On the Bench (JEJ)

At 1 kHz, THD+N for CD was 0.016%, while for SACD, it was 0.017%. In both cases, the distortion is primarily second order.

The results for 19 kHz, 20 kHz combined test frequencies are shown below. There is a visible B-A peak at 1 kHz for CD and SACD at just above 100 dBv.

The measured frequency response for CD was 20 Hz – 20 kHz, -0.2 dB, and for SACD, it was 20 Hz – 30 kHz, -0.50 dB. In the first graph, you can see the slight difference in the high frequency rolloff between Filters 1 and 2.

The jitter spectrum (graphs shown below) for CD mode indicate an average of about 7 ps (picoseconds or trillionths of a second), when a signal was playing, except at the lower end of the spectrum where jitter was up to a level of 50 to 100 ps. Notice that jitter was much higher when using the Toslink output as compared to the coax output. We have shown this same phenomenon with another player, so it is expected that, in general, coax digital outputs will exhibit less jitter than Toslink digital outputs, and you should use coax in your digital connections when possible.
