The answer is no. And I don't worry about whether the latest CD player is better. I could understand if someone wants a different flavor, but I serious doubt one could find better. For me, I'm pretty much set.
What is it that he wants to change. The Wadia is VERY sensitive to powercords and power conditioning and isolation and modification. Before dumping something like this, he at least needs to do try these things. I will readily admit that an unadorned and stock Wadia will leave something to be desired, even at this high level.
