An amp is "loud and bright"? Hmmm... Check out the Emotiva site and there are test reports for each model; not sure which model you looked at. I'll just say I disagree. The UPA-200 is 125 W/ch into 8 ohms, 200 W/ch into 4 ohms. It does not have the large capacitors and transformer of a larger amp but if you look inside a class D amp you see even less. But since this thread is about Magnepan's speakers I don't plan to discuss amplifiers -- there's another sub-forum for that.

I am still curious about the ML model you auditioned. I think ML's lowest ESL model is about $2k, closer in price to the Magneplaner 1.7's than the 12's? haven't auditioned recently... I have had ESLs in my system though never owned them, and heard many in other systems over the years. ML makes some fine products, especially in the last decade or so since they solved the panel/woofer transition. Or at least improved it significantly; I still do not think it is as seamless as Maggies. but you do get more bass from the hybrid system. I have always had mixed feelings on their curved panels; they provide a more expansive sound stage at the cost of imaging, greater sensitivity to first reflections, and some loss of efficiency. It has always been a toss-up for me, but I still have my Maggies after over 30 years with them in various flavors (though I admit I have strayed at times).

Yes, they need a good subwoofer. I do like the fact that you can cross over to the sub an octave or two lower than ML crosses over to their woofer; that may be partly why I have always felt Maggies sounded better in the lower midrange and upper bass. The transition in image and soundstage always bugged me a hair with most of the ML models. The little time I have listening to newer ML models tells me it has improved, but still does not match Magnepan's to my ears. YMMV. My current wish list ESL is a Sanders systems, which is also a hybrid system but crosses over to the woofer more than an octave lower than ML's Motion ESL (but performance and price-wise Sanders is closer to the ML Summit, probably a higher-priced product than you auditioned, and the Summit also crosses over much lower than the Motion ESL).

I do wonder a bit about the set-up of the speakers you heard. The specs on the 12's are 45 Hz low end, 1.7's go to 40 Hz, and the comparably priced ML Motion ESL go to 42 Hz, a negligible difference. But, the Maggie's bass is much more sensitive to room placement than ML since the ML crosses over to a conventional woofer at 500 Hz. But you can pick up the 12's and a sub like the Rythmik F12 and have a combination that to my ears will beat the ML Motion ESL for about the same price.

Personally I would not fault either choice, but would make sure it was a real apples-to-apples comparison. That can be tough, unfortunately...

p.s. BDP24 -- Thanks for the kind words! My ears have gotten pretty old, however, alas. As for amps, I had a very early Phase Linear 700 that liked to self-destruct about once a year, taking out whatever speakers were connected if they were not protected.

Hi guys. I would like to upgrade from my current 5.1 setup to a 5.1.4 Atmos system. Currently have:

Front L/R: Magneplanar 1.7s
Center: Magneplanar CC5
Rear L/R: Magneplanar MMG Ws
Sub: Hsu VTF-3
Receiver: NAD t775HD

My concern is that if I am doing some spirited listening I have to push the NAD pretty close to max (20 out of 25).

I like the NAD and would consider upgrading it but apparently they don't have anything Atmos capable yet, and frankly they don't offer the bells and whistles that companies like Denon do (stuff like bluetooth, wifi, apps, etc.).

So I am looking at something like the Denon AVR-X5200W which specs at

Power Output (8 ohm, 20 Hz - 20 kHz, 0.05% 2ch Drive)
140 W
Power Output (6 ohm, 1 kHz, 0.7% 2ch Drive)
175 W

I apologize since I am sure you get these kinds of questions all of the time, but can one of you guys that knows a lot more about this than I do tell me if they think this will drive the Maggies ok? I know I should be looking at better/separate amps and all that but I can't afford that level of performance (OK, actually I'm afraid of what my wife would do to me if I spent that much).

Thanks in advance

The NAD is rated at 4 ohms, the Denon is not, though in the real world that is often of very little consequence. Particularly with Maggies since they do not dip to very low impedances in the normal audio band (some 4-ohm speakers dip to 1 or 2 ohms and are reactive loads; Maggies are pretty flat, mostly resistive, and tail down a bit at very high frequencies). My guess is the Denon would drive them fine but of course it depends somewhat upon how loudly you listen, how far away you are, etc.

Check out an online SPL calculator like the one below to see how much power you might need. A cheap SPL meter is $20 - $30 from Amazon if you want a better idea how loudly you listen.

Worst case you could use the NAD as a power amp to offload some of the channels from the Denon, assuming the NAD has analog inputs and the Denon has preamp outputs.

Wow, thanks for the great reply!

I do have a SPL meter at home, so I will be looking into that as soon as the wife goes to work ;-)

And it had not occurred to me to use the NAD as a power amp. That's a really good idea! The denon does say that it has multi-channel pre out.
