    System matching Marantz w/ Tannoys or Wharfedales

    I am trying to match a Marantz SR4001 A/V receiver with either a pair of Tannoy Mercury F1 Custom speakers or a pair of Wharfedale 9.1s. I am not exactly certain how speaker sensitivity, impedance, and other such factors should be evaluated in determining which pair of speakers would be the best match for this particular receiver. I am also considering the Monitor Audio Bronze BR2s, but they are probably going to be outside the speaker budget. Any advice on system matching any of these speakers with this receiver (Marantz SR4001) would be very much appreciated. Thanks in advance to all for your comments/suggestions/replies.

    Happy Holidays!

    Noo Joisey. Youse got a problem wit dat?

    Buy the speakers that you've heard that sound best to you.

    The speakers will determine the sound of your system, not the amplifier. As long as the receiver can handle the load presented by the speakers (impedance and sensitivity), it's contribution to the overall sound is negligible.

    The Tannoy speakers will be easier to drive being nominal 8 ohm speakers vs the Wharfedales and the Monitors being 6 ohm units. Keep in mind that Marantz A-V receiver specs can be misleading. I have the SR5600 and recently learned that just because the spec says 90 watts x 7 into 8 ohms 20hz-20khz, doesn't mean that's what the unit will output. That's based on driving two channels/two speakers. As soon as these receivers go into surround sound mode, Marantz guarantees 70% of the rated power of the unit to each channel. So at 80 watts x 7 in the 4001, in surround mode it's only producing approx 56 watts /channel all channels driven. So I would go with the Tannoys since they are a nominal 8 ohm speaker. I know this for a fact as I recently spoke directly with a representative of Marantz over the telephone. They don't publish this information but I wish they would in the future. The 70% they say is a conservative figure. When looking at A-V receiver specs, always look to see what the rated output will be when ALL channels are being driven. Go with the Tannoys.
