It's survival was based on the litigious nature of Dr Bose, combined with a superb marketing department and dumb patent issuers. It's present survival is based solely on Bose's need to keep the illusion alive. Bose sells so few of the model that it is impossible to justify, based on sales alone. There never was anything to praise the Bose 901 on. "Helically wound voice coils" indeed!

In fact, I visited one of my best clients last Monday. He is still using the same amp and preamp I sold him, back in 1988. It still functions well. A step up from his previous equipment, which was unsatisfying, unreliable and provided a poor resale, when he finally tired of it. > >> Oops, I forgot that you are >> > a hi-fi salesman. > >> **Indeed.

However, there are a raft of other choices, in the real world. The person who THINKS he is honest, advising people, whilst he possesses no real knowledge about the subject is dangerous and is still a con man.

These include: * Source impedance. * Impedance of the cable. * Impedance and efficiency of the speakers. * The location of the short circuit. * The actual impedance of the short circuit.
