Nice review, summarize what both RME and most others have said. I will endeed stick to my AKM4493, for the best possible tweak there is, for a silly low price, you get a DAC open for external resampling using DSD Direct. In my case the Signalyst HQPlayer. The option of sampling up to DSD256 and apply filters the way I feel sound the best is the most significant feature a DAC kan ever bring to the table. The price for next level, T+A D200 is simply too much, but should be the logical if the weekly lottery strike.
Not that the standard setting is bad in any way, probably one of the better there is, but together with HQP on a powerful PC over NAA it is in my opinion unparalleled for the price. This DAC is a keeper for me, as my ears anyhow is slowly deteriorating and level of computing already at DSD256 means significant computing power.
