The EJ-905 you're talking about is a CD player right? I can't seem to find anything on a D-Ej905 or EJ-905, so perhaps you're taking about the D-EJ905? Well, much of the talk about it previously was how it had two 1-bit DACs. In the thread
here, I recently bought the Japanese model D-E900.
It doesn't have dual DACs but it does have great sound and $50 is a great deal...
