Digital Interface had both BNC
and RCA coaxial output but users can connect both at same time.
Uses all audiophile grade components,
including DALE resistors, WIMA & SOLEN caps (German brand), custom order
NOVER (UK brand) caps. Digital Interface applied asynchronous process .
What's different between DSP1 and DSP3:
Both DSP1 and DSP3 are based on the
Altera Cyclone II chip, but we apply different software to perform
different functions. Both have data synchronization to reduce jitter,
but DSP1 has a built-in high performance digital filter, it is only used
for DAC. The DSP3 is especially designed for digital interface only, not
designed especially for DAC. It has built-in upsampling which allows
output up to 96KHz or 192KHz (In default setting, its output is the
original sampling), and designed for high speed SPDIF output, without
digital filter. DSP3 can accept I2S input/output.
What's benefit of the coaxial input:
The coaxial input can improve on SQ
from some low/mid rang coaxial output source. Like some DVD player, PC
sound card, low/mid rang CDP like the Marantz CD67, ect. If the coaxial
output source already quite Hi-end, don't expect the Digital Interface
can improve on SQ.
