Tube DIY Asylum

Improved loudness control with digital sources

213.45.222.240

Not so many audiophiles appreciate loudness control (but I do).
The reason why most DIY people do not include loudness control in the volume control of their tube projects is mostly unclear to me.
Anyhow this is the way classical loudness control works.
Most compensation happens at the lowest volume setting but no compensation at all is present at full volume.
Now let's suppose to use a digital source with its own volume control and suitable output level.
By a careful adjustment of both volume controls we can now select the desired SPL and the most appropriate loudness compensation...

If you are in the digital domain just use digital equalization.

  I usually listen to streaming services too but I still prefer analog loudness.
  Digital equalizer is different from analog loudness and analog equalizers.
  Maybe because once you have used for decades loudness control then you become addicted.

In case you prefer an active circuit with unity gain... - cellailuca 08:42:11 07/13/24 (1)
I also recommend a simple loudness circuit (based on 12AT7) thet I designed and built for a small amplifier that I use with my studio headphone.
