This is really easy. I got a bigger improvement by paying an electrician to run a direct line from the breaker box to my listening room (including installing premium PS Audio outlets) than from any other change I've ever made in 40 years of high-end audio.
It cost me $1,200, and the improvement was jaw-dropping. Cleaner, clearer, vast improvement in air and space, tighter bass -- everything you want. The gain was WAY bigger than any other single change I've ever made, and many of those changes cost big multiples of that $1,200.
In many homes, the cost would be even less. It required a complicated run in my house.
If you own your house, just do it!
