Recommended vintage amps.

Thanks to the many good postings here that got me into buying a few good vintage analog tuners and mini monitors on the recommended list.

Now I am considering any good vintage integrated amps to match my old Kenwood and NAD tuners. Currently I'm using a NAD 3020 and Sansui AU-217, which both are so worn out and looks like ready to retire. Or should I just get the newer (budget) integrated amps but are they sonically matching with vintage tuner and speakers? My speakers are Acoustic Energy Aegis 1, B&W DM302 and Paradigm Mini Monitors.

Thank You for looking.
