Just coming back after 10 days out of town. I may have to revise my original estimate of 200-240 hours burn in. I have just done a burn in on new components and a brand spanking new receiver. Receiver has a fully burned-in Furutech fuse. The power cord and speaker cable are well used Audioquest stuff. However, the speaker terminations are NEW Fureutech rhodium spades/bananas. The power cord also has NEW Furutech Rhodium IEC/Male connectors. At about 200-250 hours it was still going up and down with changes. Today, it's at about 420 or so hours. It is calmed down, but I still think the system has a slight hard edge to it. This was the final touches in my mom's system and I had to leave to come home again. lol.
In the end, I think it depends on how much resolution the system has. If you are working with a very warm sounding system, these burn-in exercises may not affect you quite as much. However, with a very revealing system, you could be in for a long term burn-in experience. Though, Rhodium is the way to go if you want the best in resolution.
