How much power do I need?

We are asked this question every day. But, individual tastes vary so greatly that a definitive answer is impossible. 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? 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.(And there is no lack of opinions about power in chat rooms on the internet.) 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. 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. 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. Anyone that has a definite answer to this question (without having met you) is probably telling you their personal preference.

65W/channel will probably be on the low side for the Maggies in your size room. If you hear distorted sound then you are probably overdriving the receiver, not the speakers (which could do harm to both the receiver and/or the speakers). In this case moving to a more powerful amplifier (with twice the power) or 3dB more sensitive speakers would likely correct the problem. But keep in mind that if you have a hard floor surface and hard walls that room reflections can cause a harsh or distorted sound as well.

i used a pair of mmg's for 12 years; they'll take all the clean power you can hand them. 65w will be enough in that size room... just don't get carried away with the volume control.

This amp will work at low/moderate volumn but will not do justice to the capabilities of the Maggies. I really don't think that your amp is for the MMG's. IMO.

I've never met a maggie that didn't want more power...
Also, 65 watts at 4 ohms isn't much. Personally I'd want something rated 4 times that-100 watts at 8 ohms is easy to find and usually is 200 at 4 ohms.
