    Marantz mono's

    I was wondering what people thought about the marantz MA500 monoblocks. Im considering using one to power my Sonosub and or my Maggie 1.4's.

    Andrew, I have heard good things about the Marantz monoblock amps.
    The MA500 are 125w and the MA700 are 200w. I would go with the 700 if you can (headroom)
    I think Mike Knapp uses 5 MA500's in his system, he might be able to tell you more about them.

      Andrew,
      If the 1.4's that you have are anything like the 1.6's in terms of efficeincy, freq response etc, then the 500's won't do it at all, IMO, and the 700's might. I once tried a pair of 700's in my HT system driving the front 1.6's. They were ok for movies but I didn't particularly like them for music, but your mileage may vary.

          Andrew,
          As far as wattage is concerned, 200W from the 700 series mono's SHOULD be enough, after all I'm driving my front 1.6's with 250W per side with the Bryston 4B-ST. Like I mentiomned in the post above, the 700's were fine for HT use but I felt they were a little too dry and lacked headroom for music, but that may be subjective on my part. If possible, see if you can demo them in your system.

            Isn't it amazing the differences in amplifiers. I would bet that the Marantz probably puts out maybe 300-350 watts into 4 ohms, the Bryston 500 watts into 4 ohms. What startede out as a difference of 50 watts has now blossomed into a 200 watt difference. I hear Maggies are a pretty difficult load, if so it's not surprising that the Brystons sound much better. In fact I would love to have a couple of them in my system to replace a multi channel Classe amp!

              wireless the maggies aren't that difficult really. Yes they are 4 ohm but when you plot that resistance its ery nearly perfectly flat ie its always 4 ohms not fluctuating like normal cone speakers.

                I replaced my multi channel Classe amp with stereo Classe amps. Driving my Apogee speakers it did make a difference.

                  I must be getting my planars mixed up. At 4 ohms then the Marantz would put out 350 watts or so. I think you'll hear a pretty significant improvement over your Denon receiver if you were to go that route. I would definitely go with the 700s though rather than the 500s

                    wireless I'm not using my denon to power my maggies but a HK 5 channel amp. As good as the denon is its not up to the task of powering five 4 ohm speakers.

                      I'm using the Marantz MA700 to drive my Magnepan 1.6QR's and I'm very happy with the results. There rated at 300 Watts when driving a 4 Ohm load.
