In that case, the measurements of the preamps would show this huge difference. Can you give those huge, audible difference causing measurements? We are very curious, I am.
Perhaps there is someone here that can comment on a comparison of Rotel’s sound to that of Anthem’s…are they similar? If so, you may be a candidate for new Arcam gear, or similar.
Why should they sound different? Is that the design principle to desigh different sounding component?
By the way, how did you compare those preamps? Any controls for bias?
