Has anyone heard the new North American products preamp and amp?

In any case, I've learned what I need to know.   I am done with this thread.  Roger thanks for your patience answering questions.   It is much appreciated.  Good luck!

Thanks mapman,

I hope you get a chance down the road to give a listen.
I will be at the Newport Beach show in June.

Roger, just wanted to add that having the upgraded 10X MkIII in the system now for approximataly
three months, have to conclude that the so called sweet spot is not
as critical a sitting position.
In many cases before this acted as a spot light effect. This effect now
is broader like a flood light filling 
the room with music.
I've always addressed room accoustics as being 50% of your 
sounds and consequently now believe that the full potential of my
system has been achieved.

Xaviercg, if what you state is in fact the case, in a way that would belie what Roger has indicated as a reply to my post where I asked if speaker placement even if off in the slightest would adversely effect distortion, etc.

I think you are misinterpreting what both men said.
