There is more snake oil in the audio industry than about any other industry. Why? Because many audiophiles think music is special. When we listen, it engages our emotions and memories. Much of the hearing differences can be attributed to ’the placebo effect’. Research the use of opioids for pain - in blind studies a sugar pill gave as much pain reduction as an opioid pill, if the person believed it to be an opioid. This is what some in the audio industry prey on and use to sell products.
I have no problem with people spending THEIR OWN money. It is theirs, after all. I just use my equipment to enjoy music, whether it be a smart speaker, etc. I just want to enjoy. Too many people spend too much time trying to get it ’perfect’ - there is no such thing.
I say, take a step back, relax, and enjoy!
