Sancho Panza was a kind of technical servant of Don Quichot.
As was the case in those old times all the merits of an servant
belonged to their masters. So those pre-amps, tonearms, headshells
etc, as pretended inventions of Raul are actually made (or not)by
his Sancho Panza. Don Quichot himself was not even able to fix
his own blown up midrange speakers. I think that Sancho Panza
discovered that slavery was abandoned and started for him
self. This (should) explain Halcro's wondering about those missing
tonearms and other promissed components.
