I got the files (K-series SACD players HA_2 async. firmware updater + new MacOS driver) from Scott Sefton yesterday. I have just flashed the new HS_2 async. firmware on my K-03 and installed the new driver on my Mac Mini. I have listened to a few hi-res. + CD ripped FLACs and it seems to have solved the problem. So far so good! BTW, after you have flashed the new firmware on your K-series player you have to power cycle it in order for it to be effective.
Now I have to figure out where and how to have my K-03 upgraded to the new USB board for DSD64...
