Currently, I am using a MSB Link DAC with my current older Marantz receiver. I love this DAC, when compared to the Marantz's internal DAC there is no comparison. Here is my question, if I upgrade to a new receiver (I'm looking at the Rotel or NAD receiver), are the internal DAC's on these new receivers improved enough, so, I could sell the MSB? And, if you're going to use these new processor's like Dolby Pro Logic II, do you need to send the receiver a digital feed (thus by passing any other DAC)? Hope this makes sense! Bottom line I guess is if I buy the new NAD T-752, will my MSB Link become obsolete.
