The key part of attenuator autoformers or transformers is that you do not get the added resistance of the Pot/Stepped attenuator. As long as you use resistive elements to do the attenuation, you might as well leave the transformer out, unless it has another job in the bargain.
If you don't believe, try borrowing an MF Audio passive preamp and compare.

I'm pretty sure that is what Andy said. And I can confirm that I got better microdetail and transparency...but that is probably because these things are in the signal path anyway...and i bypassed everything that comes after...
To say that it comes close to a transformer attenuator is another thing completely ofcourse...but that is not what I said. Maybe implied..but not said ;-)

Bas,

Fine. But he is nevertheless quite wrong. I know Andy quite well BTW and know where he is driving with that.
