Anyone have an experience with Belles Aria preamp & mono amps vs. tube integrated ?

I have 1996 Muse 160 amp & Model Three preamp driving Nola Boxer S2 upgrade, which are 90db efficient. I spin vinyl exclusively mainly classic jazz 50’s & 60’s. I am debating replacing the Muse with either Prima Luna Dialogue Premium integrated or go the Belles Aria route. I have heard neither amps as I live in central Iowa.
I am retired and am considering future maintenance and up keep.

Thank You for your input
