Why do you say that measuring dacs are worthless? Of course measurements are needed so that one knows whether the DAC is functioning properly but after that listening comes into play. Not all DACs that have high SINAD sound good and not all DACs that have low SINAD sound bad. Case in point is the Fiio K5 Pro. Measurements are
here. The results are 82 SINAD in the
red band and it is recommended by Amir himself !!. Here is the SINAD graph from the link... I highlighted where K5 Pro is.

I own this DAC/AMP and I find no faults with the unit even though the SINAD is low and it is agreeable by Amir I guess after listening to it. We shouldn't give all credit to measurements but listening plays a part too.
I think allowances should be made on hearsay at least to owners of DACs when they hear differences between DACs they
owned. They have more experience with the units and have lived with them. Anyway this is my 2 cents.
