speaker and sub for 300b SET

Hi,

I'm looking for new speakers to run off my Cary 300sei and want something small to bring into my living room. I know you can't have your cake and eat it too with high efficient speakers so I want to add a sub to make up for it. I would actually prefer bookshelf speakers on stands since I'm limited in space and for aesthetic reasons. They will be seated next to my B&W 804 diamonds so I don't want things to look too overwhelming in my living room.

I looked at the popular choices of Omega and Zu. The Super 5 is the only Omega speaker that fits my size but most Zu speakers have small footprints with the Tone being the only bookshelf.

Would love to hear your opinions so let me know what you guys think.
