If you have to turn it down by 70 dB (with e70 we will listen to 10 bits at best)), all cats are gray in the dark room)).
Or as an option for this dac - a separate still analog volume control. But I don't really like the idea.
If you’ll have to turn down the volume by 70 dB then you’ve a level mismatch between the DAC and the amplifier or active monitors.
This is not uncommon and one solution is to use passive attenuators or a volume pot.
Here is a post on the RME forum discussing this along with examples of attenuators and volume pot.

>>>Level mismatch is a continuing topic on our forum and support line. The most often reported problem is that active monitors are far too sensitive. The low volume click and pop when turning a unit on/off turns into a quite loud one. A volume control pot then has a very limited operation area, and the master fader in TotalMix has to be lowered to below -20 dB constantly. This also raises concerns about reduced audio resolution. With such a level mismatch hum and noise can also become audible.
What needs to be done in such cases is to make the connected amplifier or speakers/active monitors as insensitive as possible. Ignore whatever the current setting print on the monitor says, choose one that makes them as low in volume as possible.
Some customers encounter situations where this is not enough. We heard of professional and very powerful active monitors using a reference level of +4 dBu, which seems to equal full output power. Setting an RME unit to -10 dBV, which equals +4 dBu at full output level, then again requires to lower TotalMix FX to far more than -20 dB to be able to work at a typical studio listening level - plus having all the above disadvantages/problems.
The solution here is to use passive level attenuation between the RME interface and the amp/active monitor's input by a simple voltage divider, built of 2 (unbalanced) or three (balanced) resistors per channel. Do a Google search for 'line level audio attenuators' or just 'audio attenuators', and you will realize that this is not a RME problem, but a long time classic found everywhere - even in home HiFi. And this is also the reason that the web is not only full of examples on how to build such parts, including the part values and circuit diagrams, but why they are also available at reasonable prices in various models from various manufacturers.
