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.

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

May I suggest some reading in the engineering literature?

Given that you like your MMGs but are moving to a 13x22 listening room, your situation practically screams for the Magnepan 1.7 or 1.7i.

I have been enjoying my 1.7s in a 16x18 vaulted ceiling living room (plus front hall and dining area in an open architecture) for 3-1/2 years. I like 'em better every time I fire up the stereo.

I must have gotten lucky, but high current MOSFET amps make driving the Maggie 1.7s easily. Here are some candidates:

Parasound Halo A23: 125/200/400 wpc into 8, 4, and 2 ohms respectively. All the power, current, and stability you'd need. $995.

Parasound 2125v2: 150/225/225 wpc into 8, 4, and 2 ohms respectively. $795. Really cool feature: High pass filter settable to 20 or 40 Hz. This can be a help to the Maggies by not feeding them a deep bass signal. Especially handy for getting a smooth blend with a subwoofer should you go to that later.

Odyssey Khartago: 110 wpc and stable into 2 ohms. Considered a major overachiever at $999. These amps are used for testing and voicing the highly regarded Magico loudspeakers.

If you sell your MMGs and GFA-555, it should mkae it easier to get the 1.7 or 1.7i Maggies and a Parasound or Odyssey amp.

Added pictures to my virtual system to show what I am dealing with in room layout and listening position.

Johnnyb53, there is a Parasound Halo A23 for sale on here at $50 less than original list for a four year old unit.  Does that seem reasonable?

I saw that A-gon listing and it had me scratching my head. You can get a brand new Halo A23 from AudioAdvisor for $995 with free shipping, probably no sales tax, and a 5-year factory warranty. When you add the A-gon listing’s $944 plus the vendor’s shipping ($37) for $981 total for a 4-yr-old unit, the $14 saving hardly justifies the risk differential.

I’d go for AudioAdvisor or any authorized dealer’s new-with-warranty Parasound Halo A23 over the A-gon listing, no question.

If the 4-yr-old unit was $795, then maybe.

Kythyn, I have a set of Maggie 1.7s in a room much the same size and configuration as mentioned by johnnyb53. I'm driving them with a Rouge Cronus Mag. II 100w per side integrated tube amp and it has no problem driving at any level I can stand to listen to - I listen to much the same styles of music as you. I also have a ADCOM GFA-5500 and with 400w per side @ 4 ohm, it has no problem driving the 1.7s. After 8 or 10 good hours of warm up, the ADCOM sounds pretty darn good with the Maggies, just not as sweet or open as the Rouge.
Just a thought - go for the 1.7s or 1.7i (around $1,200.00 used) go with your Adcom GFA-555 (300w per side @ 4ohm I believe, should work fine) for now and upgrade your amp as you can. 
Best of Luck,
Jim
