How to say "high-end" in Japanese

• 高級こうきゅうJLPT N2approx.Common
  na-adjective, no-adjectiveCovers the broad 'premium' sense: expensive, high-class goods, services and restaurants. Being the common word, it is usually the safest choice when 'high-end' just means luxurious or top quality.
  高級こうきゅうな品物しなものを買かう事ことは、結局けっきょくは損そんにならない。↗

  It pays in the long run to buy goods of high quality.
• ハイエンド
  prenominal modifierLess common than 高級, this loanword covers the market-segment sense: the top tier of a product lineup, especially in technology and audio contexts — top models rather than general luxury.
• 最上位さいじょうい
  no-adjectiveLiterally 'highest-ranking': topmost in a hierarchy or ranking, and in computing the most significant bit. For 'high-end' it is seldom the word you want; it really means the topmost position in an ordered scale.

For 'high-end', use 高級 for premium, high-class quality in general, 「ハイエンド」 for the top tier of a product range, and 最上位 only for the topmost rank in a hierarchy, as with the most significant bit.
