Sonnet Morpheus D/A processor Manufacturer's Comment

Manufacturer's Comment

Our heartfelt thanks to Alex for the wonderful review! The measurements of Mr. Atkinson exactly match our measurements. However, we just have a comment on his suspicion that the jitter measurements are the result of the receiver that was used. The J-test is actually a way of determining jitter that is not based on an actual time measurement. The J-test assumes a side effect due to jitter and has more to do with modulation effects caused by jitter. Modulation of that stimulus can only be correct in the presence of a steep digital filter, which is lacking in the Morpheus. If the jitter measurement is performed by means of a real-time measurement, then the result will be around 50ps for both AES/EBU and S/PDIF.—Cees Ruijtenberg
