some quick and dirty pics from the DIY-DAC / best sound via Pi4->SkysongXMOS-Bridge->ES9038Q2M (with Burson V5-D)
bought today again some little stuff for the main-goal here on the site->the own „DIY-DAC/network-streamer“ 😉 ..
decided to built it with a separate power supply/-unit (like for example these Mission-PSXs combos (have often posted about it)..(to eliminate any electronical interference/-noise)(the original „combos“ were only for cleaner/stronger „power“)->
and so, i have ordered some dual voltage AC/DC-converter (rectifier), because the manufacturer always say „..best results with a dual 15V-0-15V power source/supply“ (although the chip itself (ES9038Q2M) runs with 3,3V VCC max. (see this Datasheet ES9038Q2M (LINK))..(guess its about the LM78X „.fixed linear voltage regulator integrated circuits“ (i think they took the fixed 15V-version of it)..
anyway, separated today the transformer/power-supply for the ESP32s,oled-display,AK4113 digital receiver etc. to a separate case (in this case also the massive Cyrus-PSX toroidal-transformer (dual 27V) will find his housing))
and okay, as „i fired it up“ with the Pi4 + Volumio and my other XMOS-bridge (Leaf-audio), got problems in detecting it by the Pi, i used then these absolute wonderful Skysong-XMOS-bridge !! (posted also a lot of it before->http://essabre-90xx-rpi.sfb2.com/?p=1883 ) and got these beautiful tune/sound again !! (and its btw. only with these Skysong-bridge (the Leaf-audio (XMOS too) for example sounds lightyears worser)..
got „dynamic-wise“ about minimum 5db 😉 more „frequency-spectrum“ then with my Bluray-HDMI-I2S-extraction-combo (and thats almost the best/optimum combo for this transporter/hdmi/i2s things)..
absolutely fantastic !! (as said „the Pi is made for music“ + these wonderful „best XMOS-implementation“ Skysong-bridge !!)
that was it for now, more to come, many greets and stay tuned !! 😉
