High End jargon; your take

Tight = What you feel when the bartender says, "You don't have to go home, but you can't stay here."

HI Fi = your self congratulatory response when you realize you're the last one there, thinking you won, but couldn't say High Five!

Warm = The feeling you get when being awakened by the neighborhood stray 'cause you couldn't make it into the house the night before.... it's just like being awakened by a horse, except less pressure.

How about this still more ambiguous term?

"Musical" ...as in "it was exceptionally musical."

I'm thinking it's not the sound of pots and pans or cats in heat, unless you're in the Bahamas or the alley passed out again, trying to give the stray with the bladder problem the slip by taking an alternative route.

Or maybe something with Fred Astaire & Ginger Rogers in it.

"Tight" as in "the bass became more tight."

This is determined by system Q - an overdamped, critically damped or underdamped system.

Q of less than 0.5 is tight. (impression is less bass until you turn it up and then it seems like someone is firing a machine gun in the room - think New Order Blue Monday)

Q of .7 is balanced ( a good compromise but still not much bass especially at low levels)

Q of more than 1.1 is muddy and will resonate "warmly" with plenty of bass ( guess what they use in most designs....)

Low Q means low efficiency and high cost.

High Q means high efficiency and low cost (typically a small lightweight woofer with small voice coil in a ported design)

Hi-Fi = High Fidelity which means you are faithful to your wife and buy only small tall narrow speakers that are unobtrusive. Opposite of Hi-Fi is Ja-Bla = Jack-Black where you suffer male menopause and buy a Harley Davidson and get massive speakers in an effort to have a system that sounds as loud as ACDC.

When it's 'tight' you get more pleasure and stimulation.
It also suppose to be 'warm' and 'liquid'

Well I always knew that audiophiles were analytical but this thread seems to have taken a nasty turn.

Tight= Tight bass is bass that you actually hear as well as feel. Bass that is tight is controlled and focused. With tight bass the bass is not just an indistinct rumble. You can actually hear the attack on the bass strings and the detail in the strings. It is not easy to describe. The attack on the strings and the resulting low frequencies maintain a certain coherence. In a series of rapid notes on an electric bass for example, tighter bass means you hear and feel each attack and note distinctly whereas if the bass was not as tight you might not be able to make out the line as clearly and the line would be more of a rumbly blur.

Warm= This means different things depending on the context. Warm can be the opposite of "cold and analytical." This usually means less detail, less neutrality, or less instrument separation but a more pleasing presentation.

Warm also can mean pleasing in the higher frequencies--easy to listen to and not harsh or bright sounding, bright meaning too much treble or shrill sounding. The opposite of warm in this context is not "cold" but rather "fatiguing" or "bright".

hifi - totally nondescriptive although I can see how it might be used to try of explain a sense of higher resolution
