I am listening to the Studio one Pi shipped by Wayne and am very pleased with the sound. I am driving it with low power 300B SE tube amplifier.

I'd like to know, from your experience, how much time is needed for the tweeter to properly run in? The sound improves quite a lot after 20 hours of playing. Should I expect more improvement? How much more run in is recommended?

My second question is, are they made of tight manufacturing tolerances? Do you see the need to match them?

I like the simplicity of the tweeter implementation, and my friends are all impressed with the good clean sound it delivers. Almost forgot, it is so cheap to own.
