Do Audiophiles usually keep the gain of the digital source at around 80%?

My setup is:

A8 Eversolor DAC and streamer

McIntosh C12000 preamp

REL sub 810

Focal Sopra n1 speakers. 

861 Moon amp

I keep my McIntosh preamp usually between 50-60% volume. Any higher would make the sound thin like.

For the Eversolo streamer (which I am enjoying quite a bit for the money), I keep between 75% -85% max gain. With older songs that are recorded at lower volume, I have it at 85%. But with songs that are recorded louders (mostly newer songs) it would cause some/slight clipping at that level so I to have lower the gain to about 75% max gain.  

I saw that there was a max volume throughput option on the Eversolo, but when I try that I can’t really get the system as loud as I want it without clipping and distortion setting in early. 

Is this normal for Audiophiles to keep the gain on the digital signal about 80%?

Wasn’t sure if this should go into digital forums or preamps since both are used here, so I posted here.
