Right now I have an all definitive technology setup. Sm55 bookshelf fronts, pro center 1000, pro sub 1000, sr9040 bipolar surrounds, and pro monitor 1000s for Dolby Atmos heights. What would be the best center channel for me to upgrade to. I think my best bet is to get another sm55 for all three front speakers. The only problem is that I must buy used as they are discontinued. Now besides another sm55 what would you recommend.
