Burn in time for a new CD transport?

I definitely heard a difference three hours in which is why the question was asked, have had it on repeat since last night and am getting ready to listen again, I am using the stock power cord maybe that is the burn in I hear. I really wasn't expecting a burn in time though so that did surprise me.

maybe your hearing perception is changing - that is known to occur...

I think it is global warming.

Stop it.

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. 😬
