Montana Pbn Xps signature speakers?

Has anyone heard and have an opinion of the Montana pbn xps speakers? . How will they match up with Mcintosh 300w/channel solid state amp?
I've not heard the Montana PBN XPS speakers however they seem to have very good reviews. I own a pair of the Montana EPX speakers that I've enjoyed for 16 years and I would not think of getting rid of them.
I don't know if these are so rare that no one has heard them ,or no one has any opinions.

It's a hit and miss thing. Have to find someone that has the speaker, reads the forum and see's this, and is willing to post.
