An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the power of a signal (a time-varying voltage or current)it is a two-port electronic circuit that uses electric power from a power supply to increase the amplitude of a signal applied to its input terminals, producing a proportionally greater . I've found that some audio amplifiers have sonic signatures so subtle that they emerge only over weeks of listening yet other amps sound so distinctive more vivid, more transparent, more dynamic that their signatures are immediately apparent. Toa electronics, inc is dedicated to the development, manufacturing and distribution of premier commercial audio and security products toa corporation was founded in kobe, japan over 75 years ago.
We often base our judgments about amplifier quality on power output, but there is more to an amplifier besides wattage and power.
