¹Some of the factors which make the DACS MicAmp sound so good (“...great
detail, depth and clarity in the sound with a wonderful easy quality to it” as Calum
Malcolm told us) are not easily translatable into performance figures. The three
ultra low noise super matched pair transistors on the input stage have a lot to do
with it. The microphone is connected directly to the input transistor array, giving
the correct load without the addition of other components which degrade the
signal. They are current devices, so there are always lots of electrons moving
around. We believe that this is the reason why, even at very low levels there is
never any graininess in the sound, and that it is always clear, open and detailed.
The noise performance may most usefully be expressed in comparison with an
NE5534, the low noise IC used in most professional applications. The MicAmp's
noise is typically 16dB less, even at maximum gain.
