After spending some time with the FiiO DISC, I started to realize it does much more than its size and price suggest.
This is a compact digital audio player built around a dual CS43131 DAC architecture and features a touchscreen.

It can deliver a refined output that is clean, efficient, and without excessive power consumption. In practice, it becomes something even more interesting. It's a fast, intuitive device ideal for everyday use, with a surprisingly mature sound.

First Impressions (Sound Signature and User Experience)

With the CS43131 DAC chip it houses, the DISC offers a musical yet controlled signature. It has a rather enjoyable presentation.

The bass is clean and slightly boosted, but avoids unnecessary bloat. It focuses on speed and clarity. The sub bass reaches well when the track requires it, but never feels exaggerated. The mid bass has a subtle warmth that gives body to drums and bass lines, but always remains under control.

The mid frequencies are the range where the DISC shows its character. There's a slight smoothness here, but it's not colored. Vocals are natural, slightly front and very easy to follow. Instruments are well separated and there's a sense of layering you don't always get at this level. It doesn't aggressively force details, but brings them out naturally.

The treble is clean and well extended. It offers a balanced sense of airiness. Cymbals sound realistic, not metallic or overly clear. Long listening sessions are effortless, and that's more important than the initial sparkle.

The soundstage is surprisingly well structured. The width is above average for this class, but it was the depth that impressed me more. There's a clear sense of front and rear layering. The rendering is stable and believable, not artificially exaggerated. You enjoy listening to it.

If I had to summarize the sound signature:

Balanced, Slightly musical, Clean but not sterile, Not tiring, Very consistent

User Interface and Ease of Daily Use

This is where the DISC really stands out, in my opinion.

The touchscreen is responsive, fluid, and easy to navigate. There's no lag that breaks the immersion. Navigating large music libraries feels natural, and the overall user interface design is clean and intuitive. You don't need to learn, you just start using it.

The menus are logically structured. Library browsing, playback controls, Bluetooth settings, and system options are all where you'd expect them to be. There's no unnecessary complexity. At the same time, it doesn't feel limited.

The startup time is fast. Shutting down is equally fast. This might seem like a small detail, but it makes a big difference in daily use. You pick it up, press the button, and start listening within seconds.

FiiO's approach to software updates is also worth mentioning. Over the years, they've earned a reputation for actively supporting their devices. Updates aren't just about bug fixes; they often improve stability, performance, and sometimes even audio behavior. This level of consistency places them among the most trusted brands in terms of long term user satisfaction.

Of course, it's a new device and still not entirely perfect. Minor glitches are quickly fixed by Fiio with updates, but the issues that might bother you during a month of daily use seem to have significantly decreased with the latest update.

Bluetooth Performance and LDAC (Sony Codec) Experience

The DISC's Bluetooth performance is excellent for its class.

LDAC support really makes a difference. When paired with Tanchjim RITA Bluetooth Headphones, the connection remained stable without interruption throughout long listening sessions. The Bluetooth 6 implementation clearly makes a difference here.

The sound quality via LDAC is truly impressive. There is a noticeable increase in resolution compared to standard codecs. It maintains bass control, mid frequencies remain clear, and the highs retain their smooth extension. It doesn't feel like the experience has been compromised.

What impressed me most was the consistency. Whether I was walking around the house or using it outdoors, the connection remained stable. There were no random interruptions, no sudden drops in quality. My wife confirmed the same consistency in daily use.

For a device in this price range, this level of wireless performance is not only acceptable but competitive.

In the online guide, it states:

SBC - Cyan light pulsing

LDAC - White light pulsing

However, inside the app, I can't find SBC, and I only activated LDAC, which should be white. I see the color as cyan but maybe due to the quality of led it's not purely "white".

I'm using it on a Windows with lossless Spotify and Sony WH-1000XM4.
