The question raised by the OP strikes me as absurd as the answer can be found through self-discovery and the views of others is largely irrelevant. Don't rule out a battery-powered b#tt plug to add to your listening experience, but I suppose everybody is aware of this auditory enhancement. That is my best advice.
What drugs do you use to enhance your listening experience?
In this post let's consider alcohol, nicotine, and coffee drugs, as they are, along with the usual suspects that can get you arrested in most US states and beheaded in Saudi Arabia. I live in Victoria, Canada, which has more marijuana shops than Starbucks, and we have tons of Starbucks. In 10 minutes, I can walk from my house to four dispensaries, which will sell to anyone over 18. OK, enough bragging, For me, a puff, and just one puff (I don't like getting stoned) can be the best tweak ever. A glass of wine is also a fine
compliment. Too much alcohol will increase my enjoyment (because I'm drunk) but put Phil Spector in the room (wall of sound and loss of the stuff I value in my system, such as clarity).
