"literally performs almost same as..."
You don't mention the basis for the comparison, whether a specific set of measurements or a subjective determination of sound qualities, but there are a lot of relatively inexpensive DACs on the market that many (but not everyone) love. For example, to mention only two, the Bifrost or Topping D90 DACs are under $1K and widely admired. Meanwhile there are other very pricey products that some have rejected as inadequate, or just overpriced.
Cost alone is rarely the sole factor to consider -- if they wish, a manufacturer could spend ten times more on the case than the electronic parts. Fancy cases make things impressively pretty but add little or nothing to the sound quality. The trick is to listen to something before you buy or decide to keep it.
