I would take your Q3's over the KEF's. But if you have the speaker itch, I would audition the Raidho D3's (the new & improved version), Wilson Alexia's, Sasha 2's and yes, even the Sonus Faber Stradivari's. Do you have a budget in mind? Those four would be my top picks today....unless you're talking north of $100k.
Of course...you also have YG and Vivid and numerous others.
Based on initial feedback, it sounds like the new & improved Raidho D3 is going to be tough to beat.
What really impressed me was the Franco Serblin Ktema setup (Einstein electronices)...a surprise
