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

Thank you Xaviercg, Survant, Tbg, for sharing your experience with the Mark III H-cat's! Very Helpful! Very interesting!
Thank You Roger, For you decades of effort, for you amazing products,
For you patience, understanding and wisdom when dealing with...
some folks. You are much better at "child care" than I.
One topic I haven't heard is you wonderful upgrade policy! I am much more comfortable getting something I can upgrade rather than always buying the new version. Thank you for that.
To all of those that enjoy music .
Cheers friends!

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.
