At this point in my journey I am beginning to lean more and more towards the source being the supreme component. After investing heavily in my source and streamer I feel like music is more alive, has more vivid colors, and greater sense of flow and atmosphere. A great source almost makes you better understand what the recording engineer and or the players intent is. Albeit, am sure each DAC will attempt to portray their interpretation, but that is something I am noticing more with "hi-end" sources. At least, that's how am feeling for now. I would have never imagined this as I am predisposed to saying go all out on the amp. The analogy I have used before is that if we zoom in on a blurred picture we aren't getting more details. Whatever has already been lost can't quite be recovered with greater amplification. Nevertheless, I have not explored pre-amps, but I am encouraged by some of the findings of fellow headers above.
