this wonderful app deserves thousands of great reviews.

The app works like a charm! It provides you with more functionality and options than you would ever need. I don’t feel qualified to comment about all the features, but so far, I have been an extremely happy customer as this device/app has helped me bring my £1000 pair of in-ear monitors to life thanks to the excellent sound quality of this DAC/amp and software combo and precise EQ which has allowed me to fine-tune my IEM to my liking. Also, you get regular app and firmware updates which is another great plus.
Thank you Qudelix!

I bought the qudelix 5k originally feeling somewhat skeptical but it has went above and beyond my expectations, the app is incredibly functional that gives me full control over even the littlest part of the amp, the app is smooth and bug free. I would prefer a slightly nicer ui but as it is, it’s almost perfect

The Qudelix 5Kis an enthusiast-focused product and this app certainly delivers wonderfully there. So many parameters available there, well presented and well explained. Even the warranty of the product is managed through the app. I wished more consumer products offered this level of support. UX is certainly not perfect but it does the job well. Well deserved 5 stars!!
