iBasso were fast enough to adopt another brand DAC chip and they have released a successor DAP named DX320.
The iBasso DX320 builds on the legacy of the DX300 with the new DAC chip, even faster operation, the latest Android version and the same swappable AMP card system.The iBasso DX320 is visually identical to the DX300 but inside it packs two pieces of the BD34301EKV DAC chip, developed as a part of ROHM’s high-grade MUS-IC series representing the pinnacle of audio ICs.
Third time’s a charm for iBasso Audio building reference open-back headphones. SR3’s 150ohm impedance, carbon fibre diaphragm, tesla magnet and 4.4mm stock cable adapts to many modern audiophile sources, for flexible quality every way you listen.SR3’s carbon fibre diaphragm one-ups its iBasso predecessors’ biocellulose units, with the stiffer large driver now combining a more pistonic motion at low frequencies with a material that is still self-damped up high.
INTERNATIONAL SHIPPING NOTICE
If your order is being delivered to a location outside the European Union, there is a possibility that you may incur additional charges such as VAT (Value Added Tax) and, if relevant, customs duties within your country.To ensure transparency, in the event that Audioline LTD is obligated by law to collect VAT, the inclusive price will be displayed during the checkout process.For more detailed information regarding these potential charges, we recommend reaching out to the tax and customs authorities in your country. They will be able to provide you with further clarity and guidance on this matter.

The DC04PRO combines many well selected parts and advanced technologies, such as dual CS43131 flagship DACs, dual RT6863 high current output OPAMPs, synchronous DC-DC converter, ultra-low noise LDO, FPGA, KDS Femto second oscillator, multi-functional APP, pentaconn 4.4mm balanced socket, CNC aluminum case, and tempered glass panels. All of these are forged into a USB DAC & AMP with high output power, high current output, dual output interfaces, interchangeable cables, excellent power consumption control, and outstanding specs.
The Cirrus Logic flagship DAC CS43131 provides outstanding performance and excellent sound. With the ultra-low noise LDO that has a 100dB power supply noise rejection ratio to ensure the power purity for the DAC chips, results in an amazing sound quality with a superb black background for the DC04Pro.
The iBasso AMP14 uses one 6th generation triode Nutube 6P1, also found in the AMP13, as a voltage amplifier but now is followed by a JFET differential converter to realize a differential output.
iBasso AMP14 adopts two JRC volume control chips which form a total of 4 channel true balanced volume control.
The signal then passes through the 4 channel balanced output buffer stage to give 5.2V RMS from the 4.4mm headphone socket while there is also a dedicated balanced line output with 1.8V RMS, which is much lower than the 4V industry standard.
In case that you need a full scale 4V balanced line output then you should consider AMP12.
For the DX170, iBasso decided to use two CS43131 DAC Chips in a fully balanced configuration.
The CS43131 is a well known entry level DAC chip which suffered from a temporary shortage but it is now back to production.
The iBasso DX170 utilizes the FPGA-Master technology developed by iBasso. The FPGA-Master, as the audio system controller, directly requests audio data from the SoC, and plays a major role in signal reproduction and maintaining signal integrity. It synchronizes and generates all audio clocks at the same time utilizing two NDK femtosecond oscillators to achieve a fully synchronized single clock source. The FPGA and NDK oscillators also reduce jitter to an extremely low level, building a clean digital audio signal.
The DX170 supports bit-perfect playback up to 32bit/384kHz, native DSD up to 256x and full 8x MQA decoding
