i have LSi9/LSi7 and LSiC speakers system with a AV Sony DA2400ES (85W, 4 ohm). The true is i don´t understand why some people recommend me to buy a amp like a Emotiva UPA-700 (100W, 4 ohm) (the emotiva UPA 500 seems to be unavailable...)

would it be a right choose for listing music and movies? 25 watts of difference, is it enough? do I notary difference?

thanks in advanced

    then, these specs in multichannel mode are theoretical?

    Sony DA2400ES
    (4 ohm 1 kHz, THD 0,7%)
    FRONT: 100 W + 100 W
    CENTER: 100 W
    SURROUND: 100W + 100W
    SUR BACK2: 100W + 100W

    thank you very much

    It's not so much what those specs say....as what they DON'T say. Like all channels driven. Driving 4 ohm speakers with an AVR is pretty much risky business. 9 out of 10 avr's that claim they can drive 4 ohm loads, in reality, is simply engaging a safety to keep the avr from over heating by limiting current. Which 4 ohm speakers thrive on more current. Follow ?

    U jave 30 days to try the amp out.and return it if i think it aint doing it for ya.. might be just enoigh but more power equalls more head room for dynamics. With that said 200 watts and up is what id be looking at
    No idea why people arent saying go with a xpa-5. If u can swing it grab a xpa-2 and use that just for the fronts. Though the xpa-5 is prob all u need as i can just run a.set.of rear.channel speakers off ur current avr as they wont use much power as rears seldom do.

    Lots of people say no home theater should be wothout a xpa-5!

    Will there be much difference between UPA-700 and XPA-5 for my LSi setup?
