Because we care how our McIntosh stereo equipment looks?

I don't think it's viewed as a temporary hookup. No sense having a cable always protruding from the front of your amp.

Plugs on the front........... ugly. Think MC402, etc. Been toying with the thought of another MA6600. But, as much as I hate to admit it, the MA7900 has a great 'look' to it. Very balanced. Drat. Good thing there is no dealer within 1.5 hours drive.

That's the one new Mac that really interests me.

I'm guessing pagpc was hoping there would be 2 USB with 1 in the front for those occasions when you might want to quickly hook into it for a while. Suppose you could also have a loose cable running out from the back for those occasions.
Agreed that it wouldn't look as nice with such an input on the front, so if there is only one USB, then def keep in the back.

The new MA7900 is a beauty. If you already have a MA6600 adding the new D100 makes for a great combo and brings digital listening to the highest level.

Thanks, but I'm 90% analog so a D100 is likely not in my future, being a luddite and all.
Do like the addition of the MC capability in the MA7900.

I wonder why MA7000 is 250 watts and MA7900 is 200 watts, and MAC/MA6700 is also 200 watts.

It's now merely a decision with what features you require in an integrated.

Shouldn't they be at least 300 watts considering their XR50 is 300 watts RMS?

Well, not so much into integrated these days, but just wondering how they came to that decision.

Would also be interested to see a tube integrated amp, that sounds and looks better than the MA2275, maybe with some tubes showing in front.

The difference b/w the 250w from the MA7000 and 200w on tap w/ the MA7900 is negligible. For a scant 3db increase in volume, which is barely perceptible, you need to double the wattage. ..So the 50 watt difference isn't apt to be noticeable in actual use.

200 watts/channel from the MA7900 and MA6700, into any impedance, is a tremendous amount of power.

A better question, in my opinion, would be: why on earth is the XR50 so inefficient? 81db/1w is about the lowest efficiency speaker I've seen. Still, one won't hear much, if any, difference by driving this speaker with a 200w rather than a 300 watt amp.

Added:
Using a wattage calculator: The difference in maximum output before clipping b/w the MA7000's 250watts and the MA7900's 200watts into the XR50 at 4 meters distance is 1 decibel at clipping. 90db vs 89db. Again, the bigger limiting factor isn't the amps, it's the XR50's very low efficiency.
