adg,
Thank you very much for your response! I'm guessing the CA 851C is better but not necessarily by an order of magnitude, and that alternative IC's and fuses would be the more practical choice at this time. I will eventually upgrade my CDP/DAC at some point in the future. I read reviews about the 840C and many said that it made for a great transport, so maybe my focus should be just a new DAC as I mentioned about >80% of my listening is using the 840C as a DAC.
