V12 Current
V12 · Infinity Player · DX340 + DX340Max + DX320MAX + DX320 + DX270 + DX260MK2 + DX180

What's New in V12

Out now: UPnP/DLNA from your phone, Internet Radio, Listening Profiles, Rsync and WiFi Transfer, plus Local Mode and a visibly faster, smoother UI.

All changes (10)
  • iBasso DX320 supportAmp cards with Line Out and gain, both batteries in the status bar, Digital Filter, DSD Filter and PCM DSD Volume Match. Infinity DSP runs in both Android mode and Infinity Pure. Device matrix →
  • UPnP / DLNA — play to your DAPPlay gapless, DSD included, from BubbleUPnP, mconnect, JRiver, Audirvana or foobar2000, and browse the library. The queue lives on the DAP; closing the app won't stop it. See it →
  • Internet Radio87 stations built in (SomaFM, NTS, some lossless), plus your own links, live artist/title and .m3u import/export. Browse tens of thousands more by name, genre or country. See it →
  • Listening ProfilesSave a headphone's whole setup — Harmonic, NOS/OS, filters, gains, EQ, PEQ, Tube/Vinyl/Chassis, DSD Remaster or HRR, Boot and Stage — and restore it in one tap. See it →
  • Rsync serverSync music from a computer or NAS: only new or changed files copy, interrupted runs resume, the library updates itself. Built-in guides: Windows, macOS, Synology, command line. See it →
  • WiFi Transfer, on its own pageSwitch, QR code, address and free space (internal and SD card) in one place. Uploads, moves and deletes, even from Folders, reach the library in seconds — no rescan.
  • Local ModeOne switch for offline listening: Wi-Fi and Bluetooth stay off, even after an app restart, streaming buttons grey out and network features pause until you switch back.
  • Faster, smoother UIVisibly quicker than V11: unused telephony daemons stop after boot, two crash-loops gone, lower idle CPU, GPU clock held during playback. Lists scroll without stutter; transfers no longer pause playback.
  • Harmonic: live OFF, and it stays onHarmonic OFF no longer reboots the DAP: the FPGA stops shaping instantly and system tuning returns to stock. Fixed: Harmonic silently switching off seconds after every boot.
  • Device Info: voltage graphsMain and Amp battery rows graph five minutes of voltage and swing: how hard the amp pulls each cell. Current in mA on every model; Settings opens with network tiles.

What's New in V11

Infinity DSP v2: physics-modelled Tube, Vinyl, Chassis, in Android mode too — plus Parametric EQ, public Ultimate Enjuku, DX260MK2, AMP19 and 2× faster track changes.

All changes (12)
  • Infinity DSP v2 — Tube EngineSix tubes (2A3, 300B, EL34, KT88, 6L6, 12AX7) modelled from real plate curves: harmonics come from the tube, not presets. Subtle, Classic or Lush, plus Smooth Mode. See it →
  • Vinyl EngineRebuilt on record physics: three turntable setups — Vintage ’60s idler/conical, Classic Hi-Fi belt/MM, Audiophile quartz-DD/MC — plus Record Condition, Analog Harmonics, stylus tracing and 33⅓-rpm-locked wow.
  • Chassis EngineThree chassis — Copper, Stainless Steel, Titanium — differ where real ones do: background blackness, image width, and how long the material rings. The music passes untouched.
  • Parametric EQTen parametric bands on a live response graph you drag, one-tap AutoEQ/oratory1990/Squig import, a built-in filter-type guide, and an Intensity slider on the 10-band EQ. See it →
  • Introducing Ultimate EnjukuA second FPGA image for the DX340 and DX340Max, with its own sigma-delta character and no unlock code. The Harmonic Exciter runs on top; each preset has a one-line description.
  • iBasso DX260MK2 SupportInfinity Pure, the full Infinity DSP suite in both modes, five CS43198 digital filters, Low/Mid/High gain, Line Out switching and its own wallpaper. Full matrix →
  • AMP19 Support (DX340)iBasso’s tube-hybrid card: the Output switch shows its two stages, Super A / Tube, the Now Playing badge follows, and DC-IN SuperGain engages through the card’s own gain stage.
  • Infinity DSP in Android ModeTube, Vinyl, Chassis, Crossfeed and Invert Phase no longer need Infinity Pure: they apply live and debut on DX180 and DX320MAX. DSD Remaster and HRRAI still need Pure.
  • Device InfoSoC, DAC, firmware and module version; live CPU/GPU/RAM; flash type and health; both batteries' cycles and health (SOH) from the fuel-gauge chip; every key temperature. See it →
  • Faster, Fuller PlaybackTrack changes in ~0.6 s, not ~1.3 s; CUE tracks near-instant; MP3 dynamic-range scans 68× faster. With DSD Remaster off, all four CPU cores serve playback: fuller bass, steadier sound.
  • Library & TagsA SONGS tab on every category page, LOVE-list sorting, clean multi-artist credits instead of “A;B”, file size in the Tags panel and L/R balance up to ±20.
  • FixesNo more AMP16 AB → Tube channel drop, DX320MAX black screen entering Infinity Pure, app restarts on phantom SD-card events, or static switching DSD → PCM with DSP on.

