I agree that sound quality improvements during burn in are not strictly linear. There are multiple regression periods where there is linear, exponential, and stepped improvements as well as plateaus. My experience has shown the improvement model and extent of improvement varied with each piece of equipment. However, I have never experienced periods of negative regression (decreasing SQ). The regression over time was always positive (increasing SQ). I had a previous Krell amplifier recapped by Krell twice. I considered the burn in process normal where SQ improvements began to level off around 300 hours and plateaued at around 500 hours of burn-in. I do not know if you consider that extensive. Remember, that is only my experience with my amplifier and the CAPS from the OEM.
Burning-in as a non-linear experience
I know there has been loads of discussions on the burning-in process of components as well as their parts. If someone does not believe it happens, please do not respond. This is to address mainly the experience people had in burning in components or their parts. The burning-in process is usually described as a linear process, getting from bad to good. But in my experience, and in my system, it is not a linear process. It usually starts from pretty good, to better, then worse, then better, then horrible, and finally wonderful. I was wondering if people had a similar experience. These are pretty drastic changes... And this topic is mainly to focus on this particular thing: non-linear changes during the burning-in process. I had this experience with Furutech NCF outlets, but now I can see the same may apply also to my new capacitors. I have recently replaced my Samsung capacitors with Nichicon LGL2G821MELC40, not an audiophile sort, but the only ones that I could fit in. People are reporting about audiophile capacitors needing a lot of time burning in, I was wondering also if non-audiophile capacities might sometimes need the extended time in a high-resolution system and if their burning-in might also happen not exactly from moving gradually from bad to good.

@mapman - what meds are you on. How is the burn in experience? Please share your findings. LOL Have a great day! |
I have this happen every time I unhook wires or have to mess with the springs under my speakers. It takes a couple days. I have ribbon speaker wires and spades would not stay tight so I had new ends installed. In the mean time, I bought Chinese speaker wire. Silver coated copper with Rhodium coated banana plugs that tighten down and expand the banana once inserted. I had previously tried interconnects of the same wire and liked them. So I purchased the speaker wire. At first I said, detail, crisp, accurate, etc. I have had thse wires for a month. I feel less enthusiastic currently, it sometimes sounds conjested or muffled. I think there has been confirmation bias, burn in, different recordings, volumes, etc. So it can be confusing as to what is going on. I plan to leave this wire for awhile before I put the ribbon wire Beckwith the Rhodium bananas. |
