ConclusieWhat a tremendous achievement for Sonnet Audio. Where the Morpheus is already a benchmark in the class up to at least 5000 euros, the Pasithea sets the bar even higher. At 5900 euros it is certainly an investment, but in return you get an unprecedented good sounding converter. Measurement wise we do not see any point of improvement and we wonder if we reach the limits of the Prism in certain areas. From a sound technical point of view, we have not yet heard any converter that plays so quietly and in such a controlled manner. Absolutely Alpha Audio Approved!
Measurements and Conclusion
The measurements of the Sonnet Pasithea are…. virtually flawless. We measure THD just below 0.003%, a noise floor that is at and below -160dB. Those are the limits of our Prism dScope we think. Crosstalk ticks the -140dB mark and the dynamic range is 128dB which comes down to almost 22bit if we calculate correctly. Impulse behavior is – not entirely surprising since it is an NOS dac – without any pre- and post-ringing. We can’t find anything that doesn’t add up. Hats off.
