Do you understand your amplifier?

Yes!! I understand how my amplifier works
By the way an amp has no sound until it is connected to a speaker and source equipment.Therefore an amp can sound different depending on the speaker mainly and the source equipment

My problem is, my amplifier doesn't understand me!

Who needs to understand it? That takes all the fun out of it. Just enjoy the hell out of it.

I don't understand my amp so much as I think I understand the rational behind it as presented by the maker. Same for my speakers, cables, source, etc.
I also tried to 'match' them as such and I think I did a pretty good job.

LOL @ Dill!
No I don't understand my amp, but as an audiophile I am a rank amateur.
Every time I try to learn about a certain design quality of my amp, like the damping factor or µF memory, someone posts about how that particular design characteristic has no effect on how music sounds. I think there are some electrical engineers on Audiogon who really do understand how their amps' circuitry affects sound, but I'm not one of them.
