"The DlSCDREAM 2 Ultra features a clamshell design that is ideal for portable devices, reducing potential damage during disc placement. It is made of high-precision CNC-cut all-aviation aluminum alloy, with a carefully polished surface, and a textured finish for a sleek look. The 4.4mm interface provides fully balanced output commonly used in modern HiFi players, delivering 4Vrms/222mW undistorted output power under a 32Ω load, lt can easily drive most in-ear headphones/earbuds as well as high-impedance full-size headphones, including some planar headphones. The 3.5mm interface offers standard stereo output with a 2Vrms output, suitable for driving most in-ear headphones/earbuds. DISCDREAM 2 Ultra is equipped with a powerful balanced/single-ended headphone output and a 3.5mm multifunctional interface that features both a digital optical output and an analog linear output." - MoonDrop
