Does anyone know if Ref.30 has direct throughput for M/C music. It does for 2 channel. It has 5.1 DVD-A in/outs, but I can't set it for 'direct' on menu etc. Also, is DVD-A an anolog signal or is it converted by processor and then outputted as anolog? I have Sony XA777es M/C SACD. Thanks for any help.
