iBasso DX320

iBasso's newest spawn is proudly liquid and coloured – accurate yet veering from sterility. Sweetly indulgent, like an information-rich fruit cake of a DAP. Soundstage spans forward and spherically for deep immersion and involvement, so the whole musical experience feels unified by a connective tissue.

"What really stands out about this true high-end player are its excellent technical sound performance and its very natural overall presentation" to MOONSTAR Reviews. ichos-reviews praises its flagship completeness. DX320 trades up its digital decoding backbone to a pair of the well-received BD34301EKV. 

An in-house designed FPGA acting as a clock and data-marshaling master supplies pristine I2S to the DACs, which then oversample and decode at a 16X internal rate for peak Nyquist performance and shallow ROHM linear-phase digital filters to be employed. 

Crucially, DX320's BD34301EKVs output analog in current, as demanded by a DAP that claims to be of flagship status. iBasso are therefore afforded the opportunity to tailor the DAP's sonic profile as they wish with a current-to-voltage I/V converter, and the added measure of ensuring that small-signal is of the lowest distortion to begin with.

Volume is controlled via a proprietary iBasso solution, specially developed for these ROHM DACs. So begins DX320's fully-balanced, true differential analog circuit that runs at a massive 16.8 volt operating voltage for linear open-loop operation. Its power stage is fully discrete and boasts buffers capable of putting out 2 amperes of current.

DX320's bridge-tied load operation halves impedance per output phase, but the potent output transistors comprising the power stage mean it's never fazed driving low impedances.

Happily use DX320 with anything ranging from the 3ohm Empire Ears Raven and Odin, up to the 300ohm ZMF Headphones Atrium on stock Amp11 module, or switch out the modular analog card for the yet-more potent Amp12 or tubes Amp13 and Amp14.

With 2.5mm and 4.4mm balanced outputs removing need for cheaply-built, signal degrading adapters for connections to make something fit, your flagships can be juiced to the max potential, signal integrity guaranteed via direct sockets soldered to PCB.

The quantity of output power has been discussed, but the quality's not yet mentioned. DX320's total 6,000mAh power supply component is split into a 4,000mAh battery for the digital sub-system, and separate 2,000mAh unit for the afore-mentioned analog circuit.

Doing so cleans up the lifeblood for clean, quiet audio available system-wide, iBasso touting their custom-made bypass capacitors as a DC filter for purer power yet. 

All the above would mean little if DX320 wasn't built with the future of music consumption in mind. But thankfully Android 11 makes its appearance to be at the cutting-edge of DAP UI, processed by the speedy Snapdragon 660 SOC plus 6GB of RAM for smooth operation. 

16X Tidal MQA and Apple Music will be streamed at bit-perfect level via Direct Transport Authority (DTA), bypassing otherwise mandatory and detrimental Android re-sampling. DX320 was the complete package to Major HiFi and deservedly took their Gold Award.

Thus is DX320 – iBasso's most complete and most advanced line music player – released, designed to tackle every one of the modern audiophile's needs. Also shop iBasso's other releases here, or all our other music players here.
