Thanks @norust - I am simply going to post what I hear from the DACs listed in my system. I have been here about 25 years so will not be surprised regardless of the comments, but I also know some here will appreciate my observations.
All six of the DACs sound good in their own way and I have no doubt that each one of them would have their fans. That is going to be the hardest part, not to let my biases overly influence my comments so that they come off as judgements. I will try and factually describe what I hear but, yes, I am going to like some of them more than others. Some here seem to get wound up over which of something is the "best" when there are so many variables such as the room, partnering equipment, musical selections, and listening biases and preferences, that "best" becomes an individual choice. I cannot tell somebody else what is best for them. Each of these DACs have professional reviews (which I will link), except for the SMc Audio DAC, so I will try not to overly repeat what has already been written and would urge those who are interested in a certain DAC to read the reviews.
