Why not batteries instead of power supplies?


I read about issues with power supplies, like noise from AC outlets, ripples in voltage etc.

Why not just use a large battery that can be recharged? If batteries can power cars, they can for sure power amplifiers.

@erik_squires, "The negative side of battery power supplies is the supplies themselves have inherently high output impedance compared to their AC counterparts, leading to higher cross-talk, and potentially weak bass and dynamic range."

Well, put.  Weak bass and dynamic range definitely plagues the majority of these products.

@whart, "The Veloce lacks for nothing in the areas of bass or dynamics."

Vytas is a buddy of mine, and your point is absolutely correct.  As a basshead and power focused guy in general, he would NEVER build anything that didn't meet that mark, and took a different tack than what I've encountered in many other products.  As we mentioned Erik pointing out, this really shows up as a problem for most other battery powered products
