I’m the OP of this thread. Congratulations on thinking for yourself and trusting your own ears. You’ve corroborated my own experience that AddPowr’s products are a powerful addition to ANY audio system. I also wrote a follow-up about plugging them into an isolation transformer along with a power conditioner so that every component downstream of the isolation transformer is treated to the same miraculous improvement. My ElectraClears were the original iteration of the technology and your Eau4’s are a doubling of the ElectraClear’s effect, so you did well.
Why this obsession with the seemingly infinite ways to improve one’s system?
Psychologically, I’m creating a private cocoon of aural pleasure that blocks the incessant and irritating intrusion of the outside world. A great sound system is an aural womb, and harkens back to the most perfect and accommodating environment one has ever known- floating in a bath of amniotic fluid. AddPowr’s devices bring you back there.
