Just to continue the MQA contentious debate, I observed some comments on another forum from a DAC designer who had recently visited MQA. Others had been challenging him to describe just what "de-blurring" is actually doing. no response forthcoming but I was intrigued by this comment

The MQA rendering operates at least x8 (352.8KHz / 384KHz) and the faster the better. You DONT get the full effectiveness of MQA without the MQA render block
To which I replied:
The premis of your statement here is that a turntable has superior time domain properties than 192 pcm. Can you elaborate and explain this assertion?
What does an analogue recorded (tape) impulse response look like by the time it has been cut on to vinyl and replayed by the turntable?
No response from JohnW, but I am curious to hear what others views on this might be?
We all know that analogue recording has infinite bandwidth and no limitations in the time domain ....hehehehe
