how does current work in an amplifier?

Unsound, There has been testing in the laboratory that has quantified subjective listening objectively. What the testing has shown is that if the sound system violates human perceptual rules, the processing of the music moves from the limbic system to the cerebral cortex. Pretty interesting stuff.

Guys, your knowledge is impressive, but gets confusing for the relative neophyte!

The main takeaways that I got from the last several threads are:

1) do not get hung up on current because Ohms Law demonstrates that current really does not tell the story - if there are watts, then there is current, and vice versa.

2) most music is played at the low end of the watts - rarely does one continuously use much more than 10 or 15 watts.

So.....if I am running a Mac MA6300 integrated at 100 wpc @ 8 ohms and 160 wpc @4 ohms....with the volume control no more than half way....and at this volume level, the meters jump to 100 wpc into 8 ohms just occasionally....but I would like it little bit louder...and I feel that I am missing something.....

Does this mean I am missing the top end of the dynamics due to the amp's powerguard feature kicking in to prevent clipping?

Does this mean that a Mac with more wpc power would give better dynamics (as well as more loudness)?

Or does it mean that the Magnepan 1.2's just lack that last bit of slam because they are not box speakers?

I realize that I am mixing dynamics and loudness here but I think that you can get my drift....

Your continued discussion and feedback, please.

And thanks!

You bring up a good question and I'll be interested to read what others think.

I know that to go louder will start requiring wacky amounts of power. If you go for more power, don't even think of anything less than double+ what you now have.
Also, panels will only go so loud.
You MAY end up moving away from Mac. Sorry, but you are one of the few I've read who make that pairing.
If you can find a Bryston or Pass of similar power, you may find the 'missing slam'.

Atmasphere, all very interesting, and if you could kindly provide a link, I'd very much like to read it. With that said, I'm curious as to who determined, and what are the "perceptual rules", at what point(s) are variances to these "perceptual rules" deemed "violations" and does it really matter at what part of the brain we get our enjoyment? In the end I consistently seem prefer the sound that systems that have speakers that do better with ss amps provide over the alternatives. Obviously I'm not alone.

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?!
