I am looking for a good amp to power up either the 1.7 or 3.7 magnepans. The room size is 18x21 12 foot ceiling . I have been looking at the rogue Audio equipment since I have dealer close.The atlas amp with the Rp1 pre amp or the m-180 mono block with the Rp1 .Does anyone have any experience with the rouges? Any advise would be appreciated

I cannot speak for the Rogue amps you mention, but my experience has
been nothing but positive.

Magnepans do VERY well with tube amps.

Maggies require a LOT of power; it's almost impossible to provide
too much power; and providing them with adequate power from a tube amp
can get very expensive. You have a big room, so you're going to need
a LOT of amplifier power.

A lot of people utilize a tube preamp and a solid state power amp as a
cost effective alternative. I've no experience with high quality ss
amps, but there are the usual suspects: Ayre, Pass, Boulder, Rowland,
Bryston, and many others. A rogue preamp and the latest Bryston
4B-series amplifier should provide adequate amplification.

Do NOT underpower your maggies. You will regret it.

Good luck. I recommend the 3.7s over the 1.7s for a room your size.

I think you will like what you hear.

I would try posting this on "planar" asylum, as they would have more information specific to your speakers.

Here are a few off the top of my head in no particular order.

1) Pass Labs.....X250, X350,
2) Parasound Halo.....A21, JC1
3) Bryston......4bsst and all its iterations
4) Adcom......GFA-555,5500,5802
5) Classe.......Any of them
6) McIntosh......MC-402, MC-602, or the big monos.
7) Sanders.......Magtech
8) SimAudio
9) Kell......KSA
10) Oddessy..... Khartago

You can drive Maggie's with tubes with great results as well. Just make sure to use at least 40 watts per channel with more being better. I liked KT-88/6550 amps but that's me. I have heard BAT gear on Maggie's and was impressed as well.



Stay calm and return fire.

Magnepans speakers from SMGA to MG-IIB in the past. I agree with what everyone said. They do require lots of power but not just brute power mind you but power with finesse and very stable that can withstand an impedance all the way down to 2 ohms.

The best power amp that I used to drive my Maggie MG-IIB was the Audio Research D-250 tube amp that put out 250/w at 8 ohms. It sounded very open and smooth with silky top end coupled with articulated bass.

For some arcane reason the menu at the top of the page does not include the "Planars/Statics/Ribbons" listing.
The listing can only be found 2/3 of the way down the front, vertical menu.
Here is a link anyway..

...a very knowledgeable poster here who passed away a few years ago used Gilmore Raptors very successfully with his Maggies.

I heard them and they sounded great.

I also used and liked the Gilmores on my 3.6's I now use a pair of Berning ZH270. But to answer your question you will like the Rogues on Maggies. The monoblocks should be very good. Very nice sounding amps.

The locally produced Clayton amp I once heard on a pair of 2.7QRs has been the best amp I have tried on Maggies. Who in the "Lou" has Rogue Audio? Nice to hear someone that remembers Flips. I got my first tube amp there many years ago.

The 180 watts from the Rogue mono blocks will sound very, very good
The lots and lots of power crowd overstates there case. I have driven my 3.6's with 80 watts and they sounded terrific

I tried to run a rebuilt HK Cit-II tube amp at 60 wpc with a pair of Maggie 1.7's, but Merlin TSM BME Monitors just sounded better with that amp (sold the Maggies). I like Maggies and some day may try a pair of the new Maggie 1.7i's, but it will be with a SS Amp at 150+ per channel. I'm not an expert on Maggies, but I've always heard they like power to sound good - - - if not exceptional. I don't know the current pricing of the 1.7i's, but at around $2K they are a heck of a speaker with the right amp. As the Tool Man would say, MORE POWER! Just an opinion.

You need at least 100 wpc with a big power supply
With my 2 bernings I am running effectively 200wpc and can blow myself out of the room

I am getting so many different opinions .I just want something that's going to sound very good in that room.I have been told the 1.7 would would work with the rouge atlas and rp1 pre amp but might not be big enough for the room if I I listened at louder volumes.I also been told that the 3.7 are a better choice for the room but then the question becomes if the 100 watt atlas separates will be up to the challenge.I have mentioned the rouge mono m-180 mono blocks 180 watt per channel a few times with the rp1 but a lot of people are not familiar with them.I have a rouge dealer not to far from me, but could always have something shipped to me.Magtech has been mentioned along with Heger but I don't know much about them.I guess I am old school something that weighs 50 pounds that puts out 900 watts boggles my mind.

In my experience even 100wpc of power might be marginal on Maggie 1.7's. I say this because I brought my 100wpc Rogue Stereo 90 Magnum amp (KT120 x 4)to a friends house and put it on his Maggie 1.7's. It was OK but a little compressed sounding whereas his 300wpc SS monoblocks sounded great. On the other hand my Rogue amp did very nicely on my Thiel speakers.

I have heard of guys running one Cit II per channel on the Maggies and other difficult loads. It works well since if you have a couple of my "McShaned" (as Mikey Samra calls them) amps you get about 120-130 watts RMS per channel and about 150-175 watts per channel peak. That's more like it...

But one amp usually comes up a bit short on power.

I think the answer depends on room size, listening habits and wether you have the 1.7 or 3.7. I can tell you that in a medium sized room playing orchestra music at high spl the 1.7 does significantly better with 1000 w Bryston monos vs their 500 wpc stereo little brother. Transient impact I would call it.

