Unboxing and First Impressions
The xDuoo TA-32 arrived well-packaged, containing the unit itself, along with several accessories. These included tubes (the 5U4G rectifier tube, and a matched pair of 12AU7 tubes), a power cable, screwdriver, and screws for the swappable DAC card. There were also various cables – a USB type A to female USB type B, a Bluetooth antenna, and a 6.5 mm to 3.5 mm headphone adapter.
The unit itself is a solid, weighty piece of equipment. The build quality feels premium and the brushed metal finish is attractive. The rear panel is packed with connectivity options, promising diverse usage scenarios.
Immediately, the xDuoo TA-32 gives the impression of a high-quality audio device. The included tubes add to the classic audiophile aesthetic and hint at the warm, detailed sound they promise.
Connectivity and Features
The xDuoo TA-32 offers extensive connectivity. On the rear, you'll find balanced and unbalanced analog outputs (selectable between DAC and tube stages), along with balanced and unbalanced inputs for external devices. Digital inputs include USB, optical, coaxial and AES/EBU.
The front panel features a volume knob which also acts as an input selector, alongside balanced (4.4mm and 4-pin XLR) and unbalanced (6.5mm) headphone outputs. This flexibility accommodates a variety of sources and headphones.
The swappable DAC card is a significant feature, allowing users to upgrade to higher-end DAC chips, such as the AKM 4499EX, for even better audio quality. The included ROHM BD34301 DAC already provides a great foundation.
Sound Quality and Listening Experience
The xDuoo TA-32 delivers a warm, rich sound signature. Both the DAC and tube outputs offer excellent sound staging, but the tube output provides a noticeably warmer and more natural presentation.
I tested the TA-32 with various sources and headphones, consistently impressed by its detail retrieval and spacious soundstage. The tube output is particularly suitable for listening to acoustic music. The DAC direct output can deliver crisper and brighter sound for other genres.
Comparisons with other amps such as the Gremlin and Project Prebox S2 revealed the TA-32's ability to maintain a nuanced and dynamic sound regardless of source or listening material.
Conclusion and Verdict
The xDuoo TA-32 is a highly versatile and capable unit, offering both tube and solid-state amplification options, along with a swappable DAC for customization. Its warm and engaging sound quality shines when paired with appropriate speakers or headphones.
Its flexibility allows it to function effectively as a standalone headphone amplifier, a preamplifier, or a combined solution depending on the user's setup. Its build quality, feature set, and sonic performance justify its premium price point.
While the initial cost is high, the xDuoo TA-32 offers a level of customization and audio fidelity that makes it a strong contender for audiophiles seeking a warm and detailed listening experience. The ability to switch between DAC and tube outputs makes it an incredibly versatile device that can adapt to different listening preferences and system setups.
