3. What's the jitter value?
4. It'd be nice to see how far the FR goes up to for a 88.2kHz PCM encoded to DSD signal to see if there's a digital filter cut-off. This alone may go a long way to explain why you feel SACD "sounds exactly like CD", rather than the actual decimation process.
Thank you very much for your information, this is exactly the reason why I posted this here so that I can correct any mistake I made and to gain new insights.
1. I did not use the digital output, I used the analogue output. And if the Pioneer decreases bit-depth to 20 Bit then a dynamic range of 101 dB is disappointing because 20 Bit theoretically allows 120 dB.
2. I will correct that information, thanks
3. Sadly I don´t know how to calculate it. I simply use Wavelab with a self created -6 dB sine at 11.025 Hz for 44.1 kHz-based samplerates and interpret them visually. As for the amount I took the level of audibility from NwAvGuy who states that -110 dB is a good value. I would think that the jitter value of the BDP-140 for CD playback is as small as 100-200 ps.
4. The frequency range for the measurments files generated by RMAA reaches up to 44.100 Hz, upon conversion to DSD it is reduced to 40.000 Hz, using a gentle low pass. BTW, I used this test signal on SACD also for the Pioneer DV-610 (the review before it) and that player really excels with SACDs regarding sound quality. On analogue playback both exhibit exactly the same aliasing cut-off (or in this case: noise cut-off).
My main goal for my review was that people who might consider using it with analogue connections can make a decision to purchase it or not, purely depending on its sound quality which for CD is excellent. Therefore I ignored digital output from S/PDIF and HDMI.
