'needed diaphragm control' is not quite accurate.
Panel self-damps quite well due to huge surface area. Not much 'resonance' in that part of the system.......
It would appear that any amp....tube or SS should make 'em work.....
I even used a Kenwood from the 70s for a while with decent results.

Clearly YOU DO NOT GRASP the topic and technology, of my perspective and post.
Big amps and bigger power supplies DO MAKE A DIFFERENCE!!!

You're so wrong about my background.
Owned panels since mid-80s.....MG-1 and later the 1.6qr, which I still have.
Damping factor is about the last thing to worry about with panels. they respond well to TUBE or Sand amps.
they 'store' very little energy...which you can confirm by viewing some reactance data.
A buddy of mine with a pair of 20s uses tubes on the upper end....but DOES, as I'm certain you'd approve, use a big, powerful SS amp on the bottom. with an active crosover.
Please refrain from mindless namecalling.....
While I now have about 250 4ohm watts per panel, I doubt I make use of more than 5 continuous with 50 watt peaks. Low cutting the panelsabout 50hz, buys me a FEW watts, but not a deal breaker....
A minor exception MIGHT be made for the 20 series and I suspect, the 30 series which are PUSH PULL designs with a pole piece on EITHER side of the diaphragm....

There's a clear bass panel resonance and energy storage in my 3.6's at about 42 Hz.
Crickets from Mike.
Not even the basic courtesy to restract his BS name calling.......
And don't forget? Didn't Magnepan originally partner with a tube amp manufacturer when the Tympani came to market? I'd gues mid / early 70s.....
That should answer the 'tubes and Maggies' question.

"And don't forget? Didn't Magnepan originally partner with a tube amp manufacturer when the Tympani came to market? I'd gues mid / early 70s....."
As you know better than I,
those Tympanis were of 8 ohm impedance, extracting less power from an amp. After it was reduced to 4 ohms the same ARC tube amps couldn't fit the bill. (I owned such a 8 ohm Tympani driven by ARC tube amps back in their day.)
good information!
And I guess, after a quick look at the MUG site, that Maggies have been 4 ohm forever after.
At one point, didn't Magnepan use a tube amp on the 'entry' system when you came to visit?
Low poiwer with NO epectations of high levels, though....
Anything in modern tube amps made it MORE possible to run 'em?

I realize that everyone's knowledge and actual "experience" is vastly different. Clearly the case here.
People can only speak up to... the limits of their own knowledge (hopefully backed by experience) When they hit the wall, they become thin skinned, get defensive and (can only) argue.
You and I are done, I will not speak my mind (risk insulting you) I responded with knowledge and direct experience, even gave an image to support my [perspectives] direct experience and current work that I am doing.
Further exchange with or acknowledgement(s) of your post, is unproductive.
Happy Listening.
**I own an ARC VT200, it is not currently being used with Maggies. (I have pictures...)
My Atma-Sphere OTL amps, have never even 'seen' my 3.5rs.
high voltage overreaction imo. you just showed a pic and made a dashed off comment. But in every thread, someone has to pop their head up so the sniper can say you started it. The internet is not a good place to raise kids in.
Those some mighty stuff. I am PROUDLY running my LRS's with my old favorite Audiolab 8000a, still putting out that moderate volume level to beat the band.
I just in that kind of place these days.
I have a VK-500 for when I get the urge to feel like the captain of a nuclear submarine again. But these *are* LRS's, and I have a Martin Logan Depth handling any organ pedals. The LRS alone does a respectable kickdrum. But my volume levels are almost always modest.
Speaking of Modest, I listened to Richter's famous Sophia performance of "Pictures of an Exhibition" for the first time last night. It's a midhall live recording, and my preference is for midhall. The maggies and the audiolab held up their end of the bargain. World shattering performance.
Enjoy

Don't mind another opinion.
It'w when it gets PERONAL that I draw the line.
Enjoy your panels.
My experience is NO LESS valid than yours. Keep that in mind.
And you persist in the high mountain opinion and everyone elses is 'less'......
I'm not suggesting flea power, but DO keep it in perspective. And BETTER watts are BETTER.
I'd like to try a Pass Labs XA30.5 per panel. With it's near-6db headroom? I suspect satisfaction.

Here's a person experince for 'ya.
Owned a PSaudio GCC250 using a pair of the ASP moduels from B&O. 500 each @4ohms. NICE.
But I eventually became dissatisfied with the performance. OH! They ran cool, for sure. And would play loud when asked. But something with the HF began to 'tell'.
I replace it with a PAIR of Parasound A23 of about 200 per channel. And this combination may actually play louder than the PSAudio integrated. Certainnlly more satisfying sound.
Not that it matters?? Parasound makes some weird current claim for these and other HALO amps.
I think that's a red herring. 30 amps would FUSE the output devices. Even at some VERY low voltage, which is the only way I could see that being possible. for 1 or 2 cycles, maybe.
