McIntosh autoformers vs direct-coupled output

Is this just another of those opinions masking subjective bias, or is there technical substance here?

First you need to say the model ML you have, what type of music, if you have ML’s
1: Full range CLS/CLX,
2: Two ways with passive bass driver.
3: Or two way with active bass diver?

There are far better amps than Macs, for the same money to drive ML’s models in general with. As ML's impedance can be as high as 40ohms and drop to very low 0.9ohm, this is not Mac territory in my opinion.

I have ML 11As and picked up a McIntosh MC452.  I spent a lot of time trying to figure out why I couldn’t get some instruments to sound natural, especially violins and pianos.  I found and bought an older MC7106 6 channel directly coupled amp for my center and future surrounds.  I tried bridging two channels and connected the 11As.  The MC7106 brought a more crisper sound to the instruments, it wasn’t perfect since the sound felt a bit thinner probably due to not having enough current.  Nevertheless the instruments were less muddled than the MC452.

Let’s just say I spent a lot of money working around the MC452 not realizing that it was the primary reason I wasn’t happy with the sound.  It’s a great amp, just didn’t fit my preference paired with the 11As.  

What I learned through demoing a bunch of amps is that ML panels naturally roll off highs and are a tad warm.  Match it with a Mcintosh ss amp with autoformers which is also warm, just doesn’t makes good match, for me at least.  It’s all a matter of personal preference, it may work for some.

I liked Luxman the most, especially the 900 series separates, but budget constraint ended with with the 509X.  Others amps work great as well.  Constellation amps, even their entry level line, seem to resonate as well with ML owners, though I never got a chance to demo then myself.

stereo5, you have repeatedly described the parasound halo series as thin and lifeless. I am not sure what your other components were that you paired it with, but I disagree with your subjective evaluation and think you do a disservice to others who may be seeking opinions on what amps to purchase who might pass on these very good amps.
