Something a little different. I got my hands on a ChainTech AV-710 that I briskly modded as much as I could in one sitting
The mods:
1) 3.3V regulator bootstrapped to 5V regulator.
2) Regulator input caps are 220uF Elna Silmic II
3) Regulator output caps are 10uF Tantalum, and 10uF Elna Silmic II bypassed by 1uF Tantalum
4) DAC PSU caps are Nichicon UHE 100uF bypassed by 0.22uF Wima MKP-2
5) DAC Output caps BlackGate NX 47uF/6.3V
Photots:
There is definitely a great improvement over stock in sound quality, and yes, this thing now beats my extreme boutique AlienDAC with BlackGate PSU and AuriCap output! Now I'm already thinking of ordering a pair of 1uF Sonicap Gen 1 to replace those BlackGates
