Wrong assumption, based on nothing.
So, are you saying that Mango player DOES play bit-perfect?
Sure it does. Why do you doubt it?
I know it does, I wasn't doubting that it plays DSD natively. I was making known my doubt of the assumption that Mango was not bit-perfect with the reason why I was doubting it. Maybe that paragraph wasn't too clear with the context.
Anyhow, I installed your "add-on", and really like it. Great job!
