Once again, I like to have another DAC using TDA1541, because all of my previous built TDA1541 DAC already sold like hot cakes.
Same story, I missed it.
Because any DAC using TDA1541 has the magic that always keep me back again, to experience the sound quality from this marvellous DAC IC.
Today DAC build is completely different. I start with multiple power supply for each ICs voltage required, total of them are 5 individual voltages using a toroidal transformer and an EI transformer. Then going to rectifier and filtered using capacitors-resistor-capacitors to passively reduce the voltage ripples. The 10 pieces voltage regulators are used to every voltage required by every ICs pin. The signal from digital receiver to DAC IC are asynchronous re-clocking using external thermal-controlled-oscillator, then the DAC current output is converted to voltage by Pass D1 original design.
The result from this design are marvellous.
