Cambridge Audio 840c DAC vs Cambridge DACMagic

Has any one compared the 840c used as a DAC compared to the DACMagic? The Magic uses Wolfson dual differential DAC's, the 840c uses Anagram technologies dual diffeerential DAC's. Both claim to "eradicate jitter" Anybody with a direct comparison?
Good post. I don't know, but would like to, as I am considering purchasing one or the other.

Hopefully someone will come along that can help.
Although not a direct response to your question, I'd also consider the Bel Canto DAC3 which can be found used on AG. They are great sounding DACs.
I already own a 840C and will be receiving a DACMagic within the next couple of weeks, I will report back then.
