    Is there an audible difference in various power amplifiers?

    OK this thread is being sparked by a discussion myself and DBFan187 have had ongoingly. The question is clear.

    I personally believe that the difference is easily detected by human ears.

    quote

    DBFan187:

    OK, a watt is a watt. Amps don't color/warm sound. If yours does, then something is wrong with it EQ's and other processors do, but amps alone don't. An amplifers job is to amplify the signal it recieves. That's it. Nothing else. There is no audible difference between kind of amps.


    Again, my personal opinion, based on years of experience in car audio... there is an audible difference in various amplifiers. I have based this on a comparison between a vacuum tube amplifier and a MOSFET amplifier. They both amplify a signal,true, however, even when both are set at default settings, stripped of all processing and equalization, I can still tell which is which. I can tell the difference, how about you?

    Re: Is there an audible difference in various power amplifiers?

    DBFans statement, I am pretty sure, is based on generalising(sp?) all types of amplifiers as being equal, audially.

    Shouldn't. Thats not to say it cannot be detected. There is no way to have all variables equal between even A/B amps. There is a mechanical difference, so it logically would make an audible difference. Vacuum tube amps, correct me if I'm wrong, have a significantly less power output capability - directly equates to detectable difference in audio. These are not directly controllable variables. They also have a compressed frequency range, and a naturally warmer, boosted midrange characteristic - again an detectable difference in audio output.

    Even with an A/B amplifier, different grades of transistors, output devices, power regulators, etc. all equate to differences in audio output.

    Jmac, do you think you can detect an audible difference between different A/B amplifiers? I can tell a crappy amp when I hear one. All other controllable variables the same, power output, speaker and its load, etc. there is a difference.

    I just want to make the point. Speak up!!

    OK after much reading, and DBFan's convincing...I have changed my opinion. However I still think I can tell a tube and a Class A/B amp apart from one another.

    With the right inline components you can recreate that tube amp sound with a solid state amp.
