MMGs

A year ago, I bought a pair of MMGs.  In my 13x22 room, placement was a challenge but finally worked it out.

Speakers are powered by an Adcom GFA-555.  The only source is a CD player through a passive pre-amp.

Now I have a little more to spend and would like thoughts on the following options:

1) Mye stands for the MMGs

2) The DWM panel with the MMGs (secondary question - can this panel be placed on a side wall perpendicular to the MMGs?)

3) 1.7s

Open to other out-of-the-box suggestions as well.

The goal is always to attain that Magnepan soundstage.  Musical tastes are female vocalists, jazz, blues.

1.7s without a doubt

DMGs can be tricky to place correctly and need to be in front of the arc (from the users listening spot) the main speakers are on (IIRC from talking to Wendell)

Mye stands and similar are of no use.  Dipole radiators do not have the same movement issues as box speakers, and you will not improve phase coherence at all.  if you don't believe me call up Maggie and ask Wendell...

I recently upgraded from 1.5's to 3.7i's and the difference is revelatory.  I spent several hours comparing the 1.7(no i) to the 3.7i at a dealer's and they are pretty close.

re Gunn - There is no advantage to changing the surrounds or in bracing the speakers.  If you think there is, then you do not understand how dipole speakers work.  But don't trust me, call up Wendell and ask him.

The x.7's (any of them) are a big advantage over previous speakers.

an Adcom is fine - you want good current output at 4 ohms

Maggies do NOT represent a complex impedance

re: "I’ve seen MMG’s measured in UW-Madison engineering lab at 2.8 Ohms .
Not complex but LOW ."

Yes, the 4 ohms is an avg. over some dips & peaks along the freq. range.  That's about what TAS or S'phile measured, don't recall if it was a 3.6 or 3.7.

But he can surely use his present amp and compare it with others to see if he wants to replace it.  Moving them around & building polyfusors will likely be more productive -- not to mention finding some source material with decent DR...

what makes you think that MDF does not "soak up" vibrations at all???

May I suggest some reading in the engineering literature?

the DWMs need to be placed closer to you and further from the wall than the main speakers

I agree - get 0.7 or 1.7 - see if a dealer is near you to listen and for a home trial; call Maggie and beg them to extend the free home trial from them direct if no dealer nearby.

While on the phone see if you can talk to Wendell - see if he sighs or laughs when you mention big stands or maple surrounds.

Don't get caught up in the woo-woo - besides, you will spend plenty of time moving them around in the room...
