XTZ 100.49???????

Actually the best XTZ speakers are the XTZ 99.26 mkII & 93.23 speakers. I heard them 2 years ago.
There alot like the Wilson Sophia's with a Ribbon tweeter.
They sound great. Plus they look gorgeous in the black gloss.
Here's a pic.

I have not heard the speakers. I own the XTZ CD player, Divine 100, which I purchased direct from the company. I dealt directly with the president who was a super, accommodating person to deal with. Product was sent from China to my apartment. I did all this sight unseen based on a review in Hi Fi World, where the reviewer purchased the review sample. Agree with your assessment that products are well built and use good parts.
