how does current work in an amplifier?


I am trying understand the importance of current in an amplifier.

Quite often, I see that a speaker is said to work best with a high current amplifier.

What does this mean?

How does one determine if an amplifier is or is not high current?

Hi Magfan,

I always wanted a Mac and figured it for good resale if it came to that.

I want the slam without the treble going over the top. Mac seems pretty mellow in that regard, especially if I decide to upgrade to MG 1.7's.

My 1.2's are less than one year old and I can get what I paid for them from my dealer if I trade up within the year.

Understand your comment about doubling power. My thought was the MA6900 or MA7000 at 200wpc or 250wpc.

The other side of this is maybe the panels have to go. I wonder about the new version of the Ohms?!
I hear about few people who have Mac/Maggie. Not to say it wouldn't work or isn't a great combo.....just not 'common'.
Expensive, too, if you go to the MA6900 / MA7000 level.

I had a Rotel RB1070 of 130x2 @8 with NO factory 4ohm rating. That should have been a 'clue'. The amp simply didn't have the guts at higher levels. The Rotel was also 360 'bridged' to which I took to imply 180@4.

When I pulled the trigger on an upgrade I went with nearly 3x the power in a 'd' amp. Even though 'd' amps are time limited at max power, the dynamics are there, which is all that really matters, as far as power goes. IMO.
My local Magnepan dealer demos his speakers with Mac amplifiers. I haven't really listened carefully there for many years, but I don't recall hearing any obvious issues with the pairing. Presumably, the dealer (Shelley's Stereo in Woodland Hills, Ca) doesn't either, since he's paired the brands for quite a while in his showrooms.

If I'm ever up in LaLa Land, I'll be sure to drop in. Woodland hills is a nice place.

I'm way South down the coast in SD. It was where wife and I could afford to buy when we got hitched....back in '86. I love it down here.
Martykl,

There is a Magnepan dealer in Columbus, Ohio who pairs the speakers with McIntosh as well.

The last time I was there, they had 3.6's with something like 400 watt monoblocks. Very real sounding without too much high end in the treble decay.
