Score: 4 / 5 Excellent
The iBasso DX320 MAX Ti is a flagship, limited-edition Digital Audio Player (DAP) crafted in a strict production run of only 888 individually numbered units worldwide. Housed in a precision CNC-machined titanium chassis, the DX320 MAX Ti builds upon iBasso's reference "MAX" platform, combining portable convenience with true desktop-grade amplification and conversion power.
At its digital heart, the player utilizes a quad-DAC matrix featuring 4 x ROHM BD34301EKV MUS-IC™ DAC chips operating alongside iBasso's proprietary FPGA-Master technology. To completely eliminate interference, the digital and analog sections are powered by independent, isolated battery systems. Controlled via a 5.0-inch Full HD IPS touchscreen running dual Android 11 and Linux-based Mango OS, the DX320 MAX Ti features a custom 24-step 4-wiper analog stepped attenuator volume wheel and a 4-position physical gain selector.
KEY FEATURES & PROPRIETARY TECHNOLOGIES
- Quad ROHM BD34301EKV DAC Architecture: Four flagship MUS-IC™ series DAC chips operating in parallel deliver an ultra-low noise floor, 125 dB SNR, and exceptional spatial separation.
- Super Class A Discrete Amplification: Transistor-switched Class A discrete circuit delivers up to 9.0 Vrms via balanced output without step-up voltage boosters, eliminating crossover distortion.
- Patented Dual Independent Battery Power Supply: Completely isolated power rails feature a dedicated 4-cell +/-8.4V battery pack for the analog amp and a separate high-capacity cell for the digital processing board.
- 24-Step 4-Wiper Analog Stepped Attenuator: Physical custom analog volume attenuator with < +/-0.1dB channel imbalance ensures pristine signal purity at any listening level.
- 4-Position Physical Gain Switch: Rotary gain control allows precise power matching for ultra-sensitive IEMs up to demanding full-size planar magnetic headphones.
- Aerospace-Grade Titanium Chassis: High-rigidity titanium enclosure providing superior RF shielding, structural resonance damping, and lightweight durability.
- Dual Boot OS (Android 11 & Mango OS): Switch between open Android 11 for streaming apps and iBasso's dedicated Linux-based Mango OS for pure offline audio playback.

Our Grading Guarantee
All equipment listed on this site undergoes a multi-point inspection by our staff. While we use a standardised 1–5 Grading Scale, please note that "pre-owned" implies some degree of previous life. We strive for transparency and use the following terms:
- Visual Inspection: Condition grades are subjective but applied conservatively. We provide high-resolution photography of the actual unit for sale (no stock photos). We encourage buyers to zoom in on all images as they constitute part of the formal product description.
- Functional Testing: Unless labelled Grade 1 , all units have been tested for power, input/output integrity, and basic mechanical operation. Vintage units (20+ years) are tested for "period-appropriate" functionality; unless specified, internal components like capacitors are original.
- "Fair" Exclusions: Items graded 1 (Fair) are sold strictly for parts or repair. These items are ineligible for returns, refunds, or "Item Not as Described" claims regarding their condition.
- Return Window: If a unit arrives in a condition significantly different than its assigned grade (e.g., a Grade 4 unit arrives with a shattered faceplate), you must notify us within 24 hours of delivery.
