Cool. I am getting a CTH amp for review from a kind member.
It is all nonsense. If it were not, one of them, out of so many manufacturers, would produce objective measurements before and after.I've always wondered whether manufacturers exaggerate the effect of break in as a psychological trick.

When I was reviewing the Schiit Yggdrasil I was told it needed to be on overnight to sound right. I measured it before and after and it made no difference whatsoever.
Wow is that the same size as a Schiit Modi?Just got one of these, there is a noticeable improvement in sound quality over my LGV30's DAC. Slightly better separation is the main thing I've noticed, along with slightly more detail retrieval. I wasn't expecting much improvement so I'm pleasantly surprised.
I'm using it with a Massdrop Cavalli Tube Hybrid amp for a very nice setup that cost a bit less than 500 USD. The D50 is also quite small which is nice.

Why would putting a driver in an enclosure make any difference when discussing the driver break-in?Speaker drivers have also been measured to make a difference after some use. However, once put inside of a speaker enclosure, they make next to no difference.
It is the difference between a component and system performance. Two bolts may act differently from each other in a "unit" stress test but make no difference to your comfort when used in the car suspension.Why would putting a driver in an enclosure make any difference when discussing the driver break-in?
Ok, But it is still a rather general assumption, mechanical break-in of drivers depends on different factors, such as material and age. For example, a 50-year-old drive might act differently from a modern one.It is the difference between a component and system performance.

Here is Dr. Toole on this topic from his book:

I saw these measurements while at Harman and the difference was tiny.
It is not an assumption when a major speaker manufacturer actually measures and performs listening tests of the phenomenon. Something that proponents of break-in seemingly are not interested in, or capable of performing the same.ut it is still a rather general assumption, mechanical break-in of drivers depends on different factors, such as material and age.
Not disagreeing with that at all. Just trying to point out there is alot to speaker engineering, and if one is really interested they should seek out the work of Bell Labs/Western Electric and RCA. I would think Dr. Toole would be much more qualified than I, a mere mortal, to explain their importance.It is not an assumption when a major speaker manufacturer actually measures and performs listening tests of the phenomenon.

I think that for headphone drivers break in / burn in is actually effective since there are moving parts. In the recent video from innerfidelity about Mr Speakers they mention that they run the drivers for 24 or 40 hours (can't remember exactly) because after that period they find that there are no significant changes and driver matching can be done correctly. How audible these differences are, i don't know, but i guess that they are measurable.
On the other hand, for amps, dacs and so on, it's just brain break in.
If I can get permission from the owner, I will do a tear down on it.Sorry to keep bringing up the CTH in this thread but thought I'd mention, I came home from work today and powered this thing on... and no sound. The tube is also not glowing anymore.
Would be interested to see a teardown as well to see what kind of build quality / QA they seem to have.
