bel canto dac 3 cd 2 owners

hi, I have the cd2 transport dac 3 digital front end, and next week I am going to add the new vps power supply, which takes place of the power supply in both the cd2 and dac 3, has any one out there done this yet ? is it worth the money ? I know that better power supplies make about anything sound better, but this is a $2,000 upgrade so I hope its worth it ! thanks, chris
