Ambience, Rhythm, Synergy, Enjoyment instead of PRaT?

Fellow forum members

I have become aware of the importance of PRaT as a means of judging how much enjoyment is gained from a system. I have now come to the conclusion that it may be relevant to post opinions based on the following headings

Ambience - do you feel as if you are in the same room as the musicians? Is the atmosphere of the moment recreated in a lifelike manner?

Rhythm - similar to timing, but is the underlying funk factor present and does the foot tap syndrome become evident? Surely a great test of musicality

Synergy - no point in having the worlds best preamp with a power amp with the control of a wet sock does not make for enjoyment. Components need to be of a similar level of quality - ideally same make because that way each piece of the music reproductive cycle has been built with others in mind - giving synergy leading to more......

Enjoyment - the sine qua non. If no enjoyment, no point, regardless of cost or brand.

I would welcome comments from anyone out there who also feels able to talk ARSE. I know I am not the only one.
