I would not worry about HDCD.
I don't know if the Sony will provide a significant improvement in sound quality over the Rega. All I know is that I've owned the 5400 for 3 years or more, and it's been reliable and glitch free.
I have a Sony 333ES and a Sony XA777ES, both decent SACD players, particularly the latter - and in my case, this unit was very much modified; but there is something special to the sound from the 5400, especially on CD where they seem to have done some magic.
Regards,
