Your thoughts: Quad 12L Sonus Faber Concertino

I'm thinking of changing speakers and wanted some input on these. I currently have a pair of Mission 750 limited edition spkrs on 24" stands. I listen to lots of jazz and use a tube front end with a mini Aleph amp. I thank you for your time.
After reading a previous thread on the larger Quads I believe I have my answer. Stay tuned
May the Quad be with you :-)

I don't know about the Sonus.
