ABS: What Is The Trouble With Measurements.

The single most significant variable in all of audiophilia is the speaker/room. It is an extremely complicated variable and the only way to understand it is to measure it. The performance variability in electronics is miniscule in comparison. 

The next question is what are you going to do with speaker/room measurements. You have to have continuously variable control of amplitude and delay along with an understanding of acoustics and how to deal with unwanted additions by the room.  

Power to you if you think you can do this by ear. The ear is best at appreciating the results and making adjustments to suite taste. 

I go 100% by listening; I couldn't tell you the measurements of much of anything in my listening chain. That stuff has just never interested me. 

If they're useful to many people, and I know they are, great, but that does not mean they need be useful to everybody.

@larsman I feel the same way about my cholesterol. If I feel good, the numbers don’t matter at all. (Same with my driving speed. Don't consult the odometer...ever! I know what seems right in the circumstances!)

@hilde45 - that's an excellent point, except that nothing in my audio chain can kill me or anybody else if left unchecked. 

@larsman Good point, but I don't think that I need measurements for those things -- my common sense is good enough for them and also for audio. Nothing is at stake because common sense is all I need!
