It won't work because unless you recalibrate the test is garbage. You can get away with it at -12dB but you can't at -24dB. When doing "Live" tests with Live calibration. -12dB would fail calibration unless you bring input gain up. This test eliminates all these problems and is comparing apples to apples. This compares EQUAL attenuation by Digital vs Analog so the "Listening Level" between each pair would be the same to your ear and the equipment measuring. With prior tests equipment had to be adjusted and may perform differently at different levels. If you did not adjust on prior tests RMAA results are bogus (in my own opinion). In fact the END "listening Level" is the same between all 4 Tests. 98 - 24dB Analog = 76dB 98 - 24dB Digital = 76dB 86 - 12dB Analog = 76dB 86 - 12dB Digital = 76dB http://meridianunplugged.com/downloads/ComparisonAnalogVsDigitalAttenuation/Comparison.htm -- mswlogo XP > Cat5 > Transporter/DuetController > SPDIF > Meridian G68 > DSP6000, DSP5500HC, DSP5000 XP > Cat5 > SB3 > SPDIF > Meridian DSP5000 XP > Cat5 > DuetReceiver > SPDIF > Meridian G91 > DSP5000 'My Transporter Setup' (http://forums.slimdevices.com/showpost.php?p=350741&postcount=45) 'Hitch Hikers Guide to Meridian' (http://www.meridianunplugged.com) ------------------------------------------------------------------------ mswlogo's Profile: http://forums.slimdevices.com/member.php?userid=9090 View this thread: http://forums.slimdevices.com/showthread.php?t=78477 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
