Romy,

Thanks for taking the time to share your thoughts - I really appreciate this.

I'm trying to understand your idea of Severe Mass Deficiency Syndrome. How tightly correlated is this to a speaker's impedance curve? The Druids don't seem to dip below 8R anywhere...

A couple of questions:

1. According to its manual, the Siegfried is a zero-feedback design and has a typical output impedance of 1.5R (measured at 1 amp, 60 Hz). Is this then close enough to your estimated 1.25-1.3R for this attenuator to be unnecessary?

2. If you still feel that it might be a worthwhile endeavour, what do you think is the best way of fine-tuning the output impedance precisely? Apologies in advance if there is an obvious answer to this. (BTW, I share your aversion to soldering irons - is there any way that this could be avoided?)

Mani.
