To answer you question below is some key info from Tera player web page. My theory is that the key to the incredible SQ is the choice of R2R DAC combined with his software (proprietary operating system - ASRS technology Charles discusses on his web page).

weight: 80 grams
case: all aluminum black anodized, laser engraved
front rear plates: 2mm aluminum black anodized, CNC machined
main chip: ARM Cortex, proprietary operating system
DAC: NOS Philips R2R with current output, ASRS element and true 16-bit resolution
oversampling: zero -> no oversampling and no digital filter on the Tera-Player
I/V conversion: Burr-Brown
headphone amplifiers: Burr Brown
oscillators: 2 separate ultra-precision crystal oscillators supplied by Golledge with a phase jitter RMS specification of 1 ps (one pico-second) maximum
battery: Motorola LI-ION 700mAh
