Bookshelf speaker recommendation

Hi, I’m looking for bookshelf speaker suggestions for my home office. Room is about 14 feet by 15 feet. These will be paired with my Peachtree Audio Nova. Source is computer audio. Listen to classic rock, jam bands, blues, jazz, etc. Looking for a full and rich sound. Well, at least with what you can get from a bookshelf speaker. In this room, listening at moderate sound levels.

Though no doubt not optimal from a sound quality perspective, these speakers will literally be placed in bookshelves. There are corner bookshelves that the prior owner had pre-wired that I am going to use. Shelf height of 13.5”, width of 34” and depth around 25”.
My budget is probably up to $1,500. But I could be willing to stretch for the right speakers. Ideas?
