IMO they are excellent speakers and the sale is quite a good discount.
I have 10 year old Monitor 11's and they have a great sound. I also have the CC290 center which is also quite good and a great match.
They are doing away with the Monitor line which is the reason for sale...once gone they are gone for good. They have new lines coming which is the reason for the change.
I bought a pair of Atoms to replace my 14 year old Atoms...I have replaced my Monitor 11's with a pair of Prestige 15B bookshelfs and the CC290 with the Prestige 45C center...it is a great upgrade but considerably more expensive, and worth it IMO, than the Monitor line.
This is a retirement gift to me from me...I expect to have and love these for the rest of my life...well until it is upgrade time again hehehe.
The Monitor line has also received great reviews...google to read them or check the links at the Paradigm site.
Good luck and keep us informed...
