R2R on the go - Analog Magic in a Modern Portable CD Player

Fiio tries to capture that warm vintage sound with their new portable CD player. And they really are investing a lot of money into improving and adapting their R2R technology. And it is becoming an important staple into Fiio arsenal, on the box itself there is no Fiio logo, there is only R2R that is what they want to preserve to future buyers and listeners. You are listening to specially R2R product made by Fiio.

I already spoke about how Fiio is building sort of “house sound” for all their future products, and more you can actually read/watch my review of Fiio K13 R2R DAC, and link will be in description of this video. But there is a lot of advantages of smoother and warmer sonic signature, which works well with many systems, and helps with all kinds of production from bad to great to sound better.

Specs, Build Quality, Features and Ergonomics

The FiiO DM15 R2R is a modern portable CD player that doubles as a high-res USB DAC, balanced headphone amp, Bluetooth transmitter, and CD ripping machine, all packed into a sleek, portable chassis aimed at listeners who want premium sound without being tied to a full desktop system.

This is all trying to give flexibility to modern listener. Many of us had CD rippers as standard thing in PCs back in day, now nobody have them anymore. So this can easily become your CD ripper. It also serves as not just CD player, but to use it weirdly enough as purely DAC to improve other aspects of your hifi system, and even to play DSD files through it. Lot of great things, that this helps not just as portable device but also as quasi desktop variation as well.

This unit uses a custom fully differential 24-bit R2R resistor-array DAC built from 192 precision resistors to recreate a warm, analog-like sound signature. It supports USB DAC up to 384kHz/32-bit and native DSD256, balanced and single-ended headphone outputs, digital outputs, and a robust 4700 mAh battery for about 7 to 10 hours of playback. Balanced power reaches up to ~1150 mW per channel into 32 Ω, giving enough oomph for demanding headphones. I think this is more than enough power for most headphones to be driven comfortably.

The DM15 R2R features a premium aluminum chassis with a transparent tempered-glass top that shows the spinning CD, giving a pleasing retro aesthetic. An LCD shows track info and settings. Overall build quality feels robust and durable, significantly better than generic portable CD players.

Great Size, and weight, but problem with usability

But I have a lot of problems here, buttons are small, round, and there is no tactile feeling to them. Which makes hitting the right buttons a chore, as always I had to lift the CD player to look at layout of buttons and carefully click on them. To play, pause, next track etc.

And I think that is because they tried to put too many things in that front panel. There is a screen, those main control buttons, volume knob, there is also 3.5 and 4.4 mm headphones output. There is also a button to switch between CD and USB DAC. There is also Bluetooth, SPDIF out, pre out. And magic bass 1 and 2. All of these I can see being used for versatility sake, except that magic bass I just don’t like that. I used it just to test it a little bit, and sound got distorted so much, that I really do not understand why would anyone listen to music like that. But maybe I am wrong here, I will leave that as an open point.

But with Desktop mode which is taken from other Fiio DAPs, it helps bypass the battery and to be used as a desktop CD player, not using the battery so much prolonging its life.

There is also various EQs that you can change on click. On paper this seems like really great thing, that most functionality is on click, rather than on additional menu button like on other CDs. But.

There is like all you need at this front panel, so much for you to choose and do, but all of them make the important buttons so small and hard to interact with them, that they needed here better architecture of information to drive industrial design.

But they sort of found a way to help with this situation, with inclusion of remote control. Yes remote control, you can interact with CD player without physically touching it. So it does help, buuuut I walk a lot of times with my CD players, and usually I just don’t know where remote is, because I go from room to room and don’t carry it with me.

Regarding to back of the device, there is a coaxial and balanced in. There is also USB for connecting external devices to its DAC. And Bluetooth which I think is also an important part of this devices is all the great flavours of aptX HD, adaptive etc.

But overall it is small enough, slim enough and light enough to be easily carried around. I love the form factor a lot here, if you can get those great leather covers for them they look beautiful.

Sound Quality

Regarding sound, if you look for R2R CD Player, that cost around 270 dollars, which is an amazing price point. Then go out to buy this player right now. You will not be able to find player in this category that is R2R that sounds this good, and cost this much.

The signature of the DM15 R2R is defined by its custom fully-differential 24-bit R2R resistor-ladder DAC, which aims to deliver a more natural, analog-like musicality compared with the more common delta-sigma DACs found in most portable players. This design choice generally results in a sound that many audiophiles describe as warmer, smoother, and more organic, especially in the midrange and lower frequencies.

So as you can expect bass is warmer and smoother. The lower midsection and upper bass is giving easy going smooth presentation, especially seen in vocals, mostly male vocals. The DM15 R2R tends to have a slight warm tilt, giving rich, full mids and bass that make vocals, acoustic instruments, and jazz textures feel more engaging and forward-leaning.

Bass has good weight and presence, with enough impact to give rhythm sections a satisfying sense of momentum without feeling boomy. The unit’s optional Bass modes and multiple EQ presets let you dial in a stronger low-end if you prefer more impact, though boosting bass can slightly affect midrange clarity — as is common with simple bass-boost circuits.

But as everything else your headphones, if they are clear, or bright might benefit from this. Even if you want big large bass your headphones needs to be talented enough to reproduce that bass.

This is decently clear CD player, but don’t expect that it tries too hard for it to be very transparent and with utmost black background. But it does conduct the instruments on soundstage to be clear and vivid enough. It makes the instruments sound weighty and more impactful, but yet very rounded in soundstage.

