High-end amplifier clarification?

If the editors and columnists of TAS or Stereophile refer to the designer of the amp by first name, the amp is high-end. ;)

The amp must have at least one end 3 feet off the floor; this classification method is as accurate as any other you are likely to find. High End is in the ear of the beholder and nowhere else.

Well said.

Pretty well anything found in a "high end" (fancy) audio shop.

How long is a piece of string? I really beleive it comes down to a relativity answer. To some it is a Marantz, to other is its FM Acoustics. I think it is one that is bought at a good stereo store not at Best Buy. One that has a price tag that is just at the crest of your budget.
For me it is "brand X' that is in my system. I omit the brand to avoid the criticism that usually occompanies the mere mention of the brand. Buy what trips your trigger.
