I would be curious about the source as well. Is it 32-bit, or 24-bit? If you go and change the midi control output to 24-bit, rather than 32-bit, what sort of difference do you hear?
That RWA DAC is listed at a 16-bit, so I guess I'm having trouble understanding how a quality gain could be achieved moving to 32-bits. What does he DAC do when I receives those extra bits, or is it capable of getting those extra bits and subsampling down to 16 bits before he digital to analog conversion?
Maybe Vinnie can interject and educate us.
