I did not find the codes for the right commands in the pdf.
Anyhow, I kept the Grace for too long and eventually I had to give it back as it was a demo.
I still have to try the other dac candidate but it looks like if I decide on the Grace, I may have to buy the remote.
Anyhow, Jason, Lyndel, thank you for your help! Much appreciate!
I find this site and the forum very useful.
