Wellfed your points are well taken. I however agree with Trelja in my experience with the autoformers. I found the 1.37 setting the best. 2X was ok but anything above that the sound became whiter or more solid statish losing much of the natural sweetness intrinsic to the Transcendent amp I used it with. Indeed the bass was improved. It seems this device designed with the Atma-sphere in mind decidedly didn't do what I needed in my system. I liked it at first but found myself over time going back to direct most of the time. What I needed was more OTL power.
I feel the zero autoformer is a very well priced well designed product that will benefit some systems more than others but bear in mind that the character of the sound changes the higher the multiplier.
