The repair kit is on the way finally. So maybe I can hear them as they should sound. How much power do I need for them so I can have some headroom left for Classical & Jazz? My main amp is a Mac 2505 which is 50 WPC until I get my MC-275 fixed. I was thinking of buying a 150-200 WPC SS amp just for them. Something vintage and inexpensive. Anybody here own a pair or any Maggies? What would be your recommendations? I've had my Valencias longer than my Mac amp so never needed much power as they are pretty efficient.

Their sensitivity is in the mid 80's and power handling is 250 watts. I wouldn't skimp on power 'cause even at 100 watts you're just barely over 100dB.

As Wayne said, sensitivity is mid 80s, but this is at 4 ohms (if memory serves me.) I think 200wpc (clean power at 4 ohms) should be about right, if you really want to rock out.

I have a pair of MMG-W, and they do just fine on a 35 wpc PP tube amp. No, they are not going to bring the house down, but they sound dead-on for small jazz ensambles and uncluttered classical.....Colin

I've a pair of MG-Is as well. Great speakers that introduced me to good audio and ultimately spoiled my taste for mediocre speakers.

The MG-I is rated at 82dB/w/m at 5 ohms input. However, the truly magnaplanar design as these are offer up a nearly resistor flat impedance curve so the 5 ohms is easier to drive tham equivalent sensitivity 8ohm speakers. Depending upon the size of your room, you can get by satisfactorily with that 50wpc amp of yours. I used a cheap 45wpc amp for a few months and found the combination very enjoyable. I've run everything from a 15wpc 6BQ5 Fisher SA-16 amp up to ~200wpc solidstate and found them to sound good regardless. However, this is in an ~15'x16' room (technically larger thanks to an L-shaped design).

If you room is a great deal larger then definitely look for a high-current amplifier more than the watts. Maggies respond more to current than other speakers and you will appreciate the results.

Good luck.

If I may ... here's the MG-I brochure containing some of the technical specifications if you're interested.

Thank you guys for all your input. I was asleep at the wheel and forgot to respond.

I found a Yamaha M-50 @ 120 WPC@ 8 Ohms and supposedly 200 @ 4 )hms so at 5-6 Ohms I should be in there

My room (snicker here ) is my sometimes shop which is 22' X 18'. It's full of stuff and I put a cheap carpet on the floor in front of the speakers and carpet on the wall behind the speakers & gear. It looks a little funky but it knocks down some of the standing waves.

Once again thanks for your input. I got an e-mail saying the kit is on the way so shortly I should hear them as they should sound. I'll order new socks if it turns out well.
