だけにPrecisely because; all the more because
だけに presents a result as especially understandable, fitting, or strongly felt because of the preceding quality or circumstance. The result may be favorable or unfavorable.
The reason makes the result especially fitting
The first part does more than supply a cause. Its degree, importance, cost, quality, or history explains why the following result is especially strong or natural. In English, this often corresponds to “precisely because,” “given that,” or an implied “all the more.”
Favorable and unfavorable results
The same pattern works with praise, practical consequences, and disappointment. What matters is that the result clearly follows from the notable circumstance.
彼は現場経験が長いだけに、判断が速く的確だ。
Given his extensive field experience, his decisions are quick and accurate.
AnalyzeHis long experience makes the favorable result especially understandable.
前評判が高かっただけに、実際の内容にはがっかりした。

この作業は複雑なだけに、確認には十分な時間をかけたい。

AnalyzeThe na-adjective takes な before the target.
Why disappointment is common
An unfavorable conclusion is especially natural when the first clause created high expectations. The stronger the expectation, effort, expense, or importance, the more deeply the disappointing result is felt. However, the construction itself is not negative; it works just as well when the outcome meets expectations.
