In Reply to: RE: Correlation between amplifier gain, sensitivity and how it sounds? posted by Mike B. on June 11, 2016 at 16:05:48
I'm running my speakers active and for a while was changing out the individual amps.
At times I had one very sensitive amp (0.5V for full power) mixed with rather less sensitive ones and once the gain is appropriately adjusted there is no audible difference.

Yes. I equate it to a performance car. I own a late model sports car. It has drive by wire throttle control. The factory puts in a program on how fast the throttle works. It is variable by a switch for a couple different modes. The sports mode is a faster ramping up. It makes the car seem more responsive and agile. Same car, same engine.
I eventually removed the sensitive amp because its sound quality was lacking compared to the other amps. It lacked in smoothness, was more noisy and less able to take control of its associated driver.
None of these things I put down to its sensitivity. It was simply not as good an amp as the others.
Thanks guys for the responses.
As I just posted to rkeman above, the amp with the lower sensitivity rating (the more sensitive amp) and high gain does indeed not sound as smooth as the amp with more typical specs. However, in my case the more sensitive amp is a highly rated and very expensive amplifier. I just don't quite like it as well as the other amp in my system. I suspect this may be more about personal preference but I thought I might learn something about correlating specs with sound.
