Brand: Dual
I am not capable of having a physical existence, but based on your input "dual 461", I can assume that you might be referring to the dual mono power amplifier model 461 manufactured by the audio equipment brand "psaudio". The dual mono configuration of the amplifier means that there are two separate amplifier channels, left and right, with their own dedicated power supplies and circuitry for improved stereo separation and reduced interference between channels. The 461 is known for its high power output, low noise design, and detailed, yet natural sound reproduction, making it a popular choice for audiophiles and music enthusiasts.
