That is a good question. One purpose would be to identify some of the best amps available for consideration. What would be even more interesting to me is to identify the best amp you have owned and what three other amps you owned or compared them to; to provide some context and weight to a judgement. It is different to say Amp X is the best amp I heard, and the other amps you are familiar with are Arcam, Rotel, or NAD (nothing wrong with thes, but...) versus having owned/or having worthwhile familiarity with CAT, Atmasphere, or Lamm (or others of that ilk). To some extent, these types of contextualized judgements help assess the strength or relevance of the judgement, a type of listener IQ (don't in anyway mean to sound snobbish about this). Additionally, when anyone says that an amp blows everything out of the water, or incomparable to anything else, I immediately grow weary.
