XDUOO ROHM BD34302EKV-E2 DAC Card Module
The XDUOO ROHM BD34302EKV-E2 is a modular flagship DAC card designed for the XD05 Pro and TA-32. It upgrades the existing DAC section with ROHM’s second-generation MUS-IC BD34302EKV-E2 converter, delivering higher resolution, lower distortion, and a more refined sonic presentation while retaining full compatibility with the host device. Installation requires only screws—no soldering is needed—allowing users to easily swap modules and explore different sound signatures.
ROHM Second-Generation MUS-IC Flagship DAC
At the core of this module is the ROHM BD34302EKV-E2, the second-generation flagship chip from the MUS-IC series. It features improved DWA (Data Weighted Averaging) algorithms that enhance THD performance and support HD monaural mode for higher resolution and more natural sound quality. The chip delivers a typical SNR of 130 dB and THD+N of –117 dB, providing a blacker background and greater detail retrieval compared with previous generations.
High-Resolution PCM and DSD Support
The BD34302EKV-E2 supports PCM from 16-bit to 32-bit at sampling rates up to 1536 kHz and native DSD up to 22.5 MHz (DSD512). Note that the final playback capability is limited by the USB interface of the host unit (XD05 Pro / TA-32 typically maxes at 768 kHz). Digital filters include preset, custom, and external FIR options with sharp and slow roll-off characteristics for flexible sound tuning.

Easy Screw-In Modular Design
The module is engineered as a direct drop-in replacement for the original DAC card in the XD05 Pro and TA-32. Installation involves only removing and reinstalling a few screws—no soldering or complex modifications are required. The design remains fully interchangeable with other xDuoo DAC modules, allowing users to switch between different sonic profiles quickly and safely.
Refined Sonic Character
Users and beta testers describe the BD34302 module as offering a warm, smooth, and balanced presentation with natural vocals, smoother treble, firmer bass, and an expanded soundstage. The improved resolution and lower noise floor bring greater texture and spatial information while maintaining the musical, non-fatiguing character associated with ROHM MUS-IC chips.
Op-Amp Rolling Compatibility
The analog output stage of the host devices continues to support op-amp rolling after the DAC module is installed. This allows further fine-tuning of the overall sound signature by combining the new ROHM DAC with preferred operational amplifiers.