V10.5
V10.5 · Infinity Player · DX340 + DX340Max + DX320MAX + DX270 + DX180

What's New in V10.5

Invert Phase, a Missing Tag fetcher, TrueNOS on DX340Max, duplicable Harmonic profiles, full Amp16 support, queue-to-playlist, redesigned Now Playing, Software Volume and Volume Knob.

All changes (11)
  • Invert PhaseFlip both channels' absolute polarity from Infinity DSP — for pressings and transfers cut out of phase. Level and timing don't change. Details →
  • Missing TagFinds tracks with incomplete metadata, fetches candidates from several sources and lets you review each field. Nothing is written to your files until you say so.
  • TrueNOS on DX340MaxThe DX340Max gets true non-oversampling: the DSP comes fully off the factory oversampling path, not an approximation — as on the DX340.
  • Duplicate Harmonic ProfilesCopy any custom Harmonic profile and tune the copy — A/B a variation against the original without rebuilding all nine bands. DX340 and DX340Max only.
  • Amp16 SupportFull compatibility for the Amp16 card — detected on boot and given its own amp tuning, alongside the amp modules already supported on the DX340 family.
  • Queue → PlaylistSave whatever is playing right now as a new playlist in one action — the whole queue, in order, without rebuilding it track by track.
  • Software Volume & Volume KnobSoftware Volume Control for devices and outputs without hardware attenuation, and Volume Knob Control to map the physical knob your way.
  • Tag Details on the Track PopupThe track popup now shows the full tag set — every field the file carries, without leaving the list you are browsing. Tap a track to open it.
  • Redesigned Now PlayingAlbum art on an ambient glow, DSP and DR chips in one row, format and ReplayGain below the seek bar, dual battery up top, persistent bottom bar. See it →
  • Playback StabilityAudio work now runs off the main thread, removing a class of UI crashes during playback. After a restart the player resumes at the exact position it stopped at.
  • FixesUSB-DAC charging fixed, DeepSleep no longer causes a very slow reboot, and Now Playing lays out correctly at large font sizes.

V8
🆕 V8.0 Change Log · DX340 + DX340Max + DX270

What's New in V8

The biggest leap since launch — native Qobuz hi-res streaming joins Tidal, and NOS / OS DAC modes give you direct control over the interpolation filter. And for the first time, DX270 is fully supported alongside DX340 & DX340Max.

All changes (4)
  • Native Qobuz IntegrationStudio-quality FLAC up to 24-bit / 192 kHz, streamed bit-perfect through the iBasso Native Driver alongside Tidal. No transcoding, no Android resampling — the file Qobuz serves is exactly the file your DAC plays.
  • NOS / OS DAC ModesSwitch the DAC's interpolation filter in real time. NOS (Non-Oversampling) for the raw, direct character. OS (Oversampling) for the smooth, reference sound. Both are bit-perfect to the file — the choice is preference, not fidelity.
  • Interpolation RateThree voicings on the CT7302 — Smooth (2×, warm and analog-leaning), Balanced (4×, natural and detailed), and Detailed (8×, crisp and airy, the iBasso default). All bit-perfect to the file. DX340 & DX340Max only.
  • DX270 Support First with DX270
    Anantar Ultimate reaches the iBasso DX270: EXT4 support, kernel boot profiles and the full Infinity Player. One module, three players.
