I was very happy with Mike Powell's silver jumpers and fuse replacement, inexpensive (my set was $75 ) and almost instant install...
I have been listening to my MG IIIa’s since 1988. Peter Gunn generously advised me to screw as much natural wood to the back of the particle board frames as possible to absorb vibration and he shared the schematic for his crossover. I installed 36’ of 2"x3" studs per speaker and built his crossover ($900 in parts). Major improvements.
Recently, Peter advised me to place a screen behind my listening position to enhance bass response. I constructed a frame to hold a 2’x4’ piece of plywood covered with 2" of Rockwool that is mounted horizontally 34" from the floor and another piece of 2’x4’ plywood covered in Rockwool that hangs over the listening area at a 30 degree angle. I had been using an 18" sub with a low pass of 35hz. The sub is no longer necessary, unless you want sub 25hz support. The over all sound is cleaner without the sub. The overhanging panel helps eliminate sound bouncing from the ceiling. It’s like having a folded horn located behind you.
My room is 35’x25’x14’ (tray ceiling). I installed a diffuser on the middle of the front wall and the sound stage bloomed. The Maggies are powered by a Devialet 220. The Devialet replaced a Pass Labs 250.5. The amp is connected to the speakers via sixteen 5’ 0 AWG copper cables.
I highly recommend you consult Peter Gunn and consider buying one of his modified 1.6 QR’s. Unfortunately, Peter does not modify the bigger models due to shipping constraints.
An Audiogon poster, b4icu, recommended the speaker cables. Shocking results as I added one cable at a time.
I have had many box speakers. They sound good, but they don’t have the magic.
@ronboco The story seems "interesting".
The Magnepan (I own the 3.6R’s) sound great out of the box, people have claimed rebuilding the crossover with better quality parts, adding stiffness to the frame help the sound, but I rather doubt it; and reviewers have tried all of these things with no effect other than the usual effects when you change something and you really want to hear a difference. The existing stands could be sturdier, but the third parties making replacement stands want $500 which is preposterous.
The only real downsides is their power demands are tremendous and you have to fine-tune placement more than with other speakers (and the 3.6 line is about 6 feet tall). But the flip side is that even played at high volume the sound says clear and well balanced, which I can’t say for a lot of speakers.
To each their own.
Magnepans sound great as is...but can be improved with various tweaks or rebuilds, some of which can be quite expensive, though some are cheap...sometimes have to decide between tweaks and stepping up a model or two...and after years of debate, Magnepan now offers upgrade stands for some of it's models...
Even though Magnepan emerged from the primordial soup of early 70s HiFi virtually joined at the hip with Audio Research Corp., Wendell Diller, who helped guide the company from the getgo, is a man of the people. His world view is closer to Hubert Humphrey’s than Thurston Howell’s. He has resisted inflating the cost of the speakers beyond what’s necessary. He is an evangelist for boxlessness and wants people of modest means to be able to enjoy.
I am definitely not disparaging Magnepans. They are very popular and must be a great value for the price. It just seemed odd to want to upgrade a speaker as soon as you buy it. Listen up in Denver sells them and I think it’s time to go have a listen to them.
@ronboco I didn't take it that way at all.
I bought my Magnepans used in perfect shape for a fraction of what you see them typically sell for used, so it's not like I have some allegiance to the brand. I think they're cool, but I don't think they're the best thing I've ever heard; they' simply fell into a price/performance range that made them worth trying. They work for me because my time to listen is on weekends, work is just too busy.
Jl35 +1 Has anyone bought what they considered to be a great car, at least for the money? Would its performance, looks or comfort be enhanced by some aftermarket shocks, struts, tires, larger rims, carburator, spark plugs and wires, or even a turbo or supercharger kit? Extra cupholder? Same difference.
