Lamm being bright or otherwise wrong is a complete nonsense. Another point is match, and yet another point still is personal taste. I think, I understand what the OP wants to accomplish but can't really offer an advice one way or another - Ypsilon or Lamm. How is it possible to decide without comparing side by side or least try one and later another?
I would expect Ypsilon to be lighter and soaring, in a sense, compared to more down to earth Lamm. If I am right, my choice would depend on kind of music that I mostly listened. Some people have two equal but different systems to address just that. Like two tonearms with different cartridges.
The suggestion to pay attention to the source, digital source in this case, is always a good one. But I don't know anything about streamers.
