Magnepan 1.7 too bright, HELP

Djcxxxis giving good advice.
Usually the advice is to throw money at the problem...
Enough money and the problem will disappear.
Better to solve the problem with no money, or very little money. Then you've got something going.
I used the things in my apartment and rearranged some stuff behind my Magnepan 3.6s.
I added some bookshelves to the rear sides of the speakers to act as an absorber. They are right into the rear corners, floor to almost ceiling filled with DVDs etc. Then in the other part of the corner are heavy drapes.
I have my 3.6s with the tweaters 'inside'. I calculated a good position for my speakers, and then left the tweeter in that spot, but swapped them so the bass was on the outside of that position. Worked well. Wider, with no hole in the middle. And a better appearance too. A little better lower frequency response added in.
So try adjusting the room some. You may not even have to buy anything to get some good from it.
And then in the other site for your question, i mentioned some ferrite on the disc player cords, interconnect, and power cord. Radio Shack has some, and others, so a $15 set of three ferrite might help a bit.
I have ferrite claps I bought 20 years ago, and always find new things to do with them. So they can be a permanent part of the arsenal of things to use to adjust stuff.
One other thing i just thought of is the coil in place of the resistor for the tweeter.
Over on AA the planar asylum, a tweak of using a small coil in place of the resistor, smooths the HF. The coil is like a $2 part. i do not remember the value. but check out the AA planar forum for it.

I agree with Djcxxx. For example, if the bass is not right, that may cause them to sound too bright. Make what you have work to the best of its ability before you spend any money.

Use 1.5 ohm resistors.

If you read all of the string, and know Maggies, the problem starts with the amp. Positioning et al is not going to change the fact that there's not enough juice to run the panels, and the other gear tends to brightness anyway.

Just wasting time.

There is a lot of good advice and good ideas here. The take home message is that most of what you have may not be the best match with the 1.7's.

I'm with Macdadtexas on the importance of good clean power. I use CAD 500 MB's with my Maggies. Unfortunately you are not going to spring 3-4K on an amp right now. You are trying to work on the cheap, so here is my hierarchy using mostly suggestions from the threads. Buy used to save money. Each one of these will help.
1) < $200 Deaden the corners, floor to ceiling. Glue Auralex panels to blue insulation pannels. You may be very surprised.
2) < $500 Promethius TVC volume control. I use a Promethius Ref 4 with my Maggies. You will want to watch the length of your IC's and use an amp with a reasonably high input impedence if possible.
3) < $700 I like the Eastern Electric DAC suggestion above. I've had Denon players with Maggies before and they were not a good match.
4) As Macdadtexas points out, you can do all of the above and still not completely fix the problem. But it sounds like you may need to wait a while before you can really get an amp that will do justice to the maggies. Just keep in mind that you are going to need to get the amp replaced at some point.
