Luxman 590AXII With Wilson Speakers - which one made the vocals forward?

[Dman777dman777]

When I was at the Hifi shop, I heard the Luxman 590AXII on the Wilson Audio SabrinaX speakers. I loved how forward the vocals were. At first I thought it was the amp that made the vocals so forward. But now I wonder if it was the speakers instead? Anyone familiar with these 2 to know?
