The integrated CSR Bluetooth 4.0 module allows for seamless wireless connection with smartphones, tablets, and computers. It also supports aptX technology, so if your source device is compatible, you can enjoy a more detailed and immersive listening experience. The DT-309B delivers an impressive 30W per channel at 4Ω, making it capable of driving even small bookshelf speakers effectively. It also features a 6.35mm headphone output that works with a wide range of headphones, from 32Ω to 300Ω, giving you flexibility in your listening setup. On the rear panel, there’s a PRE OUT port that can be used as a preamp output, a USB sound card, or even connected to a subwoofer for enhanced bass response. With its versatility, the DT-309B can function as a standalone amplifier, a USB sound card, a preamp, or a full-featured integrated amplifier. Priced above two thousand yuan, it offers excellent value for its rich feature set and superior sound quality.
