Prodajem novi Audio-GD R-29 - Single Ended R2R DAC Headpone & Preamplifier kupljen prije 20 dana u Magna Hifi, garancija 2 godine. Relay volumen kontrola, pretpojačalo, R2R dac, pojačalo za slušalice.

R-29 is the fully discrete transistors headamp / preamp and R-2R DAC all in one model.

R-29 feature:
1, Fully balance discrete transistors headamp / preampamps and DAC all in one model, the headamp max output power achieve 3800 mW ,no matter to drive most headphones .
2, The unit has two gain modes, the 12DB on low gain for drive the headphone which has over 95DB sensitivity, and 22DB on high gain cooperate with the strong power ability, enough to drive the HE6 which has around 85DB sensitivity headphones. If customer want to boost 6-12DB gain, in total 28-34DB gain.
3, Built in 5 ground linear PSUs and two ground pure class A PSUs
4, Built in 2 group fully discrete real DSD native decoders , and 4 group fully discrete R-2R PCM decoders and 32bit / PCM384K /DSD512 asynchronous transfer Amanero 384 .
5, USB transmit the IIS signal to the FPGA processor and receive the clock signal from the FPGA processor, the USB interface without on board data clocks, the signal transmit is much exact, the sound quality get the much improve .
6, The FPGA process data in the parallel mode.
The IIS data is series transmit mode, every data must need one clock cycle to process or transmit, one frame data ( Include L and R data) must need 64 clock cycle to process or transmit, so the data has effect by the 64 clock cycles.
But the parallel data process and transmit mode only need one clock cycle can finish the one frame data process and transmit, that can avoid the effect of clock stability .
The IIS input (Include USB and HDMI-IIS) has recombine become dual 32bit parallel data once input , and the SPDIF input after decoder, has recombine become dual 24bit parallel data, and the DSD input has recombine become dual 64bit parallel data once input.
The parallel process and transmit mode can improve the sound quality on the transparency and detail but still analog.
