Black backgrounds and such


So I’ve been reading audio reviews for 25 years but sometimes the descriptions etc used still don’t make sense or I question what they are really trying to say. What is a black background for example?  Is it the silence that exists when my system is off ?  Curious if there is some glossary or explanation or even better an audio recording which would provide examples of one descriptor vs another.  It’s kind of like wine but at least when someone says has notes of blackberry I have a reference point!

I heard it when i upgraded my turntable  - from a Kuzma Reference/Triplanar to the bigger, much heavier Kuzma XL with Airline (lateral tracking) arm. There was less a sense of a turntable spinning-- what i'd call a 'halo' around the sound. Not exactly blacker blacks, but when some source of noise/distortion is suddenly absent, you realize it was there. 
@esthios13- J.G. Holt published a glossary of terms for audio many years ago, I can try to find the link (or someone else can beat me to it), but I don’t remember if he addressed this issue in the glossary.
Hiss may or may not be source related. I use all tubes and play a lot of old records and seldom hear hiss. Some record surfaces are noisier than others though.
N.B. Unbeknownst to me, Holt and/or Stereophile converted his glossary into a book that is for sale. So, I’m not going to look for a link, given that you could buy the book if it is still in print and I’m reluctant to engage in copyright infringement.
It appears that the original book is out of print and crazy money. What appears to be an abbreviated glossary was published online by Stereophile: [url]https://www.stereophile.com/content/sounds-audio-glossary-glossary[/url]
