Hi Danny,

From the description of Rhein Z1 that I posted.  
Since Rhein Z1 used Silent Angel customized OS and does not include Roon OS inside, it does not violate the terms.  
Do you agree with this?

BTW, we are also willing to join the license program of Roon OS.  
Please kindly have contact person response my e-mail and let’s see how to start it.

Thank you!

Best regards,  
Chorus Chuang
