Everything You Need,
At the Hardware Level
Anantar Ultimate consolidates sound, kernel, and power management into a single unified module â no conflicts, no hassle.
What Anantar Ultimate puts in your hands
Every control lives in the Anantar Ultimate tab of Infinity Player. Tap a screen for the details.
Standard
Harmonic, OverSampling, Interpolation, Infinity Stage, Boot and Infinity FPGA — the core tuning on one screen.
Power
Amp gain, DAC gain, SuperGain, Desktop Pure Power and L/R balance.
Output
USB DAC mode for a computer or phone, Bluetooth, and Bluetooth DAC to receive from a paired phone.
Infinity DSP
DSD Remaster, HRRAI, Crossfeed, Invert Phase, the Vinyl / Tube / Chassis engines and AutoEQ.
OverSampling
TrueNOS, NOS or OS — the CT7302 bridge under your control, switched live.
Boot profile
Analog or Extreme kernel tuning, or Off for stock behaviour. Applies after one reboot.
Harmonic
Twenty FPGA harmonic profiles on DX340 and DX340Max, plus an editor for your own.
Infinity Pure
Hand the DAC to Infinity Player alone. One card, one reboot.
Infinity DSP v2
Physics-modelled Tube, Vinyl and Chassis engines, Crossfeed, Invert Phase, DSD Remaster and HRRAI â in Infinity Pure and Android mode.
Learn more âHarmonic Profiles Engine
Nine bands of even and odd harmonics set inside the DX340 / DX340Max FPGA â bit-perfect, native DSD.
Learn more âInfinity Stage
Five soundstage profiles â Studio, Chamber, Salon, Theatre, Original â each a different heap-memory configuration for space and realism.
Kernel Boot Profiles
CPU governance, power management and audio-thread priority set at boot, for jitter-free listening.
Enhanced Sound Signature
Audio tasks pinned to dedicated CPU cores via interrupt tuning â wider stage, cleaner separation, no latency spikes.
Flawless 32-Bit/192kHz Playback
Native DSD, heavy FLAC and hi-res streams play without stutter or dropouts â the stalling of stock firmware is gone.
Auto Profile Selection
Detects the installed amp card and picks the right default profile. Nothing to configure.
MangoOS Compatibility
Boot profiles, oversampling and harmonic profiles set in Android carry over into MangoOS.
Native EXT4 Support
Mounts EXT4 cards natively, bypassing the exFAT FUSE layer â less CPU, less jitter, more micro-detail.
Learn more âIntelligent Desktop Mode
On a 9â12 V supply the battery leaves the playback path â desktop-grade power without battery noise.
Three Ways to Load Music
USB Mass Storage by cable, WiFi Transfer by drag-and-drop in a browser, or Rsync from a computer or NAS. The library updates itself.
Device Info
Battery cycles and health, storage health, temperatures, CPU / GPU / RAM â read live from the hardware.
Learn more âEasy USB DAC on Tile
One tile turns the DAP into a USB DAC for Tidal, Apple Music or Spotify â with the full optimisation stack.
Seamless OTA Updates
New builds arrive over the air from the Magisk Modules tab or Infinity Player â no PC needed.
Desktop-Class Architecture, Realized
Anantar Ultimate operates at every level of the DX340 / DX340Max / DX320MAX / DX320 / DX270 / DX260MK2 / DX180 hardware stack â from the FPGA and DSP chips up through the Linux kernel and into the Android layer.
Desktop-Class Architecture Realized
- 20 Distinct Harmonic ProfilesThrough direct integration with the FPGA 3.0, Anantar delivers meticulously tuned sound signatures beyond default constraints â for any equipment pairing.
- True NOS ModeFull potential of the CT7302 DSP is unlocked, achieving an authentic Non-Oversampling (NOS) experience â a significant upgrade over the factory oversampling.
- A "Pure Desktop" Power EnvironmentBy leveraging desktop-class power chips (bq24192 / bq25890), the system achieves zero battery noise. When a Linear Power Supply is detected, a clean external power path is provided automatically.
The Purest Signal Path
- Streamlined Kernel-Level SwitchingTwo polar opposite signatures â Extreme and Analog â achieved at the binary kernel level. A reboot finalizes deep-level changes, but Anantar makes switching seamless.
- A Jitter-Free Audio HighwayBy isolating the dedicated audio IRQ, the "thin" sound issue is eliminated â delivering a rich, organic, pure audio buffer.
- 10â20% Performance Gain via EXT4A breakthrough in storage efficiency. Native Linux EXT4 support for microSD significantly reduces system latency compared to standard exFAT.
Craft Your Perfect Sound
Three dimensions of tuning â oversampling, kernel, and harmonic â fully combinable for your taste.
OverSampling Modes
Stock factory oversampling configuration.
Non-OverSampling â bypasses digital filtering for a raw, phase-coherent, and musical sound.
Custom-tuned algorithm for better transient response and reduced ringing artifacts.
Kernel Boot Profiles
Maximizes CPU performance and system responsiveness for the most precise audio processing.
Optimized power delivery and clocking for a smooth, organic, analog-like sound with reduced digital glare.
Reverts system behavior to original factory specifications.
Harmonic Profiles Engine Hardware-Level FPGA
20 profiles in three series drive the DX340 & DX340Max FPGA directly: zero degradation, DSD included. Since V12, Off instantly returns to stock, no reboot.
Water Series
Sky Series
Fire Series
DeepSleep Mode V2
Automated power-management for maximum battery longevity
Activates after 15 minutes of: no audio playback & no USB connectivity.
Deactivates BIG CPU cores during sleep. Triggers 60-second MAX CPU Boost on wake-up.
Automatically disables Wi-Fi and Bluetooth to eliminate idle battery drain.
Screen-on triggers instant state restore â all connections and apps resume immediately, no reboot needed.
View cumulative sleep time and real-time battery discharge rates via new notification.
Deep-level integration instructs the low-level OS to enter deep sleep states more effectively.
Stays out of the way while UPnP, WiFi Transfer or Rsync is switched on, and returns the moment you switch them off.
