Is the USB output quieter than a the 9v iPower that powers it?

Question: I am interested in measurements of the 5V output of the iUSB3.0 - Is it cleaner than the 9V iPower that powers it?

Answer: Yes, it is cleaner than the iPower because:

  • The iUSB 3.0 Nano and Micro include double-conversion of the power (which actually makes them quite resilient to what power feeds them) and in actual layout, we implement distinct noise barriers between incoming power and signal section.
  • Each output is then fitted with additional passive LC noise filtering and the ANC (Active Noise Cancellation)┬ásystem to remove audio band noise.

The result is very low noise, even lower than the iPower itself. We have internally verified this performance previously using the Audio Precision 2 but the measurements at this level are 'challenging' to say the least and we must delineate for the time being, due to lack of this essential commodity.
