@ian91, I think you are spot on: the MX64 is the bud to own if you are only going to have 1. The more I listen to it, the more I appreciate how perfectly it exposes the violin. If I were studying violin, this would be the bud I’d need. Maybe to 400 does it better? So far this is easily the best I’ve heard and I’m so thankful you recommended it to me!
I'm ever so glad you're enjoying yourself and hopefully for many more hours to come!
I'll be providing a bit more detail on the OFC MX400 STE vs the OFC MX64 STE aPs in an upcoming review.
