Thanks for that info , then the noise floor on the rest of your hifi is the deciding factor of where you are to apply the volume or combinations thereof . For example with the proper attenuation or gain driving a power amp directly will be trouble free. That may also explain my results as my system is a bit different with another digital volume applied in the speakers given 16 bit sources . Unless I use to much attenuation in the Touch it will be all the same for me I just use less digital attenuation in my speakers I even get the same noise floor , it simply becomes a scaling ( the processor works in floating point anyway then output 24 bit to the speakers . Given that in practice no DAC performs better than ~20-21 bit I will not loose sleep . Btw I tried the practical resolution of my system . -112 dB signals is audible with the ear against a speaker driver and full volume . Much less sitting in the listening position with ambient noise etc can not remember the exact number still at full volume. If don't want to blow of your ears and play extremely loud I'm quite sure not even 16 bit is archived in practice in a home setting unless you have an anechoic chamber test chamber . Doing this test with your typical listening volume will usually result that you can't hear signals -70-80dB down . That is a test signal in isolation not masked by any music it gets totally quiet ! That get us around to the original subject of the tread , how are we supposed to hear all the wonderful improvements below say -130 dB :) they must be there as they are " unmeasurable " according to the cult practitioners as all objectivist fails to find them . -------------------------------------------------------------------- Main hifi: Touch + CIA PS +MeridianG68J MeridianHD621 MeridianG98DH 2 x MeridianDSP5200 MeridianDSP5200HC 2 xMeridianDSP3100 +Rel Stadium 3 sub.
