Most people don't really know what they're listening to anyway so best not to worry about it too much. Besides real audiophiles are constantly breaking in something, probably more than one thing at a time, to be honest, so it kind of comes with the territory. It's an endless cycle of worry and expectation and disappointment. Hence the term audio nervousa. As for reviewers, one wonders if they allow items under test to break in sufficiently prior to review. Maybe yes, maybe no. 😬
