I have Monitor Audio Gold 100 bookshelf speakers and absolutely love them, beautiful airy highs from the ribbon tweeters, great midrange and bass so deep and tight I removed my subwoofer from the system. Keep in mind that mine is in a smallish bedroom set-up, though well treated, too. Sound is via a NAD M33, 200 wpc into 4 or 8 ohms. The speakers are 4 ohm and the M33 can drive them to levels well over what anyone would sanely listen too. I was so taken by the MA’s that I bought their silver line 100’s for my living room set-up, both right and left, as well as a center channel. A bigger room might call for floorstanders. They come up occasionally here and on US Audio Mart.
