Post subject:  Building a 6ch amp with crossover for 3 way cabinets

Hello everybody, thank you for your time... I am working on an amp with crossover for a pair of 3 way bookshelf speakers. I am thinking about using 3 TDA7498 and a crossover board with NE5532 op amps. I am wondering about the "processor speed" of each amp being different and causing each driver in the 3 way cabinets to be out of sync. I have seen some things about a master and slave sync pin on these boards to synchronize the speed of multiple amps so that each speaker will be in the same phase if that's the right term. I've run this crossover board and 3 TDA7492 amps for testing the board and it sounded fine... So that is my first question, and my next question; Is it likely that I can replace each of the NE5532 op-amps on my cheap crossover board with OPA2134's? I looked at the sheets and the pins should line up as the same configuration, and voltage requirements are similar. I read about people replacing NE5532s with OPA2134s on maybe headphone amps or preamps or something but I wonder if in this case it might alter the crossover points or performance or something. I appreciate any time or thought about this, have a good day.

I would NOT worry about that whatsoever
