These are terms used by audiophiles and reviewers when they just wish to describe acoustic perception in terms of light and make a newbie doubt if sound is composed of photons!
So what does one do if a component is bright, warm, shut-in, veiled, cold, sheen, tight, loose, harsh, soft, muddy, grainy, etc (God- adjectives and adverbs from thermodynamics, optics, acoustics and even culinary fields!) This is a crazy world truly and 90% of insanity is bestowed on audio reviewers and few audiophiles (only few?) ! Components describes by reviewers as possessing those attributes are all over the market and people buy them. No where is it said which of these attributes is a virtue and which ones are a vice in a system
This is a perfectly scientific world, our world of audiophilia but once in a while black magic and voodoo suddenly makes an appearance
Even cables, RCA jacks, power supply cords are said to assign tonal qualities the artist or sound engineers did not put into originally. A corollary of this is that, power cords and interconnect act as equalizers. My speakers have a slight peak in the 550-700 hz range. Which cable should is use to tame this hump?
BTW I read somewhere that alcohol makes us more forgiving to distortion. Anyone who has tried it? Maybe a couple of beers would act in switching on the Soft Clipping circuitry we seem to have been wired with but is normally in Off position
I think we just need to listen to the system. If it makes you enjoy music thats the one for you. We would not be heading anywhere understanding the etymology of words used by reviewers nor can we do anything about them. They are paid to write reviews. A good system can make you cry, conjure up memories of a past event or make you jump in the room. Music has made me pick up my racquet and head out to play tennis when I was running temperature. I wonder if a review of an amp or speaker would be interesting if it described the mental state into which the listening session put the reviewer into.
Maybe EEGs, ECGs and pulse rate of reviewer should be published along with the usual impedance-frequency, SPL-frequency and phase-frequency graphs of speakers alongside equipment reviews. I feel they would provide more information about the equipment being tested. What say guys?
