What are the current useless terms in this "audio world"


Throughout the history of marketing of all kinds of consumer goods there have been many useless, hyperbole phrases and words used.  It seems on ebay, here, craigslist and others a current pet of Sellers is taking something to "the next level"....  which sounds like a great marketing term for an elevator maker.

The worst word in audio is "best," as in "What is the best DAC on the market today?" or "What is the best speaker for under $8k?" or more relevant to your question, "This amplifier [the one for sale] is the best amp I've ever heard."

People should stop using YMMV as it's just a polite way of saying bugger off.  It should go something like, it works for me and I don't care to hear your critiques of what you can't hear in my system.

A few come to mind:

Digital Ready
Quantum (anything)
