From Avantgarde to a conventional speaker?

I love the coherence and incredible lifelike dynamics and feel to music that I have heard from the Avantgarde Uno and Duo speakers. However, given room size and family harmony, speakers of this size are not going to be a viable option for me. Are there any conventional speakers of reasonable dimension that can compete with the coherence and dynamics of the Avantgarde speakers? I would love to hear from anyone who has made the transition from an Avantgarde speaker to a more conventional design. Many thanks in advance for you help and advise.

All the best,
Neville
