Take for example Israel Blume's Coincident IC's and speaker wire, needing a minimum of 200+ hours break-in and he was correct, of course. It toke every bit of that time to start sounding sweet... Why? Who knows, but it's true. I have never had a single piece of equipment (including wire) that was this resistant to showing its true colors, which are very few (very neutral). Selling expensive Hifi wire is hard enough without this situation and by the way for 299.00USD a first meter for IC's, it is a true bargain. I wonder how many will endure the break-in to glean the results. Count me in as one. Cheers!
