Do you have any idea at wich value audible differences usually appears, it's a stupid question I know ? I'm just struggling to get a baseline, what gives for example rising or lowering the volume by 0,1dB or a minuscule 0,5dB change at the treble control -- Mnyb -------------------------------------------------------------------- Main hifi: Touch + CIA PS +MeridianG68J MeridianHD621 MeridianG98DH 2 x MeridianDSP5200 MeridianDSP5200HC 2 xMeridianDSP3100 +Rel Stadium 3 sub.