While the R2R architecture emphasizes musical flow and analog texture, it doesn’t mean detail is absent — microdetails and subtle harmonic textures remain present, but the overall presentation isn’t as clinical or hyper-analytical as some delta-sigma DACs. Instead, the focusing is on organic coherence and relaxed detail retrieval.

And soundstage is rather decent, actually I really liked it. It helped lower register open more, and when that happens it usually spreads the instruments more, as same like adding a sub opens the soundstage more. And with any talented gear that have enough big drivers it will have a great soundstage.

DM15 R2R isn’t tuned for reference-neutral accuracy. Instead, it offers a musical, smooth, slightly warm and analog-leaning sound character with satisfying bass density, a relaxed treble, and organic midrange richness. This makes it particularly appealing to listeners who value musical engagement and warmth over hyper-analytical neutrality.

Synergy and Pairing

As far as synergy and pairing goes, it is not that hard to understand that this CD player works better with more neutral to bright speakers. But I can see a scenario for someone who enjoy really large, weight and big sound kinda also enjoy this with warmer headphones. As that drive and smoothness will be put to the max, in scale to some clarity and resolution.

Now I had luck in my life that I tried many of the portable CD players. And I will go through them how they differ from DM15 R2R.

vs. Shanling EC Zero T

Maybe the best comparison is the Shanling EC Zero T. It is also a R2R portable CD player, but with addition of tube headphone amplifier. Now let’s go over the big thing it is 300 dollars more expensive. You can actually buy two DM15s for price of the one EC Zero T. Well it does, it is in my opinion better designed with better layout device. It is an incredible spacious and lush presentation that can be warmer and neutral based on what you choose. Its DAC is more capable into decoding bigger file formats including DSD 512.

But there is plenty of ways to model and manipulate sound in EC Zero T, like OS, NOS, Solid State/Tube. When you avoid tubes the sound is neutral and clean, while with tubes it is more lush and warm. It have a stronger headphone amplification so it can drive more headphones easily.

I think all that DM15 does, EC Zero T does a little bit better. But the major question is that worth more 300 dollars. I think in 70-80% cases, especially if you have cheaper headphones, you might not be so much invested in sound differences. But in that other 20–30% the more bass definition you get, the more soundstage you get with great recorded music, and even the great clear sound in solid state mode is worth it. But that is like with any HIFI gear you never get your money worth, but you get more with additional 300 dollars.

vs. Shanling EC Zero AKM

full review: https://www.hifidaydreaming.com/post/new-shanling-ec-zero-akm-is-peak-value-and-quality-for-portable-cd-players-review-vs-fiio-dm13-ec

But there is one thing I want to add here and that is EC Zero AKM. It is also more expensive device, around 40 dollars more. And here is the real battle. EC Zero AKM does something better and something worse.

Firstly off as design wise I like more Shanling, I liked how buttons are obviously placed, and how it is easy to see and understand what they do. Even though many additional options are hidden in sub menu, I rarely use them, so I don’t need them like in Fiio all on control board.

But Fiio have a stronger headphone amplification, both in desktop mode and portable. Fiio have this beautiful smooth sound, more definition in bass. Have this great vocals, and great soundstage.

Shanling on other hand, have much more clarity and details. It just resolves so much better. I think it is more what kind of audiophile you are. Some rock songs, I really enjoyed with Fiio with that definition and drive, and if you like more vocals that are smooth laid back and just lush and beautiful I think Fiio did a good job. But there is more clarity and emphasis of textures in like jazz when you listen with AKM. It just is more fun to analyse and organise music, and just hear all the micro details. It is just cleaner more, open details even more rhythmical. While DM15 is more driven and musical, and passionate.

Here also plays a big role, what kind of headphones you have. While Fiio can play with any headphones, AKM is just too much with really bright headphones. Also in my comparison it seem that AKM can last the longest out of all CD players, the battery just held far more.

vs. Moondrop Discdream 2 ultra

Regarding the Moondrop Discdream 2 Ultra, it is also a similarly priced device. At around 40 to 50 dollars more. It is an interesting player for two reasons. First the build quality while being aluminium similar to Fiio, it is built really rigidly. It really feels like product that can last. And it is also heavier than others.

And secondly off, it uses Cirrus Logic DACs, and they sound the most neutral out of all of them. So we have 2 R2R DACs, one AKM and now a Cirrus Logic. It is great depending on what kind of audiophile you are. It is truly a CD player that I think will work with many different headphones.

But it is a great sounding portable CD player. Truly great soundstage, the instruments on soundstage seems on their plane and their place. Very well organised and you can see how it allows for greater textures that way. To see how something is produced and mastered. It is the most clear CD player out of bunch. Now if you miss more bass definition you can go with Fiio DM15, or more details and extension with Shanling. There is all the flavours in the world for you to choose.

Conclusion/The Most Musical Portable CD Player in 2026

I really love DM15 R2R, I think it is that soft, musical and smooth portable goodness that we need. And with M33 R2R from Fiio it is a cheaper way to carry R2R player with you. There is a lot to love here from sound, and features that it gives to you, to remote, good looking design and build, inputs and outputs. They really gave you a lot for the now in comparison to competitors cheapest price, without sacrificing quality.

In summary, the FiiO DM15 R2R is a feature-rich, well-built portable CD player that brings a hint of analog warmth and modern digital convenience into one package. With its powerful outputs, versatile connectivity, and satisfying sound character, it’s a compelling choice for both CD collectors and listeners seeking a hybrid portable-to-desktop audio solution — especially if you appreciate a musical, engaging sound signature and hands-on control. Even though you do not get the best clarity or detail retrieval in this price range.

I definitely recommend this one.

Keep daydreaming,

See you on a next video
