What is Tight Bass?

I perceive it as articulate bass, the opposite of one note, overly resonant bass. Loose resonant bass is real no no for me, once I hear it in system, can never unhear. Also, recording dependent.

Agreed mostly. I too am a musician (drummer). I never heard a lot of things put forth in the music world which is prevalent among audiophiles. I always took "tight bass" as a bass line that is quick & sharp. I never heard a bass guitar sound that way except on some funk. I was never able to get good bass from the audiophile SS amps. It was a tube amp which showed me proper sounding bass. Yet, I had always heard that SS was better. It is not.

the bass is stronger. maybe more sharp sounding. not sloppy. the opposite of that. clear and with nice resolution.

Here is the short answer, worth every minute of the hour and a half.

Keep in mind that many people prefer the general rumble, as in car radios and juke boxes.  Gives the sound a comfortable cushion and warmth that is pleasing to the ear. 

If you get the bass too tight, the music will sound too lean.
