[QUOTE="Den123, post: 891205, member: 13454"] ?Plus, he's convinced no amplifier can do anything more than 20khz .... strange character.? :???: Amplifiers extend into the GHz range. We call them RF amplifiers. :) not very good at 20Hz though. Seriously, I had some 300W MOSFET Amps that could go to 100kHz. They melted crossovers if there was something wrong in the system. You couldn?t hear it, but a byproduct of too much (useless) bandwidth. Personally I believe an amp should be close to a DC servo at the bottom end and extend to about 50% above your hearing threshold to ensure it is not ?coloring? the signal. [/QUOTE]
