So it's in my main system... A couple comparisons to the Bryston.. Bryston is warmer sounding and more laid back. I'd say the Bryston is still a pretty neutral sounding Dac though. The Nad is not forward sounding either. The Nad makes instruments sound far more real, especially piano. The Nad has less bass, more detail and control than the Bryston. I notice great separation between left and right. Mids are nice. I think you notice more because their is less bass bloom. It doesn't sound thin, but is very different in presentation. The Dac is very fast and captures a ridiculous amount of detail, it's still musical though.
This is just listening to it as a Dac, without the pre function.
