Loxjie A30, smsl a300 or something else for turntable and CCA

[Zuma_12345]

This is my first post. I have an old Technics SA5160 reciever connected to CCA and turntable via Fosi phono stage (tubes). My speakers are monitor audio bronze 2. I live in an apartment and do not play loud. Like to listen to jazz and acoustic music mostly. It sounds ok but especially bass is muddy, the technics is from the 70s so I figure i might buy a newer class D and get remote etc. What would you recommend for my setup? Have read that maybe the rca is lacking in A30, is that better in the smsl?
