Pros and cons of R-2R DAC :
1.R-2R will not convert the clock signal into the output signal.
2. R-2R is not sensitive to jitter while Delta-Sigma DA is much more sensitive to jitter.
3. The output signal is much more precise compared to Delta-Sigma DA .
1.THD today is extremely good with Sigma Delta chips; R2R ladders are good too but not as good.
2. Glitches and accuracy of the ladder resistors are very difficult to avoid and require complex technology to resolve it.
R2R 11 CHARACTERISTICS
•R2R-11 are a breakthrough of discrete R-2R designed ladder dac’s. Audio-GD are first in the market offering high performance discrete R2R in this price-range.
•Two pcs DA 8 modules equipped with ultra-high speed CPLD processors to correct the discrete resistor ladder. Unique parallel processing to achieve superb performance .
•Analogue section design based on Audio-GD’s ACSS current driven technology, fully discrete transistors amplifiers.
•Double stages ultra-low noise high speed power supplies offers a musical and black background and favorable transparency .
•Built in Amanero combo 384 USB interface. Amanero offers satisfying and compatibility and marvelous sound quality.
•True NOS design. NOS is less sensitive to jitter and offering neutral sound. To avoid the digital artifacts, a uniquely designed noise rejection processing technology is applied.
•Native DSD support. no switch applied between the DSD and PCM decoder outputs for avoid effect on sound quality but had not obvious switch pop sound appear .
•Built with purity components: all resistors are KOA / Vishay low tolerance resistors , silver tin soldering for all parts on board and ALPS 27 volume potentiometer .
•Option to set Neutral or Warm sound (Jumper setting) according to personal taste.
