Audio Engine D1

Little audio engine – It's Audioengine's new D1, a 2nd-gen 32-bit portable DAC/headfi amp with USB-C and Toslink inputs. Inside works an ES9018 converter chip for full-scale 2Vrms output at 4.7Ω. Measuring just 9×7.4×2.2cm, it fits into a pocket. "One of the standout features is its SG2019 USB power filtering, which ensures a clean power supply and noise-free listening experience. It also has an S/R of over 105dB, THD+N of less than 0.0025% and crosstalk of -46dB."
