Tube amp with Magnepans?
I picked up a pair of MG-1 electrostatic speakers.
They are nominally rated at 5 ohms impedance. I am interested in suggestions for minimum wattage and brand of tube amps that might drive them nicely. Or should I venture into the dark side? Jon |

Magenpan's of this sort have an almost resistive impedance (confirmed by measurement), so damping factor isn't a huge concern. I would aim for push pull pentodes or beam power tubes, with power in the order of 50-100W. The only real issue here is adequate power output to combat the low efficicency of the speakers, but this will most likely be limited by the rather low maximum SPL of the speakers and not the amplifier. Obviously, the quality of the output transformer is no less critical than ever, and it will determine the overall quality of the sound. I love my MG-IIb's with classical music, especially strings. I would say they're the best violin and cello speakers I own. For anything else, they are much less good. Your REAL issue here, is going to be making sure that the aluminum voice coil wire is still adhered to the pastic membrane. Early Magnepan speakers have some known problems with voice coil and adhesive breakdown, and if they haven't been serviced before, they will require attention almost for sure. The early adhesive not only fails, but when exposed to UV begins to attack the aluminum wire, leaving it brittle and full of a green residue. A web search will turn up numerous descriptions of how to address this problem - in my instance it drove them into the closet, as I got tired of their limitations. OH - one more point. The speakers are very directional in the higher octaves, and placement is very critical. It is also important to have them far out from the wall, to give them some breathing room. In general, if you are serious about Magneplanars, and like your MG-1's a lot, I would seriously consider replacing them with a better model rather than upgrading amplification, because MG-1's have a lot of well documented technical limitations which will prevent you from hearing subtle differences in amplification. |

I am interested in suggestions for minimum wattage and brand of tube amps that might drive them nicely. Or should I venture into the dark side? Jon Er Jon, the Maggies are not electrostatic; see the m-a-g in their name? They are bipolar, and radiate sound rearwards and frontwards, so they need a good room and good placement. They comprise bass panels with attatched voice coils with a mid/treble ribbon top to bottom down one side of the bass panel. Well, the last pair I auditioned here were like that, and were about 1.2M tall and 450mm wide. A customer of mine wanted to buy a pair and trialed them here in comparison to an early version of my dynamic speakers I'd built using 12" Electrovoice bass in 120litres for 20Hz to 250Hz, 2 x 200mm asian generic paper coned el cheapos 250Hz to 3kHz, and a Response 25mm dome tweeter. This way he could evaluate the Maggies, my amps, and my speakers all at once, and I would know whether Maggies were any better/worse than what i could build. He'd been sucked out dry by a wife in a bitter divorce and was re-equipping his new abode. We spent two nights of evaluations with a wide range of music in my very decent listening room. The amp we used was an 8585 with 4 x GE6550A per channel, with high amount of class A, so pretty decent amps, imho. The maggies did not have a wide soundstage or as much treble detail or have as much bass as my own speakers in relation to the midrange. We both agreed they didn't cut the mustard as well as what I'd made, but because the price was only aud $700 being asked, the guy bought them anyway, knowing he could boost the treble and bass with his tone controls if he wanted to. We had them ideally placed, and did try various positions, but it didn't seem to help them. I don't want to buy a pair. Later I made another lot of speakers using all SEAS drivers and these were easily MUCH better than the asian drivered speakers I'd compared to the maggies, which means the maggies are even worse than what I have already said. Sensitivity was about the same; somewhat deceptive though. Switching to the maggies after mine was like being moved immediately to the back seat of the concert room. Trevor Wilson takes the opportunity in this thread to say again how crummy and awful some SET amp was somewhere but don't listen to his fact free crapppy tripe on SET. He likes to **** in our r.a.t loungeroom nearly every time he "discusses" SET amps. SET amps would be VERY GOOD with a speaker like the maggies. It would not matter too much if the Rout was a bit high from the SET because of the maggie's flat impedance curves. If there was any type of amp the Trevor Wilsons of this world might complain about it could be any OTL amp using tubes because the OTL amp you do see occasionally sometimes do have appallingly high Rout, since there is no OPT to transform the Ra of the tubes down to get low Rout and also a good load match. However, if anyone buys a ZeroImpedance toroidal matching transformer which can RAISE the ohmic load seen by the amplifier then the OTL then becomes a good amp to use; 5 ohms maggie Z is a bit low for many OTL. Also low for many SE amps which have been made to suit 8 ohms. But whatever the amp, it WILL need sufficient power, and most SET amps don't have much power, simply because there ain't enough 300Bs on the chassis etc.... Probably a 50 watt amp is more than enough for most ppl, and if SET amps is all you had, you'd need to have them carefully matched to the average load, and able to make at least 35 watts, and then at moderate levels you might get reasonable sound. The guy here who bought his second hand maggies for $700 used an old NAD receiver with about 35 Watts of SS power per channel, and he wasn't complaining when I visited him one day and had a listen. I will never forget my first experience of a pair of decent SET amps back in 1996 shortly after I'd joined the Audiophile Society of NSW ( ASON ). There was a meeting at a leading Sydney high-end dealer's shop where several systems were being demoed in various rooms. In one, 15 of us sat around listening to a system with 100W per channel Gryphon Class A PP SS amp and some high end ARC preamp and a good cd player. Speakers were two 4-way towers of stacked enclosures with sensitive drivers, with a system value of maybe $50,000. Sound over a range of CDs wasn't too bad, generic SS, and as "accurate" as anyone could hope for. Then after about 40 minutes, the power amp was changed to a pair of class A 23 watt SET amps with little NFB. Instead of bland boring "accuracy", we had real lively foot tapping dynamic musical music. 14 guys suddenly heard the veil lift and music begin; it was a night and day experience. But one poor guy of the 15 wasn't happy at all. He'd just bought a Gryphon, and had to admit the SE triodes sounded far better!!! The power levels used in demos like this seldom rise beyond the 5 watt peak level, mostly less than a watt average levels. I've been to several meetings where the amps used had power meters, and power used was very low; a classic example was where two ARC Reference 600 Watt monos were being used to drive top range Thiel speakers, and the power meters hardly moved at all, and the PO being used could not be measured because it was so low, yet the speakers easily filled the room with sound. In the ASON newsletter after that meeting I went on to describe the ARC 600 watt amps as being like a Rolls Royce, but with 16 driving wheels because there are 16 x 6550 within each mono amp, and were something I couldn't want to own, because they'd own me, and two driving wheels are plenty. I have since learnt how utterly ****fully ARC build their amps, and most definately cannot recomend anyone ever buy one, unless its a lower power early model that can be re-enginered for reliablity. So anything with a pair of KT88/KT90/6550 will do for maggies, a pair of modded Dynaco Mk-III would be fine. Patrick Turner. |