I am of the opinion that while quality matters, you can't have too much juice wth these panels.

I don't recall the brand / model of the 300wpc amps but I do remember that they were tiny upmarket (not cheap) Class D monoblocks.... and I'm not generally a fan of Class D.

In this case it certainly appeared that the 100wpc Rogue tube amp was under powered while the monoblocks were more than sufficient. It wasn't a matter of room size or volume level. The 100wpc tube amp simply sounded slightly 'compressed' on the Maggie 1.7's regardless of volume level.

This same Rogue amp is hugely dynamic and robustly powerful on other speakers that are easier to drive including my Thiel CS2.4 (which aren't the easiest but nothing like the Maggies) and my Tannoy Definition D500's. I no longer have the Rogue Stereo 90 Super Magnum amp. I have the similar Rogue Cronus Magnum Integrated that puts out about 100wpc using KT120 power tubes. The larger Rogue monoblocks might work.

You can visit 10Audio.com. I live a few miles from JerryS (the reviewer) and you'll probably find those Class D monoblocks in his review listing. They weren't W4S or any of the 'value brands'. They were very expensive as I recall ~$8000 - $12,000 range.

The stereo 90 is called the 100 now I think.Do you think the pre amp had anything with it being compressed?I was looking at the Cronus hard seems like a nice piece but if I was to purchase 3.7s probably would not cut it.

No, the preamp was not compressed at all. It was a Mark Levinson 326s which sounds great on a variety of amps. In any case, the setup didn't sound compressed with his Class D monoblocks.

Yes, the Stereo 90 is now the Stereo 100, an upgrade but still in the same power class. Based on what I heard I honestly don't think the 100wpc Stereo 100 or Cronus Magnum II will be fully sufficient for the Maggies. I love the Cronus Magnum which I run on my Thiel CS2.4 in the basement setup but this fairly robust tube amp might be marginal on Maggies. If Rogue still makes their larger 180wpc monoblocks, those might do the trick.

Oh, I found the review. The Atash monoblocks are actually 400wpc. I'm not suggesting you need these, just saying you probably need more power than 100wpc.

I had it in my head that I wanted tubes this round but maybe I should re consider .I think I am going to go with magnepans 3.7 for sure. it looks like it will be rogues M-180 mono blocks or I have been looking at parasounds halo A21 amp with one of their pre amps.I will check out the Atsah review. Any experience on the parasounds they been running with 121 for almost 10 years now.

I've been using a Parasound Halo A21 on my 1.7s. Sounds great, with plenty of headroom in a 20 x 15 room. Preamp is a Tortuga LDR3v.2; source is a PS Audio PerfectWave DAC II (uncompressed audio files from a Mac Mini and/or Tidal streaming into Roon).

I have no experience with the Parasound amp but it looks like Jonathan does, and I know that inmate John Elison owns one that he uses to drive his Thiel 3.7's.

IMHO, and based on some experience with the Maggies I believe they need a fair amount of power to sound their best, SS or tubes. I just know that my 100wpc Rogue tube amp didn't cut it with the Maggie 1.7.

Good luck!

I started with 3.3's and a McIntosh MC352, I had been a Mac fan for years but they are not a good match with Maggies. I then went with a pair of Bryston 7bst's mono blocks, they were ok but kind harsh sounding. Then I went with a Sanders Magtec which was a huge improvement. I now have a set of 20.1's actively bi-amped with the Magtech on the bottom and an ESL on the top pushing 3200 watts. The added power was not to make the sound louder but to listen at the levels I wanted to safely, I too have a big room. Before I bi amped I went through a lot of fuses and ribbons not so much now since I bi-amped. I also use a tube pre amp that was also a great improvement. I can now say that I am done.

Not to further confuse, but if you want to stay with tubes, also consider the Quicksilver V4's. They currently use KT 150's and are rated at 170 watts/channel.

I have a PAIR of the A23, one per panel with the P5 preamp.
The '23 is the little brother to the '21 and has roughly 1/2 the power.

Nice combo.

Perhaps the Halo integrated?

Don't forget that with any of the x.7 series Maggies, you can NOT biamp without going into the speaker and doing some surgery.

Unless you know about the reviewer, IMO, they are of marginal added value. Ever read a BAD review?

I know a few of you have mentioned the Martin Logan's .I guess this is what you call a Hybrid with powered sub below.,will these produce the same quality sound as the Maggie's? I assume these would be easier to drive beings they have a powered sub on the bottom? I watched a YouTube video with the Martin Logan's Montis El with the Prima Luna HP man does that sound good ! Well it's YouTube so maybe sound is deceiving. Is the Prima Luna good stuff.Here is the link http://youtu.be/s-rtyg1qvb0

Martin Logans are generally pretty demanding of the amp.
They are sort of flat like Maggies, but that's where the similarity ends.
They are electrostatic and have some awful electrical characteristics at the higher frequencies.
The built in woofer taking off 'some of the load' is a red-herring. Don't be fooled.

For a similar price to the Magtech, i'd be real surprised if the Parasound JC-1 was in ANY way inferior.

Too bad the 1.7 needs major surgery for those wanting to biamp. My A23s will end up with more effective power than an A21. As much as 3db more.
