I was puzzled that I was not hearing the same quality in undecoded MQA files as some others have reported. I came to them with huge expectation bias given the reputation of 2L and the vastly more sophisticated mastering claimed for MQA. I then remembered that I had not upgraded to the latest USB driver (v1.68.19, November 2015). With this installed there did seem to be an improvement in scale, sweetness and focus (although focus could still do with improvement).

Was this just more expectation bias? Try it for yourself and see what you think.
