Good morning .. ( of to work in a minute ) With 24 bit sources you have a kind of wiggle room anyway so not quite 100 ( I'm again not going to figure the exact math, cue utgg ... ) We have discussed that no practical DAC's are really 24 bit ( more like 19-21 bit on a good day ). That also goes for ADC and other recording equipment assume that the best modern recordings ever made can reach the same level say 19-20 bits ,and that's a wide margin they are probably not that good . Typical recordings don't even challenge the cd system ( most of the recorded history including audiophile favourites like dstm ) , but this is the audiophile forum so assume your best records on your best system :) A guess 80-90 volume is ok for the best recordings ever made ? I have casually assumed that I have a practical 20 bit system at home ( best case quiet day ) and the recordings are at best 16 bit even if branded as 24 bit ( 8 bit of random noise is not going to make it better, even if you bougth them from HD tracks ) . So what gives ? I think I can use some of the Touch volume 70-90 and all of my meridian volume ( properly dithered ) without even theoretically limit my sq . I again I think the gain of the system is of more importance sending a quit signal to the DAC means it closer to its noise floor but preamp or power amp gain if of concern . And I use bits and dB as the same thing ? You can assume that with properly dithered modern equipment . -------------------------------------------------------------------- Main hifi: Touch + CIA PS +MeridianG68J MeridianHD621 MeridianG98DH 2 x MeridianDSP5200 MeridianDSP5200HC 2 xMeridianDSP3100 +Rel Stadium 3 sub.
