Just got a new mini-system: TEAC CR-H100, which is pretty good for the size. I got some KEF Cresta 1 speakers with it. At the moment the bass doesn't seem joined to the rest of the sound and the treble is a bit harsh. (But maybe it's due to the mini system, and the fact they are on top of my TV.) Does anyone know if they change during break in time? B&W speakers do, but i'm not sure about KEFS. Cheers.
