The T+A DAC8 is a custom built from the ground up 1-bit converter. I'm not surprised that it would handle native DSD the better than the Yggdrasil which is a 20-bit hybrid resistor ladder / resistor string DAC. The Terminator's claim to fame is being a discrete resistor ladder DAC. Why would DSD sound better on the Terminator than PCM? I am simply not following.
