Hi Tonton,
Ive been using my Jamo E650 for more than 6 months now and no evident weakness yet. Im a 70%HT and 30% Audio listening and so far my E650 have surpassed my expectations. If youre an HT user, you will never go wrong with a Jamo. The highs are evident, the mids are clear and the bass is fine. Although since i am an HT user, the bass was taken cared of by an M&K MX 125.
Jamo is not popular in this forum as well as in the audio/video industry not because their speaker sucks but because the company does not spend so much on advertising like the others. But i can assure you that you wouldnt go wrong if you will use it in your HT set-up.
Btw, i paired my E650 with a JM Lab Chorus Center powered by a Denon 1604 and the chemistry is quite astounding!
