Had the software updated on my pcm3 from 1.41 to 1.44. Dont know if imagining but sound from the bose was a lot better. Is there a connection? Or are updates only for phone connectivity and those types of data connection to pcm improvement?

 

What are the differences between 1.41 and 1.44?

How much did it cost to upgrade?

 

No idea with diff. Free.
