As an owner of the 4429s'. I think that they are excellent speakers. I have not heard either one of the others. Tannoy used to be owned by Harman also. So probably some cross pollination there between JBL and Tannoy. As far as The Gibbon Circuit is concerned, other people have done similar things like isolating the capacitors and inductors in a sand wax mixture. That would be JBL in the 70s'. They don't do that anymore. They use open circuit boards like most manufacturers today. I can understand that designing crossover/speaker systems that don't look reactive to the amplifier is a good thing, although not practical in a lot of cases. High end amps are usually designed to drive highly reactive loads. That requires a low resistance high current power supply, which usually means, it is an expensive amp. The majority of the cost in building an audio amp is in the power supply. Cheap amps do not have high current capable supplies.
Another thought: The D2girls had a pair of JBL 4367s' that they raved about. But, I would ask the question, have they listened to the speakers that you are referring to here. Bottom line: You have to listen to all three of your choices to make an intelligent decision. Our recommendations may not fit your needs or desires for what you think is the kind of sound you are looking for.
