Thinking of upgrading from INNO to Onyx Plus

Looking for thoughts/opinions on any issues you have with the onyx.. I've had the inno for a long time. still works. batteries are still decent, but I dont walk with it anymore, if I listen to xm walking, I'm using the app. But I do see some deals on the onyx and I'm thinking it might be a nice little upgrade, plus it will work on my boombox still.

Do newer radios like the onyx have any sound quality improvements from newer codecs in the hardware? I know it receives the xtra channels.
