I don't know what the first one was, but more recently in HFN, almost
anything by David Allcock gets me going. It's almost as if he's
deliberately trying to live up to his name......

His latest, page 56 of the January 2006 HFN, when reviewing a passive
(note, passive) preamp (that, in itself, is a misnomer..its a switch and a
variable resistor....) he goes on about how "Stage depth was slightly
foreshortened" Give me a break, it's a resistor! how can it
"foreshorten" anything?


**Try it yourself. Load down the output of any given source by an
excessively low impedance load and unpredictable results ensue. Passive
controllers are often configured to present a low(ish) impedance load, so
that their source impedance is low enough for successive stages. The whole
issue can be easily and non-intrusively solved by the simple addition of a
buffer stage.
