REDT From the New speakers that Iv bought it can very, but within A week of evenings is about right. I love listening to them break in because you can hear them altur over the hours. Enyoy!
Sorry I miss read:stupid: A amp You mean. Iv been up late last night lstening to my MA5100, Just arrived from the USA given as a gift from a fellow AKers. Anyway it still holds the same as my mistake. Lovly to listen to the changes over time.
Surprisingly, seemed it only took 30-40 hours for mine to settle-in. After about 200 hours I swapped out the output tubes and took another 30-40 for them to settle-in with even better sound. This all took place in August.
