A little technique...

To illustrate the benefits of our linear power supply, below are two measurements taken "empty" to compare an original FDA power supply to our linear power supply.

The important thing to remember is that one tile represents 50mV.

With the original switching power supply of the AD18 we can clearly see a fairly repetitive train of triangular waves, a large one followed by two smaller ones, this is quite typical of switching power supplies.

From peak to peak we easily reach 80 mV delta which is relatively high.

What you need to know next is that this noise is heard at the output of your speakers and results in a background that is not completely "black", a degraded signal/noise ratio and therefore a loss of detail as well as greater auditory fatigue.

With the ROSE audio power supply, we do not see any switching noise, only very low random noise.

This is a very graphic way to clearly show that a switching power supply is not the best choice for audio applications.
