A bit flat, but have to get used to it.

 That setup should sound anything but flat. Can you elaborate on that? Or are you talking about the pizza box shape of the Experts?

Hm.. I think it's quite flat. But in comparison. It sounds balanced. So it's quite a positive thing. Exciting usually means that there are distortions, clipping and harmonics being produced. Now.. its clear, tidy, tight, fast and quiet when it needs to be. I like this. You could say it lacks character, which I would say is the exact thing you want when you pursue close reproduction. 

It's definitely a scale or pizza box with built in heater :-D I hope the molten cheese and salami won't drip its fat.

In the room my setup sits now, it's hard to get a proper sound stage but I know it's not the system; I've had it in better sounding rooms. To combat some of the nasty reflections in this room I can do a lot of acoustic work but until that's done I've found the sound stage can be improved upon by just listening at a lower volume than what I sometimes feel like. Have a go. One thing is for sure, the combo you have doesn't sound flat if the environment is good.
