Since she listens to classical, I cannot think of a better integrated for the money than the Blue Circle CS. Nice amp.
Maybe she would get a kick out of the Blue Circle Music Pumps and Music Purse !!

Not familiar with your speaker choice. The Epos M12 are very nice for around $700, or a used pair of the original B&W CDM-1 or maybe the CDM-1NT if you can't find the original (skip the CDM-1SE version).
Also get her a nice used vintage tuner for listening to classical on FM.
