Upgrade from Emotiva XPA1 to Bryston 28bsst2 or Pass X350.8

Hello everyone, this is my first post. I have fairly recently begun building up a system after many years away from owning any decent home hifi equipment. I started off with Maggie 1.7 speakers running off Emotiva XPA1 mono-block amps. I am now driving my Revel Salon 2 speakers with the same Emotiva XPA1 Mono-block amps, with a Bryston BP-17 pre-amp. I have been using the Emotiva amps for a few years, as starter gear for re-entering the hobby, however I would like some good feedback on potential replacement amps that would significantly improve the already amazing sound quality of the Salon 2 speakers. I was thinking either Bryston 28bsst2's or Pass X350.8 or similar. What do y'all recommend for driving the Salon 2 speakers. I would like to hear better sound for jazz at low to mid listening levels, but still need enough power for rock music at higher levels. Thanks.
