I have A and D 30Pro stacks. Initially my setup was
OPTION 1
D30Pro=> A30Pro(XLR)
D30Pro=>KEF LS50W(RCA)
-Set D30Pro output to both XLR and RCA(Blanced and Unbalanced)
Being a bit OCD, I prefer D30Pro to have ONLY XLR output, I guess this makes D30Pro signal cleaner without RCA(unbalanced) output. So, what I did is
OPTION 2
D30Pro=> A30Pro(XLR)=>TSR output=>TS to RCA converter=>KEF LS50W(RCA)
-Set D30Pro output to XLR only
-When I use headphones(turning ON A30Pro), my KEF speakers will be disabled
-When I want to use my speaker, I turn OFF A30Pro and the signal from DAC will bypass to KEF speakers.
-No noticeable noise or sounded different from OPTION 1
