Is this an right time to buy hifi?

Get a down payment on a shiny new Sanders Magtech stereo amp as well.  
     30 day in home trial to seal the deal. 
    Salk would not cut as @verdantaudio says. They are a very good company.

     The good brands will continuously offer good products & service. 

I'd say if your buying new go for it, if used wait. Covid has driven the used market prices through the roof. Vintage has gone even further up the silly price range, lots of people are over spending on old equipment that's not worth it.  $5k+ for a 70's receiver give me a break. 

@millercarbon.  

    Someone gets it!
