I may be absolutely wrong, but my impression of the CD staff that are trying to answer the technical questions posed by backers are basically "middlemen" who are doing what they can to get information from someone in Taiwan who has actually designed and is building the Pro players and the PHA. This campaign reminds very much of the Nationite Sflo2 experience. Nationite worked through Teclast to get their name on a Teclast player, and Nationite suffered due to delays caused by Teclast. I think that CD is doing something similar. There appears to be a company (? under direction of Thomas Chen) in Taiwan who is making all the decisions on these products, and they appear to be making some modifications that are most likely outside the control of CD. It appears to me that CD is a "front" for the manufacturing company, and unfortunately, they will take the blame for changes they are not responsible for. Hopefully, the folks that we are communicating with at CD have passed along backer's concerns to the manufacturer, but who knows what impact this will have in the final production of the Pro's and PHA. Therefore, the members of the CD campaign who are trying to answer the questions posed re: ESS DAC and HO impedance are probably not dodging the questions, they probably just don't know the answers yet...
