However, I found that if I listened to an amp for a few weeks and enjoyed it and wanted to keep listening versus being slightly annoyed with an amp and not really enjoying it was more than enough of a test.
The best system makes you hear the music, not the equipment. It can take months for your ears to adjust to the sound of a particular amp. An A/B test will mainly let you recognize what you are used to.
So if it takes months to adjust to the sound of an amplifier the differences can not be that great and it really doesn't matter much which amp you listen to. Is that what you are saying?
If you have ever heard a system that drew you in and made you want to keep listening, keep playing different records, happy and enthralled at the experience, that is a good system. Many systems can sound good, but after a while sounding slightly harsh or strident, a note that stands out, etc. They can be serviceable systems, somewhat exciting, but left off more that they should.
The key is that you are building a system. The amp/speaker/room combination is one where you can take a great amp in one speaker/room combination and have it sound not as good (or even bad) with another combination. You really are not going to know unless you listen to it for a while.
The though of relying on a fast cycle A/B test to tell me what sound I liked better would mean that I lack the capacity to think for myself and enjoy music. It forces choice in an unnatural way.
Sorry but I can't agree with that at all. The fact that I am doing this testing proves that I would rather think for myself and get my own results. If a system is really good it won't take very long to hear it. In no way is relying on what your ears are telling "unnatural". A half an hour or so switching between amps every few minutes with different sources of music would be enough to hear any differences if they exist. The point I am trying to make is saying something like "if the music really pulls you in" is just too generic for a valid comparison of amps.
Let us know when you find the right answer.
Don't know if there is a "right" answer, but there should be at least one answer.
I don't think there's a right answer. The one answer would be that everyone's sense of hearing is different. I think some can process these slight differences and some can't.
Your approach is scientific but you probably need to invite 20 of your audio buddies over and do a blind test for better results.
You are probably right. There are only two possible answers to "does it sound different or doesn't it? "I don't know" to me would mean you can't hear a difference. Now where can I find 20 audio nuts around here?
If an audio system is really playing the music, and you are
playing excellent music, then nearly everyone who enters upon that
scene will be lifted up by it.
It will be obvious to most there that the system is working
musically-- nothing more is needed.
Of course, there will be those who didn't like it-- or maybe
the music. They are the people who will require lots of time
to adjust whatever their own personal diffrugalties happen to be
(they probably can't or won't admit it) -- it isn't about the
equipment or the music..
What was once said about the best among us being the more
adaptable to GOOD change?
Ok guys, so how do you know when the amp is "really playing the music" if not by comparing different amps in real time?
Nothing at all wrong with doing that...
Have at it!
Listen, and share the fun; listen with a few friends. Have them bring a few things to drop in and compare...it is worth the effort...:)
Friend, I would not hurt thee for the world...but thou art standing where I am about to shoot.
My favorite and most reliable friend for keeping me "grounded" is my wife, and she has surprised me several times in the past with her sensitive and discerning listening ability. She could hear no difference between the amps either. So the quest for a plausible explanation continues.
one explanation is distortion on all three amps. post schematics of all three amps with voltages.
I would guess that the odds of the distortion of each of three different amps being of such a nature as make them all sound the same are pretty close to astronomical. I think I have better odds of winning the lottery.
it is actually the most likely scenario. I seem to remember the 813 amp op points were found to be falling off the curve chart. just post the 813 schematic with voltages.
It's good advice, Vinnie!
