I started to wonder if the filters also need separate break-in? It appears that they soften with use. It's unbelievable that I could have to break in five filters and two analoge sections to get first class sound. My brother the lawyer is probably right when he said, "they should be responsible to sell the unit in operating condition. Someone should sue them!" Now, everybody hates lawyers, but, he sure sounded right.
