Hi I am a new comer into the world of TAG Mclaren. I have just purchased an old AV32R 5.1. I have copule of questions: Whre can I buy the TAGtronic Programming cable so I can upgrade the software. 2: I hace an ARCAM 9 Amplifier and an ARCAM DV88P with B&W 800 series speakers. Currently I am using an ARCAM AVR300 processor. I want to know will I get a much better performance from the AV32 than ARCAM processor or I need to upgrade the TAG. Finally I paid £670 for this unit. Can someone tell me whether this was over priced or is it reasonable as I really do not know how much these units are worth Thanks for your help and sorry if the question are obvious.
