A really nice sharp cibachrome colour print, alongside a digital image on a screen, placed beside a 600 polaroid... they might all be photos of the same thing but they will have totally different qualities. Some of those qualities might be very 'faithful' to the object photographed, some of those qualities may introduce very pronounced artefacts - pixelation, film grain, colour distortion, lower or higher contrast, blur...
Somebody mentioned that warmth is subjective and I suppose that's what I'm reaching for here. I like polaroids but they are not high quality photographic images compared to more 'professional' methods.
So maybe 'warmth' in sonic terms is comparable with visual judgments like 'realistic' or 'nicely lit' or 'pleasingly composed'.
I haven't got a sub-woofer. But I do have my very own subjective-woofer.
