The term "High End" needs to die. Long live Hi-Fidelity!

AAH...the poets are busy tonight. High Fidelity, High End, Audiophile, and all others are just adjectives to describe what each person wants to identify the subject of sound reproduction. Each of those terms have a different meaning to a lot of people....
If I had almost unlimited funds to spend on a system I would probably do it. If I could buy a new Lamborghini I would do it even the speed limit is only 55mph.
Everybody has their own objective for buying audio equipment. Hopefully, for seeking the setup that sounds best to our ears. But, trying to define terms that describe what audio is, for the most part, is useless.
There can never be any end to this discussion. SUBJECTIVE!

If using scientific instruments to measure things such as distortion, S/N ratio, and a lot of other specs used to present products as superior to others then that's scientific. Sure, a $20K plus system would probably sound better in the same room as one costing $1K. Maybe or maybe not.

I don't think the human ear is capable of discerning minute differences if the main goal is to learn what sounds best to the type of music listened to. Kudos to those who can afford very expensive equipment. But, the question of High End vs High Fidelity has an answer that can't ever be answered.
