Does anyone care to ask an amplifier designer a technical question? My door is open.

@ramtubes I am still a bit hazy on the power versus gain issue. If you increase the gain, are you not increasing the power output of the amp? So what then affects the power output, the speaker impedance only? In that case, how do we ensure that the amplifier is outputting power within the bandwidth where it has the least amount of distortion? As you stated, and can be seen from measurements, typically harmonic distortions start to increase at the upper and lower limits of the design bandwidths (20HZ and 20KHZ for arguments sake) along with increasing power output. |
@4krow I believe most of the Japanese integrated amps have tone controls: Luxman, Accuphase and the newer Yamahas. I am a fan personally, my vintage Kenwood sounds so good. There is definitely something undeniably cool about switches, knobs and levers. All this purist approach is fine and good, but its also boring as hell. |
