Sony SCD-777ES vs current Players

I have been using my Sony SCD-777ES SACD Player for 10 years without any problems, it's built like a tank and sounds great to me.

However, I'm looking to buy a new Blu-Ray player and wonder how current universal players compare with my machine in terms of Audio playback of CDs and the occasional SACD.
Also, how do modern stand alone CD players compare with it?
Am I able to improve on the sound quality with a modest outlay?

Thanks for your help.
