    I need to know what amps to match up with which speakers. Here is what I have (getting).

    Mains I KNOW what I will match


    SPEAKERS

    B&W 804s--->Marsh a400s(2X200w)



    THIS is where I need the advice

    Center=B&W HTM2

    Rears=601

    Amps

    NAD 214 (2X80w)

    Rotel 976 (3X150w-bridged)



    both amps are about the SAME level (the rotel isn't their top of the line amp, and only cost about $600, while the NAD was around $400, so 1 isn't necessarily better than another, PLUS I really can't hear much difference between them).

    SO, do I (btw, the room is very small)

    Option 1 (Rotel 2X150 bi-amped to HTM2) and (Nad 2X80 to each rear 601)

    use Rotel and BI-AMP the center channel (remember B&Ws are power hungry) with 2 (of the 3) by 150W (possibly a little over kill as far as power goes for a center, but I have always felt you can't have too much power).

    Option 2 (Rotel 2X150 to 2 601 rears) and (Nad 2X80 to bi-amp HTM2)

    is the 80w times 2 in a bi-amp configuration enough for the HTM2? and will the 150w too much for the 601s for the amount (or lack there of) of info to the rear and the lesser quality of the 601 VS the HTM2 (I am not saying they are bad, but certainly NOT the 800 series).

    Option 3 (Rotel 3X150 to all the 3 speakers) and save shelf space

    Although, I like the idea of having different power supplies and seperate amps for more headroom, less crosstalk, etc....

    any advice is appreciated????

    If I were in your shoes, this is what I would do.

    For HT:
    My first hunch says to use the Rotel for all three speakers. But anyways.... I'd first test out the center with the Rotel. See if you can tell a difference going biamped vs. mono using passsages that are demanding, lots of bass content but yet requiring to hear details in the midrange, treble, etc... If the difference is marginal, then I'd go rotel for Center and rears. Of course, if the difference is substantial enough to warrant the biamp, by all means biamp and use the NAD for the rears. I don't think 80W for the rears will be all that bad because surround info isn't as demanding as center channel (center being the MOST important) and Rotel rates their equipment pretty conservatively so the 602's should be fine powered by the NAD. I think the 602's are most sensitive than the CNT too(this is going off memory).

    For multichannel music:
    I'd go Rotel to center + rear simply because the rears are a lot more demanding and play a bigger role in multichannel music than in dvd's on the whole. The playing field is more leveled out between the center and rears with multichannel audio and you should therefore try to supply the rears with good power.
