  Now, let we take a look, what hides behind the enclosure’s cover

 

PIC. 2  S.M.S.L. DSD PCB Design

    There are 3.3Volt Powered ESS – SABRE9018Q2C Integral DACs, ensuring the Professional Like Studio Top-Quality of 125 dB Dynamic Range! 

   DSD Design involves both the Low-Frequency and High-Frequency Audio Design, where all grounding and all PCB tracks need to be routed with very special understanding and knowing the mattery. Equalizing the differential pairs length is very important. It allows, useful signal to be separated in a great level from eventual phase Noises, reaching the extremely high ratios of Dynamic Range and negligible Crosstalk from the neighbor channel.  

 




  The Symmetry In One Audiophile Design Is As Important As The Usage Of Top-Grade Components!
