"The Hi-res USB dac Orpheus is PCM 24bit/192kHz audiophile product, based on Burr -Brown flagship audio DAC with current differential output. Our company has chosen this chip for our new project after multiple auditions together with Bulgarian audiophiles. Passive I/V converter is implemented for best sound. The advantages of the passive I/V conversion are low THD, low phase shift, and low output noises. There are no active components in output section. The passive I/V conversion is realized with high precision resistor and step-up transformer with ratio 1:4, connected in differential mode without common ground point."
