Magnepan Owners - Need Your Thoughts Please

Spent some time recently auditioning the Magenpan 12's and 1.6's; I was very impressed with the sound, especially when you consider their modest cost.

I've always had highly sensitive horn speakers so a Magnepan is a totally new direction for me. I will keep my Khorns and consider adding the Magnepans for even more fun! Here are some questions that I need help with. Of course, I will bring them home for a personal in-house listen before I buy but any thoughts that you Maggie owners could add will be greatly appreciated! Questions:

(1)Will a pair of 125 watt VTL monoblocks (EL-34's) be enough juice to drive the Magnepans to reasonable listening levels in my large room (17.5w x 26L x 9h). By reasonable levels I mean 85db - 90db (at the most). I don't want to 'blow-up' the VTL's! They are rated at 130 watts in Tetrode mode into 4 ohms.

(2)I assume that the larger panels of the 1.6's would be harder to drive overall than the smaller 12's?

(3) Setup advice: where do I start on placement? How far from the front wall and how far from the sidewalls? How far apart? Also, are Magnepans designed to be faced straight-ahead or with some toe-in? And, what about the ribbons, placed on the outside or inside?

(4) What are the appropriate listening distances? How far do you sit back from the panels?

Would love to hear Magnepan owners' comments and advice on these questions or any other Maggie issues that I am not thinking about. Thanks!
This is from the Magnepan website:

"We are asked this question every day. But, individual tastes vary so greatly that a definitive answer is impossible. We are using a 35 watt receiver in the lobby to our factory. Therefore, can we honestly say that 35 watts is all you need? For each increase of 3 db, the power must be doubled. So, 70 watts, 140 watts, 280 watts, etc. will progressively result in 3 db increases over the receiver we are using in our lobby. Personal tastes are "all over the map". We hear of customers that are perfectly happy with 25 watts and others using 1000 watts."

I have a pair of MG 12s' that I first used with a Acurus A250 solid state amp, which was 350 wpc at 4ohms. Then I switched to a inexpensive Yaqin MC-100B, which sounded WAY better than the Acurus amp, and that was only 30 wpc in triode mode. Go figure.

I'm now using Cary Slam 100 monoblocks, which are 90wpc in triode mode, and I can't imagine that these speakers could be powered any better. They're dynamic and solid sounding, while accurately presenting sounds that I'm used to hearing live.

As far as bass, I'm a professional bassist, and I have never felt the need for more bass out of these. That said, I completely rebuilt the crossovers according to a tutorial I found online, and now these things are CRAZY sounding. The bass is even more defined, and the detail and depth are amazing. I've also made stands for them that hold them more straight up and down.

I'm done speaker shopping!

As far as placement, I have kids, so I store them out of the way and pull them out when it's time to listen (try doing that with Wilsons :-) I drop them about 4 feet in front of me, in the center of the room, which pretty much takes any room interference out of the equation.

If you like the sound of your VTL's, then I'll bet that you'll like them with the Maggies.
Magenepans like lots of high current power if you want them to play at orchestral levels. Good amps for the 1.6 models would be innersound esl 300, coda, classe 201 etc. The higher powered tube ampes will cost much much more (VTL 450,etc) and are proboably not worth the expense for the smaller and mid sized maggies. You can also try an integrated classe CAP 151 for the 12's and even for the 1.6's or my favorite budget solution; a vintage luxman R117.
I recently bought new MG12's and run them with a McIntosh MA6300 integrated amp. It is solid state at 100 wpc/8 ohms and 160 watts/4 ohms.

My room size is 18 by 33 with 8 foot ceilings.

I have the Maggies sitting on 14 inch square hard wood cubes and in a vertical position.

Due to room logistics and WAF, I have then about four feet from the front wall and about six feet apart. My listening position is about 8 feet out from the speakers so there is about 20 feet of open space behind me. The concrete floors are carpeted. My sense is that the Maggies would sound better if I could use a lttle bit more of the length of the room between me and the front wall.

I play the amp at about 40% of the available gain and am quite happy with the loudness with all types of music.

If you sit and really listen, the Maggies put out quite a bit of bass that has timbre and texture.

Having said that I am thinking about upgrading the low end passover to see if that helps the bass. I already bypassed the fuse and that has improved the high end.

The Magnepan specs show that the 1.6's are a little bit more efficient than the 1.2's.
Well, Stickman, are you ready to try a few tests?

Turn 'em around. Yep....put the mylar to the wall and the pole piece facing you, the listener. Magnepan flipped sides maybe.....15 years ago. I didn't get the memo, so when I went from MG-1 (late '70s vintage) to the 1.6 it took me a while and lots of reading to realize the cause of one of the largest differences between those 2 named panels.
Don't forget there are FOUR (4) ways to orient your panels. Mylar front / back and-or tweeters in/ out.

ALSO, get out the tape. I measure my panels distance to the wall. I use the edge of the tri strip as my reference. I am at 30 1/2" inside and 34" outside.
This is just over a 10degree toe and crosses the speakers about 20 feet away, well in back of me.

To get louder, don't forget relationship between additional power and loudness. Even going to 250 a side, you may not get loud enough.

Dsper? One of the few I've read who use Magnepan with Mac. I'd like to hear such a setup. For me in my room, the MA6900 or MA7000 would be about right.

I always wanted a McIntosh amp since I was in college and finally got the extra coin together to afford one when I turned 57.

I have not listened to anything else with the Maggies and do not know how they might sound with something else.

I think that the Mac quality is there and the protection cicuits work. Before the Maggies, I listened to double stacked Large Advents. While moving the stacks around I managed to cross a wire and the amp protected itself and did not "blow up".

With either the Advents or the Maggies, the amp is dead quiet when it is supposed to be.
