PS Audio DL III DAC with Arcam DV78? Should I?

I have an FMJ A32 with a DV78. I am actually surprised at the performance of the DV78 as a transport. Ever since I first laid ears on it I thought I ran into a bargain. I am also an audio addict and always looking at upgrading for two channel audio. Do you think that the PS Audio DL III would be a drastic upgrade? I have not had a chance to hear it and no one stocks it. I think the upconverting would be a plus and changing from the rca outs to clocking the digital would also be huge. But... maybe not. Any opinions?
Thanks!
