There's a persistent thought that Magneplanars are a difficult load for a modern amplifier. Paul does his best to diffuse that.

I have a pair of Magnapan LRS+ that constantly amaze me. The clarity and spacious sound stage when you get them set up properly can surpass much more expensive speakers. I was apprehensive about being able to drive these with my Yamaha A-S801 after watching all the videos about how you need a lot of current, etc. I was assured that I had plenty of power, so I took the leap. I think it was the best thousand dollars I ever spent! My Yamaha drives them louder than is comfortable, and barely gets warm! Thank you for confirmation. Maybe this will clear things up a little.

Hey Mr. Magnepan , before you switch amps a crossover upgrade would be a good move along with a stiffer stand brace. After then try a PS Audio . 😊

I used to power a pair of Martin Logan Aerius with a pair of Lumley Reference M120 monoblocks and every now and then the amps would start going into an oscillation mode with one of the plates glowing bright red and another tube replacement. I am sure it was because the impedance curve of the speakers created the feedback and that the amplifiers didn't have the damping factor to recover. Real shame as it was a lovely sounding system. I'm now running ESL13's and a fairly powerful transistor amp and no problems in the 5 years I've owned the system.

You can probably point the finger at Apogee for this misconception.

@VideoArchiveGuy 23 күн бұрын

Even there, there was ONE Apogee model - the Scintilla - that was hard to drive because the impedance dropped to one ohm. The rest of their product line never fell below 3 ohms and had a nominal impedance of 4 ohms.

@computerfreakch8912 22 күн бұрын

Most amplifiers are designed to drive dynamic speakers. Using high voltage power supplies with capacitors to deal with peaks on the impedance curve. Magnepans, with their low-ish impedance and low efficiency, might deplete the capacitors if played at high volumes. On top of that, they are revealing enough to expose any weakness of the electronics. This is the best explanation for Magnepans to have the opinion of difficult to drive speakers, that I could come up with. High quality amplifiers should not have difficulty driving them without distortion. Avoid cheap class D amplifiers with brick power supplies ;-)

audio amplifier , complete with a good speaker systems changes with technology , older solid state system are based on bipolar junction teransistors , class AB amplifier , while a modern amplifier uses high power mosfets which utilised the latest lateral diffusion technology for better and higher power mosfet transistors , so it goes on changing and never actually stays the same .

@carlosoliveira-rc2xt 22 күн бұрын

I've been saying this for decades but people are stubborn. Maggies are a resistive load which is pretty easy for amps. Their sensitivity is very low so they need power. Look not only to a low impedance load but also to phase angle, the two together make for a difficult load.

@@jaakanshorter this is for the 1.7i Maggie’s. Peachtree Nova 300 sounded absolutely lifeless and flat. It has no problems driving the Maggie’s to volume but it just sounds bad. Yet it sounds full on all my other speakers. I’ve also tried a few of my vintage receivers. The Yamaha CR-820 for instance was also lifeless compared to the Marantz 2252B. Obviously both were a little underpowered. With my other speakers the difference in any amp is very subtle. Regardless if it’s a vintage, integrated or separates. The only integrated I’ve had good luck with on Maggie’s is my Luxman L-507z. My McIntosh MA-5300 sounded just OK but ran out of power too quickly. Most High end class AB amps work OK as long as you have a minimum of 200 watts into 4 ohms or you run out of headroom. Maggie’s also like Bryston 4B amps much more than the Parasound A21. There is no real difference on my Klipsch LaScalas between those amps.

I've had a Magnepan home theater setup consisting of 4x 2.5R and a CC3 center. I originally drove them with separate amps but later switched to a receiver (class D Pioneer Elite sc901). Touch wood, I've never had an issue despite lots of action movies. I do use powered subs and cross them at 80 Hz.

@joso5554 23 күн бұрын

You practically can (nothing will burn or explode or destroy your ears) but it might be anything between an ok result and a major step backwards. Depending on how the cable you are using can properly transmit high frequencies in the megahertz range, and have a coaxial impedance close enough to 75 ohms. If not, the digital message will be distorted along the cable, or will suffer multiple reflections back and forth at the cable’s ends, adding up into an even more distorted digital stream signal into the DAC. So that the DAC may get confused between 0s and 1s regularly, which obviously will poison the ultimate decoding and analog signal result. So you can try and some RCA analog cables will certainly be ok, but some others will definitely be shitty. In any case, digital coaxial cables are those meant for proper transmission of digital streams. Don’t be confused by the fact that the RCA plugs are the same.

@@joso5554 Great advice. Digital cable is build for 75 ohm and faithful transmission at the spec'd data rate. With digital it can be perfect but generally goes down hill from there. You can't make it better. Digital is prone to subtractive distortion. IMHO, most digital playback is done with something short of 100% of the information. The better you get at bit perfect low jitter playback, the fuller and more natural it sounds. Give up half the bits and it still is recognizable, but harsh, thin and irritating like all those early CDPs.

I’ve owned 3 pairs of Maggie’s in my life, even though I realized after the first pair they aren’t really for me. My experience was, they are great for vocals and acoustic, 2nd to none, and they’ll do that with almost anything. But if you want to play rock n roll through them, or hip hop, you need something with some power to get any bass, and even then it’s not great. That was my experience anyway

@andrewfurst5711 19 күн бұрын

I never owned Magnepans but I auditioned them extensively back when they were available at retail audio shops. I felt the same way you do, when I first heard solo piano through them I was ready to buy. They were very open sounding and great at midrange. But before I purchased, I auditioned some favorite CDs with a full rock sound, and they were hugely disappointing. Even the more expensive Maggies (than I was originally considering) and even with the shops biggest amplifiers, the Maggies sounded mushy and washed out. Cymbals virtually weren't there, and there was no "punch" in the drums. It sounded like a wet towel was being used as the driver for the speakers. This was about 30 years ago but I was so put off by Magnepans that I never wanted to hear them again. People say they are better now than before, but it seems the same problems generally exist. I am very happy now with my Martin Logan Motion 40's (the originals, I don't have the newer 40i speakers). I guess I could see owning some Maggies if I limited them to solo piano or other limited-range music. But I'd also have to have another set of speakers to play all other types of music.

Ya know, it’s not a live stream. You can wait to record until your stomach issues have passed…no pun intended. And yes, there’s a difference between efficiency and a difficult load to drive. Certainly inefficient speakers like Magnepan need more power to achieve any given volume. But that doesn’t equate to difficult to drive.

@delstanley1349 22 күн бұрын

The Maggie rep probably comes from their affordability. And affordability with high end speakers makes room for mediocre to cheap amps into the system. I suspect listeners with audiophile amps, may or may not like the Maggies, but I bet they never complain about the ability to drive them. That's taken care of well before hand. If you could get a pair $200K Wilson's for $200 I bet you would start hearing that Wilsons were the hardest ever speakers to drive. You don't hear it because those purchasers are already in a class with the right muscles. Just because a good cow is on sale doesn't mean a 90 pound weakling can go and pick it up. Audiophiles always take big Butch with them. And so, for them, driving speakers is hardly ever the issue---other issues maybe, but not that one. I suspect that Maggie actually liked the rep.
