In Reply to: RE: I'd get a decent 2 channel amp for the MMGs and something else for the other channels... posted by David S. on August 26, 2014 at 12:10:55
LOL! David, I use HCA Parasound myself (2, on bi-amp).
Yet, it was my old NAD 2200PE power amp that first made my MMGs display untypical dynamics and slammy bass. The first time was playing David Sanborn's Tequila...those bass notes at the start show the beauty of a well-designed strong power supply.
The original NAD equipment was well designed & decently built for the times. It is a pity that all this has been rendered "unrefined" after 30+ years. I keep wishing to do surgery and rebuild the NAD...wishful thinking :-)).

Yeah, the 2200 was a really great amp with a number of speakers I used it with, but oddly, it didn't have very good control of the bass with my Maggie SMGs.
Weird - maybe the MMG presents a greatly different load in the bass than the SMG did.
In my case, the preamp/linestage was either a NYAL Moscode Minuet or an ARC LS3. Using either, the NAD had poor bass control, and the Adcom rocked the house. I'll never knock the NAD 2200 - it was the best amp at ANY price I tried with my DALI 8s, but it faltered with my Maggie SMGs.
Goes to show you - DON'T judge ANY given component on its own.
David, your observation is right on the money as far as what would have been perceived. It would have appeared as if "out of control".
The interesting thing is that it was the dynamic punch of the 2200 which revealed a weakness in many Maggies, more so in earlier days. Their frames were a bit too weak. When put to such impressive dynamism as the NAD could send at low frequencies, the sound came out muddled. Strong bass was perceived as fuzzy and out of control.
At the time I hooked up the NAD to my MMGs (which are VERY old), I had already cured the weakeness. Bass from the NAD was tight, clean, and plentiful.
Yet, later on I had a taste of what your heard. One day I conducted some tests of "Razoring" (a tweak by inmate Dawnrazor [on sabbatical] : - )) ) which went on for several weeks. At some point I used the NAD while I had removed the "cure" mentioned earlier. HORRIBLE fuzz on bass-heavy and on full orchestral passages!
The "cure" is to add frame reinforcement. Or, like some do, to replace the factory frame. In any event, if someone had applied the same thing to the SMGs, I am sure that they would have improved also.
So, any of many Maggies would have shown some stress unless reinforced. Actually, the issue persists...
