I need help from GMA Europa owners

I'm hoping one of the many Europa owners on this forum can help. After A/B-ing between between Thiel CS1.6's and Europa's, I've decided to keep the Europas -- but I'm having one problem with their sound.

While the Thiels have a remarkable clarity and purity with female voices, the Europas have a slight bit of a haze. The clarity seems to be missing a bit. I'm not sure if it's a bit of distortion, simply the nature of the speakers, or something else.

I'm feeding the speakers from a Musical Fidelity 3.2 CD and Musical Fidelity A308 integrated, through Virtual Dynamics Nite cables. The Europas are sitting atop homemade MDF stands with a sand-filled rectangular center column.

Maybe its the stands, maybe its just the sound of the Europas (they have a soft dome tweeter vs. the Thiel's hard dome). I don't know.

Any insights you Europa owners can offer would be much appreciated. I love the speakers with the exception of the slightly hazy top end. I hoping someone else may have had a similar experience.

Thanks in advance for your help.
