Audio Magic Pulsed Electron Alignment AC powered PEA

I have one of these. Price is for one unit. Both are AC power supply powered so no need to keep any eye on the batteries. "How PEAs Work The theory about Pulsed Electron Alignment is based on how electrons spin. They spin either up or down in a phenomenon called spintronics. When there are billions of electrons all spinning their own way, it can create chaos in and around components. By aligning the electrons, you create a more efficient space and eliminate noise. This means that your listening experience is more realistic, with a more musical presentation featuring tighter, more dynamic bass, highs that are delicate and more natural and beautiful midranges. These take your system to a whole new level, and they work for everyone! Our PEAs do not include batteries but do have optional power supplies, so you don't need batteries."
