Patrick: I'm interested in what mechanism is involved here that starts to introduce compromises at -30dB which are not present to almost the same extent at slightly lower attenuations. As I understand it, the degree of resolution loss increases proportionally to the amount of attenuation. For example, 24dB loses 4 bits of resolution; 30dB loses 5 bits; 36dB loses 6 bits.
Or are you just saying that, in the context of your own system, you begin to discern some degradation once you get below about -30dB? The maths tells us that if your source material is from CDs, then in an SB/Transporter you need to apply 48dB of digital attenuation before you even begin losing bits that were on the CD to start with. -- cliveb Performers -> dozens of mixers and effects -> clipped/hypercompressed mastering -> you think a few extra ps of jitter matters? ------------------------------------------------------------------------ cliveb's Profile: http://forums.slimdevices.com/member.php?userid=348 View this thread: http://forums.slimdevices.com/showthread.php?t=28133 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
