The Amber 3 along the long burn in time is sounding more full bodied and less "wake up" your system in my opinion. I found the Amber 3 too vivid and "wake up your system" sounding up to some 120 hours. That is now changing and the unit is sounding more and more full bodied and organic. This dac needs time, plus 200 hours, to really hear what she sounds like. This is my belief based on my experience.
If forced to give a final judgement at 120 hours, then I would have said the Amber 3 is just too vivid for me in the presence area for long term listening. Right now, closer to 180 hours, I no longer feel this way based on listening.
So I do not think we are saying different things. Just a matter of timing and burn in realities. I really cannot deal with bright or tipped up midrange and highs.
I also think system synergy is playing a role here. My system has been tweaked and voiced to be full bodied, slightly warm and never forced or forward sounding. The Amber 3 placed in my rig would most likely sound less bright or vivid than in another system that is voiced to be more revealing and detailed.
