is ayre qb-9 dac better than cx7e mp?

cheers for sharing, my friend's gone through the ripping and enjoying his download, and he too is in the process of upgrading his software, last time i was around his place he was using fubar? So I was just calculating if the cost of Cx7e mp could get me the DAC+Mac then I'm more inclined to the DAC.
I agree with you Aggielaw, everything matters!
I'm also concerning the fact that I'm moving back to the UK in about 3 years time, have to go through the hussle of converting the voltage to 220, so i might as well get the cdp and sell it. It's a tough one!

just read some stuff from audioasylum Charles from Ayre insisted that the dac is on par with cx5e mp, cx7e mp only sounds better cuz the dac is not fully broken in.
And also to maximise performance with dac, he said it's better to upgrade up to 8GB RAM, there are tests about Macbook pro sounds much better than mini+ with software like Amarra it makes top notch sound. Oh he mentioned pluggin the dac in power filter as well. So there you go.
