The accuracy of this crystal is very important in how well the DAC will transform the digital signal into analog sounds. Simply put: a better crystal means a better sound! Most SBCs use a very cheap crystal with lots of jitter in order to save costs.\u003c\/p\u003e\n\u003cp\u003eFurthermore, there are 2 kinds of frequencies for digital files: 44.1Khz (wave files) and 48khz (streamed music). Some SBCs (like RPIs) can output only 48Khz, so imagine the degradation of the sound that was recorded at a different frequency.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKali will solve both of those problems\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eFirst, it has a very low jitter NDK crystal feed by LDOs in series for ultra quiet power supply. Second, the FPGA will read the incoming stream, will buffer the DATA 0.7s while discarding the incoming clocks. Using the NDKs it will reclock the buffered data OUTSIDE the fpga (since fpgas introduce about 200ps of jitter) and provide a MCLK\/BCLK that is direct from crystal, providing a jitter-free (almost) to your DAC.\u003c\/p\u003e\n\u003cp\u003eMeanwhile, it will clock the file using the correct crystal (there are 2), fixing the problems outlined in the beginning.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWorks great with Piano\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eKali will not work if your DAC is a master. Dac has to be slave. We highly recommend our Piano 2.1 - they were designed to work perfectly together!\u003c\/p\u003e\n\u003cp\u003eThe million dollar question, how does it sound? Well, the music will \"open up\". The stage will sound bigger, more tri-dimensional. You will hear sounds, words, instruments that were drowned before in a sea of digital mud.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs it worth it?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eDo you enjoy a better wine\/microbrewery beer, or anything will do?
