I've had good success with Definitive Audio in Bellevue, WA. Ask for Eric Ward if you go there; he knows a lot about Meridian.

If you want to do auditioning, you'd probably want to call ahead. They have several stores; if they know you're coming, they can be set up and ready to go.

They had no problem moving a bunch of equipment around so I could do as close to A/B comparisons as possible when I listened (and watched) various material.
