MAC Autoformers?

I am not a Mc fan, nor am I a proponent of auto-formers such as speltz's, but I wouldn't be so quick to shun them or their use by Mc. Transformers are a mature technology that modern audio has only begun to tap (pun intended), ie- amorphous (metallic glass) cores are seldom used. One reason comes to mind, transistors typically don't have the same transfer characteristics between P and N types (PNP/NPN) and transformers allow use of one type for push pull operation. For me the "whole" is far more important than the parts.

go with a model with autoformers.

The MC7200 is one of the finest amps ever made by McIntosh BECAUSE it does not have autoformers (another being the MC122 - no meters though, 80w).

You have to admit this is confusing. Now it seems that Mac uses the autoformers in the "higher end" units. Why would the do that if it hurt performance? I can't imagine they don't have technical competence and the autoformer is some kind of bandaid for inferior SS design chops. Aball, where are you?

I would guess that that a Mac with autoformer will sound good => better => best depending on the speaker load. A very demanding speaker load, the autoformer will be of a benefit, therefore, in theory, better sounding. A speaker with a very benign load will sound better when used with a non-autoformer amplifier due to the simpler topology. Or, you can listen to both amplifiers and pick the one that sounds the best to your ears, but that makes for a very poor forum discussion.
