Why have the prices of Marantz and Sansui speakers have gone up so much? Whyyyy???

There is one speaker from that era which have always had a following the Realistic (Radio Shack) Mach 1.  I only know people have sought them from the start and haven't hard any myself.  They are still popular but have gotten panned by people used to current audiophile standards, i.e. expecting sound quality equal to or better then todays offerings. I have some old Marantz book shelf from a garage sale I have never used,  perhaps I should put them on auction.

Marantz and Sansui have many followers/collectors.
Happy Listening!

@kosst_amojan you have to listen to vintage tannoys jensen ev Goodmans etc blow your mind musically pleasing

@jafant i love and own lots of Marantz and Sansui equipment but im not fanatical or biassed to acknowledge that their speakers are terrible.
I dont worship everything marantz or Sansui does because its a sansui or marantz
