I have the AV32 Bp192 and it has the 5.1 bypass. I would like to added advantage of the TMREQ system, and the improved DP upgrade. Anyone know if it's stilll avvailable at IAG, and at what price? Also if I do decide to go for it, are there still competent technicians there to do it or will it come back damaged by improvements? It's a long way back to TAG from where I am !!!!!
