MMGs

kythyn,
I have had a pair of MMGs and one DWM in a 15 X 20 room with a vaulted ceiling for about 2 years. The panels are 2 feet out and 6 feet apart on the long wall.  150 watts has been plenty of power. I had a B&K 2140 for awhile and replaced it with a  Van Alstine Synergy 240 with the double die option about 6 months ago. Its a great sounding amp that has never run dangerously hot at reasonable sound levels. You can occasionally find used Van Alstine equipment at the usual online spots and the company website avahifi.com.
I went through a variety of small to big tweaks for the speakers. Adding weight to the feet with teak blocks and replacing the fuses mattered but not enough. I have to agree with chattaudio about the Gunn improvements. John very graciously shares his design with anyone willing to take on the project. Having finished mine a few months ago, I can honestly say it was well worth the effort. In part, the Gunn upgrade stiffens panel mounting. The Mye stands might make difference but never tried them.
 It has taken some time to find the right DWM placement. It seems best on the perpendicular wall just ahead of the MMGs. They add very little at low listening levels but start to bloom with some volume.
Another two cents,
Scott

 

Not sure what you're using for a preamp but with $2500, I agree with everyone's suggestions to upgrade your amp with  used ones until you find the sound you like, using half the money. Only consider high current amps. I haven't heard the Odyssey but the  Rogue integrated brings some warmth to the MMGs and the Parasound was worth a listen. I like the Van Alstine Synergy 240 I'm running now with a Van Alstine T10 tube based pre.

If your CD player has a digital output, you could use the other half of your budget on a decent DAC. You may be surprised at the difference. The DAC market is little crazy so listen to as many as you can to get an idea of your voicing options and what fits your tastes.

 I have only heard the MMGs in my house so I can't comment on the sound of either the .7 or 1.7 models. I can say the DWM brought subtle depth and noticeable dimension when placed correctly and wired out of phase. It is hard to disagree with issues about the cost effectiveness of the gunn rebuild in an under $5000 system. It is  a complete transformation of the stock speaker, replacing the MDF frame with a solid wood structure, reorienting and rewiring the driver and rebuilding the crossover. Great project if its your thing but otherwise pretty daunting. Unfortunately, they may send you on an upgrade path that goes far beyond your original budget plan. A used  DWM might fit in  your budget with the right amp and dac and fit the sound profile you're shooting for.
