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 LM78/9X “.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))
(Ebay, AC/DC (max. 36V) to 5V-15V Dual Voltage Converter Board Mini Rectifier Power Supply Module, 6€ ->LINK )
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 !! 😉
