A load of old coblers? Or maybe not?
I too have never understood what the terms 'fast' and 'slow' mean when ascribed to certain loudspeakers. Nor do I firmly understand what 'rhythm and pace' alludes to. I'm sure that in the minds of some critical listeners they hear something and whatever they hear they ascribe to these adjectives expecting us to comprehend. But it's a secret language that means nothing to me.
Talking in code like this is like visiting the doctor with a UJ infection and using euphemisms to describe parts of your anatomy. He/she can probably guesstimate what you're referring to even if you use the most inventive nouns. But why not use precision (latin or mechanical) words which are completely unambiguous to any professional anywhere on earth and get straight to the point. A standardised lexicon is surely essential to knowledge?
