Denon or Marantz has Analog out = bypass the DAC altogether.
He's got a ground problem and changing the grounding setup is no guarantee of improvement. Breaking the ground circuit is much more likely to help, so going optical is the best way.

It belongs to the customer and I doubt he will want to pay those prices
This is a really unclear statement.
What belongs to the customer? The Sony with the problem? Those prices for what? For no DAC? For a converter? You're asking him to pay for a new Blu-ray player without, as far as I can tell, consulting the Jensen Transformer papers on ground / hum problems. That's the place to start.
