Magnepan 1.7 too bright, HELP

I went through same issue. I listened to them through high end ARC tube amps in my dealers showroom. Loved them. Purchased the 1.7's with a new ARC LS17 and brought a pair of BelCanto M3 mono blocs home with them for demo. I hated the sound when I got home and set up. I then went to my other local dealer and purchased a new Bryston 4B SST2 to try with the 1.7's. 10 minutes after installing the Bryston in place of the BelCanto's I loved the sound. The bass was so much warmer and more natural and the highs lost the artificial sheen I was hearing with the class D amps. I also installed two absorbsion tubes in the corners behind the speakers. Everything sounds wonderful now. These are amazing speakers if paired with a tubed pre and a high quality and potent SS amp. As others have made clear, they will show you any mismatches or weak links in your audio chain rather quickly.

Another minor tweak is replacing the hard metal bar jumper with either a copper or silver high quality jumper. This is by no means a make or break tweak IMHO, but it is well worth the few minutes and minimal cost. I have tried both copper and silver and settled on silver Audioquest jumpers that cost $25. It removes a minor bit of upper end shine (for lack of better term) at least with my components.

Hi Jazzdrummer1969,

What source, pre and amp are you running the Maggie 1.7s with?

Glad to hear you are enjoying them. I had a really hard time getting them to sound right in my room. I have very similar room dimensions, but my room is awkwardly shaped.

Enjoy!
