Well Waldhoerner if you don't have a "broken in" unit to compare to the new and you don't have an A pair and B pair and a cable enhancer like 1953 and you are at the sole discretion of your ears and you have a decent aural memory, assuming you have heard a "broken in" unit it might go something like Supreme Court Justice Harry Blackmun's decision on pornography back in the early 70's, "I can't describe it I just know it when I see it". Well that could be paraphrased to your question something like "I don't know if it's "burned in" yet but will when I hear it". Most of these things are gradual improvements that just become evident over extended listening. Sometimes not at all. Or maybe they do but you really don't notice the change until you can compare it with a new identical item. I have done that and noticed differences at that point. The wishful thinking comes into play when you hope that the amount you spent on the item was worth purchasing it in the first place!
