FAQ
Don’t batteries have the purest DC power?
There is a common misconception that batteries have the purest DC power. The fact is, batteries use a chemical reaction to generate DC power. Each chemical reaction from each type of battery has its own audible noise signature that changes during different phases of the charge/uncharge cycle. The noise signature caused by the chemical reaction differs for each battery, which is why a specific type of battery, such as LIO4, sounds cleaner than another type, such as SLA.
Though better than the inexpensive wall wart type switching power supplies that come with many audio, video, and computer products, batteries can not compare to an ultralow-noise linear power supply in performance.
Ask yourself this question: if battery power has lower noise than high-end linear power supplies, then why are batteries used only in obscure audiophile products but not by the military, aerospace, and telecommunications industries?
