So I'm searching to match a 70 db volume.... I have an etymotic er4s with 100 ohm impedance and 100 db per 1 mW. I'm using a fiio e07k with 220 mW@32Ω and, 250 mW@16Ω... I'm using gain of 6 dB (2X) and i'm asuming 2.7 V for the e07k before the gain. So without gain it will 118.62 db max loudness and with gain 124.6434 db...Is this correct? With gain of 6 dB is just multiply 2.7x2=5.4 as new max ouput from the amp? Since the e07k has 60 levels for volume i'm just using proportions to match the desired decibels... but when using equivalents for 70 dB with and without gain it doesn't sound equal... Any help will be apreciated
