About the Burr Brown vs. Phillips: There is nothing in my manual that says one way or the other. Mark Allen told me he uses Phillips and not Burr Brown. Here is a portion of a Jolida 100 review:
"The JD-100A is a departure from most high end machines: it shuns the expected Burr-Brown D/A converters in favor of Philips chips. This is totally intentional. JoLida's design goal with the JD-100A was to build a CD player that was very linear, thus very listenable. This is the main difference, in my opinion, between digital and analog music reproduction. Analog, to my ears, is very linear. Many CD players tend to be bright and analytical. These players reproduce all of the detail, but they tend to be very fatiguing, especially during extended listening sessions. Listening to music should be enjoyable, not fatiguing."
So there you have it. The seller probably thought by making his claim the unit would be more attractive to a buyer. You are rapidly becoming a knowledgeable buyer.
About the tubes. Just listen and don't worry.
