I don't get the point of this as your essentially just over compensating earlier in the chain for less than optimal gain staging.
Perhaps some users don't really understand the function of the output level knob, thinking that its operating like a MV amp and the sweetest tone comes from cranking it ? If your running into a tube power amp there certainly is a point of where you do want to feed it a robust enough signal, but, more isn't always better.
On my FRFR and monitor desk, I can handle the signal full-on, but then I have to have the monitor level set very, very low. What works better is that I level my patches, then run the output level at about 11 o'clock, which is still a strong signal, as again, I leveled my patches, and I can then have a wide range of control from the monitor output knobs.
