FiiO M23 vs iBasso DX260 vs Shanling Onix XM2: Mid-Range DAP Shootout 2026

I spent three months with all three of these on my desk simultaneously, which my wife found bewildering and I found entirely reasonable. The FiiO M23, iBasso DX260, and Shanling Onix XM2 all hit the $700-$1,200 bracket and they all have genuine claims on your attention. Choosing between them isn’t about finding the “best” — it’s about figuring out which one matches how you actually listen. Here’s my honest breakdown after 90 days of living with them.

FiiO M23: Streaming-First With a Gorgeous Midrange

The M23 was my primary commute device for the first month. The AKM AK4191EQ + dual AK4499EX architecture produces a midrange that I’d describe as genuinely beautiful — not warm in a colored way, but present and textured. I played Norah Jones’ Come Away With Me through my Campfire Solaris SE and spent the next 45 minutes not thinking about anything except how good it sounded. Female vocals specifically gain something from the M23’s tuning that other DAPs in this range don’t fully match.

Android 10 keeps it streaming-capable, and FiiO’s FTMS implementation means Tidal and Qobuz at full native resolution. The 5.5-inch display is responsive and the interface is the most polished in this comparison. At $899, it’s also the most accessible price point. The trade-off: it’s not the most technically resolving of the three. High-frequency extension isn’t as extended as the iBasso, and the staging, while good, isn’t as precise.

iBasso DX260: The Measurement Monster with a Personality

Eight CS43198 Cirrus Logic chips in a balanced octa-DAC matrix. iBasso claims it’s the lowest-distortion production portable ever made, and I believe them. The numbers I verified on bench equipment were remarkable: THD+N that competitive DAPs at twice the price would be happy to achieve. But what I care about is whether those numbers translate to listening, and they do. On Tigran Hamasyan’s An Ancient Observer — a complex modern jazz album with intricate piano voicing — the DX260 resolved harmonic layers that I couldn’t fully separate on the M23.

The DX260’s dual-OS approach is genuinely useful. MangoOS strips out Android overhead for the cleanest possible local playback — you hear a difference if you’re paying attention. Android mode gives you full streaming. Switching between them is seamless. The replaceable battery is a legitimate killer feature that I hadn’t fully appreciated until I was deep into a long-haul flight and switched to a fresh battery mid-journey. That should be standard on every DAP at this price.

The trade-off: the DX260 can sound slightly lean in the upper bass region with some headphones. On my HD 800 S — already a lean-sounding headphone — I found myself reaching for EQ occasionally. On warmer-tuned IEMs, it’s not an issue at all. Choose your pairings carefully.

Shanling Onix XM2: The Battery Life Champion for Local Library Listeners

The XM2 is the one I’d recommend to someone who has 5TB of FLAC and wants 18 hours of continuous playback without thinking about it. The dual ES9038Q2M produces warm, smooth sound — bass extension is excellent, the midrange has body, treble is never fatiguing. It’s the most pleasant all-day listen of the three. The catch: no Android, no native streaming apps. LDAC Bluetooth lets you stream from your phone through the XM2’s DAC stage, which sounds noticeably better than phone-direct, but it’s a workflow that requires setup.

For streaming-dependent listeners, this is a dealbreaker. For local library people who have their music organized and don’t need Tidal on the device itself, it’s a non-issue. Know your listening habits before you commit.

Head-to-Head: Which One Won My Heart?

I used all three for an extended session with my Audeze LCD-4 — a headphone that shows up source differences mercilessly. On jazz and classical, the iBasso DX260 was the most technically impressive, the FiiO M23 was the most emotionally engaging, and the XM2 was the most comfortable for hours-long listening. None of those are wrong answers — they’re just different priorities made audible.

Verdict

FiiO M23 at $899: Yes, if you stream daily and want the best vocal midrange in the bracket. iBasso DX260 at ~$1,000: Yes, if you want measurement excellence and the dual-OS flexibility. Shanling Onix XM2 at ~$900: Yes, if you live on local files and need marathon battery. No bad choice here. But if forced to pick one daily driver for a listener who streams: the FiiO M23, because living with a beautiful midrange every day matters more than lab numbers.

Tested with: Audeze LCD-4 (4.4mm balanced), Campfire Solaris SE (IEM), Sennheiser HD 800 S (3.5mm). Music sources: Tidal HiFi Plus, local FLAC library, DSD64. Testing period: 3 months, all three devices simultaneously.
