and connected to the C1+ via direct connection of I2S bus.
I used a toroidal transformer as a power supply like below picture. The transformer is around $30 in Korea local market.
It works greatly with very high dynamic range (+125dB) and good frequency response.
But the SNR(Signal to Noise Ratio) and THD+N measurement values are worse than the official HiFi-Shield.
It shows around 100dB of SNR while the HiFi-Shield gives over 110dB.

I will upgrade the normal voltage regulators to ultra-low-noise version with some nice capacitors when I have time and money for better sound quality.
BTW, is there any way to use the SRC(Sample Rate Converter) in RuneAudio?
The PCM1794 DAC supports up to 192Khz only while the HiFi-Shield supports up to 384Khz.
I have dozen of nice music files which are recorded at 384 or 352.8Khz.
I couldn't find the settings menu for the SRC. Please help me for my happy Christmas holiday.
