While there are arguments to be made for either separate transports and DAC’s, or all in one players, but ultimately I think that all in one players with input capabilities tend to be the value leaders. Digital products tend to hold their value much less than other audio gear, and IME are the products that need replacement the most often, Let the buyer beware. As has already been noted few separate DAC’s are capable of SACD playback.
As for the Benchmark DACs; while I realize that a DAC is more than the sum of it’s parts, I find it irksome that Benchmark chooses to cheap out and use the lesser Sabre chips when much less expensive DACs use the the top of the line Sabre chips.
