New DAC for Sony SCD-777ES SACD player.?

I still love my Richard Kern modified Sony SACD player. In my ears better than Oppo UDP-205 that I bought to replace it with.  It is now almost 20 years since these came out.
Like many of these units, the SACD laser is not working as well. But CD is still flawless.
How about buying a DAC for Redbook?

Would a Schiit, Benchmark, Mytek, iFi, or Ayre make a real difference.

(The musical experience from my analog turntable set up is still much superior.)
