Removing Zobels from commercial amps is an audiophool pastime. A client was charged handsomely for the service. He kept wondering why his tweeters kept blowing... He brought said amp over to me... Square response was shocking, although not as much as the smoke emanating from said amp....

Harold Black was one of the greatest innovators in audio. His discovery was NFB, which audiophools rail against (am not equating low global FB with lack of stability btw - too much FB can cause instability in some circuits). Same audiophools rail against Mr Zobel's invention.

One day I shall market a 'high feedback amp' - with a Zobel!
