@jamesconroy7030 , nope. ‘Hi-Fi’ stands for ‘high fidelity’. So calling a ‘high fidelity system’ a ‘hi-fi’ is the same kind of abbreviation as calling a ‘polyvinyl chloride record’ a ‘vinyl’. Part of the name is abbreviated and the rest is discarded.

@jamesconroy7030 , no, it doesn’t. ‘Hi Fi’ is an abbreviation of ‘High Fidelity’ and it acts as an adjective in much the same way as ‘vinyl’ is an abbreviation of the full name of the material and acts as an adjective. Alternatively, just like you say ‘Hi Fi refers to the thing itself’ one might say ‘Vinyl refers to the thing itself’ and be equally correct.

Or some pronounce SQL as school.

@jamesconroy7030 , perhaps, but if you’re pedantic about that, also be pedantic about ‘hi-fi’.

@jamesconroy7030 , ‘"Hi Fi" is just another word for a "Stereo"’ – so a stereo Walkman cassette player is a hi fi system? ‘Hi fi’ refers to a quality of sound reproduction while stereo refers to sound source having two channels intended to be played on left and right. Those are separate concepts.

@jamesconroy7030 , earlier you said that ‘"Hi Fi" refers to the thing itself’. Now you’re saying that ‘Walkmans produce High Fidelity sound’. Make up your mind: is Hi Fi ‘the thing itself’ or is it an adjective describing quality of sound? Stop trying to conceal your preference under the guise of being pedantic. You’re not; you’re just choosing to act that way when it’s convenient. With that, I bid you farewell since this thread isn’t going anywhere.

0:30 - Well, actually, we cannot represent all real colours using just three LEDs. There light source produce a triangular gamut which is a slice of all possible colour. There is no set of finite number of LEDs that would allow us to represent all colours.
