I'm in the camp of people that finds them smooth and laidback. In the first 2/3 weeks the sound of the speaker changed drastically for me, so it might change for the better after the 'break-in period'. I use them with an audiolab 6000a amp, the combination is nice to my ears. I'm not familiar with your cambridge amp. And last but not least, we all have a different frame of reference and taste, they just might be 'not your cup of tea'.
