I have not heard of Monitor speakers before. Do you have personal experience with them? The AA website is a horrible mess. I use a 22" monitor and can't even see the product because of the huge banner, free shipping bar, search bar, and add to cart bar. There is no place left for product pictures and info. That site is actually worse than the Home Depot website.
Hi Don, I have not heard that model of the MA's. I own 2 older versions of the Silver S1's and they are very good. I have the older S1 and RX1's. I still use both pairs, the former for TV and the latter for my bedroom system. I almost bought a pair of the Monitor Audio Gold 300's but went in a different direction with Arendal 1528 speakers.
MA makes great speakers. What is her listening room like? If it is wood floors and a lot of windows, go with a warmer speaker like the Dali's.
