Topping DX3 Pro LDAC Version 2 DAC/Amp
LDAC-Equipped for High-Resolution Bluetooth
New from Topping, an industry leader in professional-grade audio equipment, the DX3 Pro LDAC Version 2 DAC/amp is a next-generation audio solution for your desk. Equipped with much of the same hardware that made the original DX3 Pro so popular—an XMOS XU208 USB chip with dual AK4493 DACs, an OPA1612 op amp, and an AK4118 receiver—this version adds LDAC connectivity for high-resolution listening over Bluetooth 5.0. It also packs impressive power for headphone listening: 700mW in each channel at 32 ohms, or 125mW at 300 ohms. Prefer to use a more powerful headphone amp? The DX3 Pro LDAC Version 2 can operate as a DAC via its RCA output. Less than 5 inches long and 2 inches tall, it fits well on most desks.
