Consumers suffer from "altered states" of consciousness often, under the effect of marketing...
They believe that changing a good dac for another good one "an upgrade" they will hear more differences in sound than putting a piece of shungite on the dac or a quartz on the connector...Or putting a Shumann generator near one...
I dont believe marketing...
My altered state comes from listening music after i had tuned the room acoustics parameters among others "incredible" feat ( a dude here even doubted that i could tune a bunch of Helmholtz resonator by ears so much ignorant he was in mechanical acoustics and i was able to locate them at the right spot to modify the pressures zone...)
Acoustics experiments are like THC effect : addictive...
And yes i use shungite, quartz, Schumann generators, and Helmholtz resonators, the improvement resulting from that is way over most dac upgrade...
The difference between most good dac on some price level for an average system are minute difference.
By the way no dac sound the same put on different gear and room. More than that they dont sound the same if the system in which they are is treated and controlled or not...
Music alter the consciousness state, it is why music has nothing to do with taste, chose carefully the music you will listen to... Suspend your innate or acquired taste and explore other part of your consciousness...
Learn acoustics and read sound as we read a book...
