    Depending on the speakers you may find it makes a 
difference if heavier wire or shorter leads are used. The 
difference is not in the high frequencies or clearity but in 
the damping at the low end and around the cross-over 
frequency for multi-way speaker. Some speakers may actually 
sound better with some series resistance, some will sound 
best when driven by an essentially constant voltage source. 
Some systems will sound better when connected to the "wrong" 
impedance on the amplifier (assuming it has taps, a lot of 
solid state ones don't).
     Even if you have damaged hearing you can still certain 
kinds of differences.
     My own hearing is odd, I have a deep loss in a broad 
band around 5khz but can still hear 12K or even more. It 
makes it difficult to understand speech especially in the 
presence of noise.
