I read or heard somewhere that many amplifiers do not have enough power to insure good sound quality.... that a speaker rated at less than 95 Sensitivity needed more power to avoid clipping...etc. My own Orsa speakers are rated at 88 db sensitivity...and my NAD C370 has a power rating that is progressive....120 wats and yet it can produce much more...but I don't know how that works. What I am trying to find out is whether an integrated amplifier rated at 250 Watts per channel into 8 ohms would do any harm to my Orsa speakers (88 db sensitivity) or if perhaps it might even improve my sound. The integrated amplifier I have in mind is the Musical Fidelity A-5....which has 250 watts per channel...etc. It also crosses my mind that more wattage in the amplifier might have a good effect on the overall quality of sound produced....anyone dare to tackle that? Bingo
