Hi Jenny,
As you said in one of your posts, the ideas in your original post were not exactly discussed as much as other things, so I thought I would take a stab at it and throw out some ideas for thought.
Here are my suggestions for some scales that, taken together, might help pin down the characteristics of an audio component. I beleive the scales could be used for any type of component including speakers, amplifiers, wires and cables ....etc. It could be argued that for a given component some of the scales wouldn't apply. That is a reasonable arguement, I made the scales up independent of focusing on a particular component.
Anyway here goes nothing.....
1. Low Frequency Extension describes how low the frequency response goes, as well as how well the bass balances with the rest of the frequency response.
(Lacking / Anemic
Deep / Full)
2. Low Frequency Character describes the accuracy or clarity of the low frequency reproduction.
(Boomy / Indistinct
Tight / Defined)
3. High Frequency Extension describes how high the high frequency response goes, as well as how well the treble balances with the rest of the frequency response.
(Muffled / Dull
Sparkling / Extended)
4. High Frequency Character describes the accuracy or clarity of the high frequency reproduction.
(Harsh / Metallic
Open / Airy)
5. Instrument Timbre describes how accurately the instruments sound or voice is reproduced. How real do the instruments sound?
(Indistinct / Muddled
Accurate / Palpable)
6. Timing describes how clearly all elements of the music are kept in time.
(Dead / Unemotional
Toe Tapping / Engaging)
7. Ambience Reproduction describes how clearly the performance venue sound cues are reproduced (reverberation, echo, background noise etc.)
(Flat / One Dimensional
3D / You Are There)
8. Transient Response describes how well explosive / transient elements are presented (such as snare drum hits).
(Slow / Muted / Rounded
Fast / Pop / Snap)
9. Sound Stage Width describes the over all perception of the width of the sound stage.
(Narrow / Compressed
Wide / Expansive)
10. Sound Stage Depth - describes the over all perception of the depth of the sound stage.
(Flat / One Dimensional
3D / Walk Around The Instruments)
11. Sound Stage Height - describes the over all perception of the height of the sound stage.
(Single Line / Limited
Front Row / Bigger Than Life)
12. Resolution describes how well minute sounds and details are reproduced, especially when they occur at the same time as louder sounds.
(Veiled / Muddy
Detailed / Precise)
From the other discussion that has gone on before, it would be fair to say that any rating will have to be a realitivistic one, specifically relative to the rest of the system the given component is in. However, as was suggested once before, hopefully some common patterns would arrise that helps define certain products.
At the very least it would be nice to have a common ground, common understanding that could be provided by a such a rating system.
