Elberoth2, I repeat, the B&O 500A module is not a complete amp. It will make
no sound if you plug it in.
You are obviously wrong. The 500A module is 100% plug & play. The only thing you need to run it ia a power supply. It is all written in B&O specs in a link I gave you.
My questin still stands though - does H2O modifies in any way the 500A modules they are getting from B&O ?
