It all just depends on what DAC would you prefer to rely: of 541i or the receiver's one. I had 541i with 761, and my opinion that DAC in 541i is far better then in the receiver, my dealer confirmed me that 541i circuitry is well refined in comparison to any of their receivers.
And, the best use of the digital out is to connect a good stand-alone DAC of better quality then 541's own. This would give you more flexibility, while I'm not sure it's money-wise. And, don't forget to get quality interconnects!
