How Long Did it Take to Burn In a new piece?


What was the longest time period you ever had to go through when burning/breaking in a new piece of equipment,regardless if was electronics,power cords,speakers,wires,etc.,untill it finally was broken-in and showed its true colors? Would you fellow GON members be willing to share what equipment/timespan you went through this with,and was the transformation gradual or a sudden snap at a specific time? Also,were their certain pieces that never "blossomed" and lived up to your expectations after a lengthy burn-in period,so off they went after your hard work waiting for them to reach their potential.

VSA VR4jr speakers; took about 400-500 to fully break in. I put on some digital cable radio and closed the door to the a/v room for about a month.
My brother bought a bose system 6 years ago and is still waiting for it to break.................in
My Wadia 861 with GNSC's Statement modifications took about 500-600 hours to start sounding consistently good (after the mods). Kept improving through about 1200 hours, then seemed to settle in and now just gives me outstanding tunes.
I have found that speakers take the longest period of break-in time to sound their best. I cannot tell you how many times I have sold a pair of speakers off before they had the chance to settle in. It is because of this that probably the best buys on Audiogon are for speakers that are 3-6 months old. This gives the buyer the benefit of not having to suffer through the break in period with a discounted price to boot.

The speakers that I have had that took the longest to break in were various pairs of Vandersteen speakers. I had a pair of 3A Signatures that did not fully break in until after 6 months of daily play. Once they did the biggest difference from the previous six months was their ability to throw a deep and wide soundstage.
I had a Sony SCD333ES SACD player... took a couple hundred hours to break in. After about 100 hours, the sound quality took a nosedive, then it improved better than ever. In true audiophile spirit, though, I couldn't leave the thing alone. I had it modded, so the unit went through break in all over again. Nice unit, as it turned out.
