It looks like a very versatile piece of gear.
Interesting unit.
As far as I've seen from the product page FRFR is claimed but not proven (no graph provided) 
Is the speaker emulation switchable (I hope so...)?

I have read a bit more into it.
This is a very well tought- out product.
If it is fairly decent (i.e. non-colouring) it could be very successful.

Found it! Only 11.5 kg.
That's great and I'm tempted to try one of these.
It would not hurt

Difficult to tell.
Side by side comparison would be nice.
