Discover the Fiio K11 R2R DAC/amp, an affordable entry into R2R technology that delivers warm, detailed sound with a small ...

This approach employs resistor-capacitor-diode and resistor-MOSFET configurations to establish the multi-level negative turn-off voltage and low-impedance branch to suppress positive and negative ...

We read every piece of feedback, and take your input very seriously.

It should feel warm but not extremely hot. Excessive heat could indicate issues like short circuits or insulation damage. As a final test, you can connect a dummy load like a resistor bank to the ...
