Does and don't

I use the furman 20i on my bryston 28 b3 because it has large caps that give it at least 60 amps for transients on loud volumn.they go on sale at 2k.works fine however I would like to plug them directly into the wall but too many power spikes in my area.enjoy the music

Garth was a furman engineered then went to audioquest you can see his interview on  upscale audio website under the niagra power product.worth watching.enjoy the music.
