    I'm currently using a Nad C370 120wpc with some Wharfedale speakers that have a maximum power handling of 100w. Does this matter?

    Which Wharfedale speakers are they?

    I don't think you have to worry too much, neither will be exact figures, companies always overexaggerate these figures, my Rotel is only 40W but is comparable in volume to the NAD.

    If you are worried, just don't turn the amp all the way up (like you would!)

    The speakers are diamond 7.1s. Rather cheap. I think the amp is actually rather conservatively rated in terms of power.

    I wouldn't worry too much, the amp will be designed to run with these speakers.

    Might be worth avoiding full volume as they are smallish speakers but I think that would be very very loud anyway.

    You should be able to tell if the speakers begin to struggle but as long as you are careful I don't think it will be a problem at all!

    Hi Smoakes,
    I know your amps rated at 120W but 120W into what?
    Your speakers and amps will say something like 120W into 4ohms 60W into 8ohms.
    Depending on how difficult a load your speakers are for your amps determines how many watts are driving the speakers.
    If for example your amp puts 120W into 4ohms and your speakers are 100W at 8ohms you'll be perfectly fine because your amp is only putting in a maximum of 60W.

    The amp is rated at 120wpc into 8ohms and the wharfedales are 8ohm speakers. They sound fine I just wanted to check.

    I used to run a C370 into Mission 771e and later Quad 11L with no problems.

    The speakers will start to distort long before the amp does, which is a good thing, as amps start to clip, they can damage the drivers

    If you are concerned, just switch "soft clipping" on.
    Alternatively, use the adjustable pre out in an attenuated position which will reduce maximum output of the pre amp and thus have a limmiting effect on the power amps output.

    FWIW, stereophile measured over 1000watts with a single channel driven on the C370!
