Pacific Valve Great March II
Product Details
The Great March 2 is designed for maximum transparency and is well suited for audiophile quality
high end playback systems. The PCM1798 based Great March 2 Xilinx chip re-clocks the signal and
uses a unique algorithm to preserve the original signal as much as possible. This approach greatly
reduces jitter produced by either the transport or the incoming cable. Next the signal is fed to a TI
SRC4190 sample rate converter to up-sample the signal so the PCM1798 can convert in a more
linear fashion making digital filtering "easy on the ears". This technology makes the Great March 2
No shortcuts were taken in the implementation of the Great March 2. The D/A conversion clock is
totally isolated from the AES/EBU digital audio clocks in a topology that outperforms two-stage PLL
designs. A fully digital de-emphasis circuit supports 44.1, 48, 88.2, 96 and 176.4 kHz sample rates
and is automatically enabled in response to the source signal. A first class band pass filter features
filtering process that does not give a scorching high end with digital grunge. The Great March 2
maybe the smoothest DAC that you may ever hear.
The Great March 2 features Coax, AES/EBU and optical inputs; balanced and RCA outputs. The DAC
uses 2 PCM1798 DACs for conversion and a Xilinx chip for jitter reduction and clocking. The Great
March 2 also features a unique switching circuit that selects the input source on a first come first
serve basis. The Great March 2 has a signal to noise ratio > 96 db and total harmonic distortion of
0.002%
