What about its internal power supply?

The iDSD Diablo features batteries but also several of our in-house developed solutions in order to have the power feed to key components be as clean and stable as possible. To combat output impedance inconsistencies in batteries, our step-up transformers operate at extremely high frequency. This allows us to use small, low ESR capacitors that filter easily by fully passive means free from any IC regulators. The DAC chips inside the iDSD Diablo are fronted by extremely low-noise regulators and powered by a headphone amp’s pristine power supply. Our Diablo’s own 5V USB line is subjected to multi-stage filtering and specialist ultra-high PSRR regulator, whereas yet another of the same type regulates voltage for the product’s internal CPU.
