Yes your speakers very much so have major liabilities being that old and not rebuilt most everything is limited
capacitorsfor sure wear out ,and most likely real crap
electrolytics in there which should not even be there resistors also . Which just this alone would totally rob the system of fidelity and dynamics . If the amp too is old rebuild it capacitors , resistors
wiring ,all can be be drastically improved 20 years ,even 15 years capacitors are known to leak ,or dry out . I have been through
this in the past ? First decide do you want solid state ,or Vacuum Tube, that will determine how efficient your Loudspeakers need to be ,and how Loudin SPL levels you need ,and room size how far away you sit. How powerful the Bass , or maybe a great monitor
with excellent subwoofer-s. Many options , your $$ budget will
determine this ,how about preamp, or integrated ?
