I'm using a DCX2496 for the line arrays. Great unit for the money.
You can feed an analog input or AES/EBU digital input. If you have
a SPDIF digital signal, then get a Canare SPDIF to AES/EBU
transformer {~$20}.I'm also using a Roland M1000 for testing.
CD player -> Roland -> DCX2496
I've setup a simple test to see if people can hear five a/d .. d/a conversions vs. the digital path with only one conversion, so far
nobody can identify either pathway.. /lol
