For systems of linear autonomous delay differential equations, we develop a method for studying stability, which consists in constructing an auxiliary system whose asymptotic properties are close to those of the original system. Alongside new signs of stability, we find sharp estimates for the rate at which solutions tend to zero. The effectiveness of the results obtained is illustrated by a number of examples.
