Sound Characteristics:

"Neutral but smoothness sounding ,it doesn't sound skeletal or digital (or metallic). There's meat aplenty on them bones . It's a sigma-delta DAC chip implementation without the dryness, neutrality without the emotional disconnection" - John Darko

The S/PDIF interface uses WM8805 (up to 192KHz) in default. If you want to replace it with the DIR9001 (up to 96KHz) without additional charge, please tell us when you place order.