I remembered that among my projects is the rebuilding of a Citation II,
which ought to be able to drive them, especially if I use KT90s. I think those amps deserve better speakers, honestly. They're some of the best vintage amps ever made, and would be truly wasted on MG-1's! Of course, any excuse to rebuild them, is of course a valid one! My "other" set of speakers are JBL Century 100s. I got the Maggies to experiment with; I wonder if I will prefer them over the JBLs. I have a feeling it'll be MG's for some stuff, and the JBL's for everything else. My personal opinion, and experience is nothing touches a good set of Tannoy speakers. A set of expensive Tannoys connected to that Citation would be almost enough to kill the entire desire to upgrade your hi-fi. |

If you can hear something from the classic series set up properly, with good equipment and recordings, and in a good room, you'll be in for a treat which exceeds all expectations. Another very experienced friend said he felt the Eico HF87 or Acrosound UL2s were better sounding than the Citation. We shall see, eventually! I don't own any of the above - have an uncle who has owned a Cit. II since it was new, haven't heard the others. I just know from my experience with Magnepans, that the model you own is seriously outclassed by something like the Citation. |

The room they will be in is 24' x 17' x 10' (7.32m x 5.18m x 3.05m) and pretty lively. All that I have been able to gather suggests that these sorts of speakers want a large room and are acutely sensitive to placement. I hope that Jon's double-wide is large enough ;-). Peter Wieck Wyncote, PA ** Peter, SMGa's make wonderful near-field speakers, set up maybe 3 feet in front of the listener's seat and spread out 4 feet or so apart, toed in.. 30 watts of tube power per channel in this case is more than enough. Fred Fred: Thank you. We will certainly have plenty of room in which to experiement. And I have tube amps ranging from 15 watts to 75 watts, SS amps from 40 watts to 200 watts to play with. I am leaning towards tubes in this application - but time will tell. Funny thing, you are the first to suggest 'near-field' placement, but all seem to agree that some distance from the wall between 2 and 4 feet and 'toed in' to the sweet-spot. Ah, well. More fun to be had. Thanks again. Peter Wieck Wyncote, PA |

Tube amp with Magnepans?
"maxhifi" wrote in message ... I remembered that among my projects is the rebuilding of a Citation II, which ought to be able to drive them, especially if I use KT90s. I think those amps deserve better speakers, honestly. They're some of the best vintage amps ever made, and would be truly wasted on MG-1's! Of course, any excuse to rebuild them, is of course a valid one! My "other" set of speakers are JBL Century 100s. I got the Maggies to experiment with; I wonder if I will prefer them over the JBLs. I have a feeling it'll be MG's for some stuff, and the JBL's for everything else. My personal opinion, and experience is nothing touches a good set of Tannoy speakers. A set of expensive Tannoys connected to that Citation would be almost enough to kill the entire desire to upgrade your hi-fi.´ Interesting observation. My own quest for speakers to suit my taste, has resulted in similar conclusions. Tannoy, JBL (and of course B+W 801D) Iain |
