A Confused streaming system - Mutec / SOtM Ultra

@Confused I've been thinking about the treble issue. I do not have access to Blades, but I had the Q300 for some years. Similar to the Blade in that it is the 'new' design where KEF avoids amplitude irregularities from the tweeter by shaping the mid-cone. On some material I remember I found the treble a bit 'splashy'. It wasn't too much of it, just a 'colouration' some times. My conclusion at the time was that I was hearing diffraction. Very well controlled and all that, but still. There is a lot of hard surface in front of the tweeter and the treble energy is bound to 'bounce around' a bit. The KEF engineers( Mark Dodd must be mentioned here) have done a heroic job when they created the new Uni-Q driver, but if one looks at other designs with separate tweeters you often find diffraction damping felt around the tweeter cone (a good example here is the Avalon Idea - see the HiFiCritic review). I am not saying this is THE reason, but it may well be part of it in some instances.
