From SMSL, the Sanskrit series features compact amps and DACs that are designed to be paired and stacked on top of one another. A powerful discrete headphone amp, the Sanskrit PHA delivers ultra-low noise and plenty of power to drive more demanding headphones. It has an output of up to 545 mW at 64 ohms. Its ideal companion, the Sanskrit Pro-B uses the well-regarded AK4490EQ DAC chip. With both Bluetooth and optical inputs, it’s a versatile DAC with a notably small footprint.
