I don’t have experience with those integrated amps, but I think the character of the preamp will be preserved using class d. I think a nice tube pre and a class d amp would be great. For me it was all about whether the speakers will respond to the additional power. My McIntosh was going into protection mode more frequently than I liked and that was an additional incentive to try class d. My wife complains about how loud I play my tunes. Lol. I also like having a back up amp in my main system. Don’t be intimidated by the naysayers to try class d.
High end Class D amps?
Just an observation and a question. Are there 'high end' Class D amps out there that are just as good as Class A, A/B amps? I realize that's a sensitive question to some and I mean no disrespect---but whenever I see others' hifi systems on social media, all of the amps are A or A/B. There's always Pass, McIntosh, Moon, Luxman, Accuphase, etc. Where are the Class Ds? For folks out there that want more power for less efficient speakers and can't afford the uber expensive Class As, A/Bs, what is there to choose from that's close to those brands? Thanks
