If you're using the DAC2's XLR outputs -- and if the DAC2 works like the
DAC3 that I'm familiar with -- you can just open the case and move a
couple jumpers to attenuate those outputs by either -10dB or -20dB.

I was always hearing that it is the best to do attenuation at the last

Attenuators between the preamp and the power amp. Have tested different

Actually, I listen to music at
I kind of agree in practise, but I would like to unpack what I see as
the real problem.
There is more benefit than downside with digital VC, if correctly
implemented (low distortion and *dithered*). It's possible with SoX.
There's another requirement, that the attenuation is *moderate*. I'll
There's nothing wrong with digital VC per se, if correctly implemented
(low distortion and dithered). It's possible to meet both requirements
with SoX.
There's a third requirement, that the attenuation is moderate. I'll
discuss this toward the end!
With several popular DACs, the ASRC and
Many up-samplers (including those in many DACs) lack DSP headroom. With
highly dynamically compressed input (read most mainstream music since
90s) the up-sampling creates new samples that should be over 0dB but
aren't.
I think this is one area where people with soundbars, smart phones etc.

Reality Check Time. Agonising over where it's best to apply volume
control is basically a waste of time and effort.
An audio playback system has a fixed amount of gain. It also has a fixed
amount of noise. For any given desired listening level, you need to
reduce the signal level such that the

Or have missed some finer point on how the benchmark works ?
While at it why not look at the whole gain structure. DAC2 is driving
active speakers? A power amp ?
If the sensitivity is adjustable at that end I would make it so the 100%
on DAC2 would represent maximum enjoyable loudness with the
If we are talking two digital volume controls Ill bet the benchmark is
the better implementation and if it has headroom just use one volume
control.
I have an older Meridian pre/pro wo suspect of not having any headroom
for intersample overs , so I upsample and attenuate -3.5 dB in
Squeezelite
In previous discussions I was told that with the Touch anything above 40
with 16 bit source has no rounding errors.
But with 24 bit source any volume reduction will have rounding errors.
The DAC2 has HGC i.e. volume is analogue for analogue inputs but
digitial for digital. The DAC2 also has
Lower the power amp sensitivity. Voltage dvider maybe?

I have a rather high powered amp. If I turn the Benchmark DAC2 to 100%
volume the SB Touch can't play at more than 55. I tend to keep the DAC2
at 50% and that allows me to crank the Touch volume up to 80 (that's
entertainingly loud but not annoyingly loud), but typically more like
72.
