How much power do I need?
We are asked this question every day. But, individual tastes vary so greatly that a definitive answer is not possible. We are using a 35 watt receiver in the lobby to our factory. Therefore, can we honestly say that 35 watts is all you need?
You can get a lot of free advice in the chat rooms on the internet. Their power recommendations may be a influenced by their listening habits and room conditions. But, is that of any value to your specific situation? Unfortunately, there is no substitute for your first-hand experience. We also can not accurately advise you for your specific needs. Here is why----
For each increase of 3 db, the power must be doubled. So, 70 watts, 140 watts, 280 watts, etc. will progressively result in 3 db increases over the receiver we are using in our lobby. Personal tastes are "all over the map". We hear of customers that are perfectly happy with 25 watts and others using 1000 watts. Without the option of listening with you, we have no way to give meaningful advice. The most reliable way to answer this question for your particular needs is by visiting a dealer or arranging to hear a pair of Magneplanars. If you listen to your music at your normal volume, in a room that is approximately the same size as your room, with an amplifier similar to what you plan to use, an accurate power requirement can be determined for your listening habits. (Note-- The amplifier used in this test should have a similar 4 ohm rating as the amplifier you plan to use at home, but it is not necessary for it to be identical to your amplifier.)
