Magnepan 1.7 too bright, HELP

Well you sort of opened a Pandora's box when you asked this question. My advice, don't spend any money right now, especially on cables or power cords. First play w/ the speaker position and the see what you can do about the room interactions. Post the dimensions of the room, where the speakers stand in the room, and what you have behind the speakers. Start with the room and speaker placement before you buy anything else. You've got a speaker, for better or worse, that is sensitive to what's driving it; however, even w/ very high end equipment Mangepans can still perform well below par if they are not placed correctly. With some more detailed information about your room the folks here will help you optimize your acoustics, first priority.

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.
