Max PCM resolution

24-bit/192kHz via S/PDIF-type inputs; 32-bit/384kHz via USB and Ethernet/Roon

Chip or architecture

Discrete noise-shaped PWM, upsampled to 3.125 MHz/32-bit

200 x 110 x 320mm / 7.9 x 4.3 x 12.6 in

THD signal to noise ratio

THD not measurable, estimated at −140dB; SNR 130dB (near theoretical limit for 24-bit files, per manufacturer)
