Performance At 48 KHz
Frequency response : The Platinum Pro can always be blamed for having a rather limited level in extreme treble because the drop in quality is noticeable above 15 kHz. With sampling at 48 kHz, it's a case of "could do better"...
Noise level : The result can be described as excellent. As promised, you gain a few decibels in comparison to the Platinum EX.
Motional capacitance : Same as for the signal/noise ration. Excellent, and getting better.
Distortion : Very weak, distortion is similar to the Platinum EX. It's hard to do better.
Intermodulation : Distortion still very slight but it should be remembered that no comparison with previous tests is possible because the measurement method is different.
Diaphony : The values are of the same order as with the previous model, i.e., excellent. The variations may be due to dispersion of features of the components..
