Answering the last part, I didn't know that a talking point would develop that 2X was no good and that only 16X had value. This came about post my testing. How is that a 2X upsample is no good when it invokes the same super long filter? How is that the magic only exists at 16X and all disappears at 2X?
As I understand it, the 16x oversampling allows for the proper use of noise shapers which deals with the noise issues you identified in the 2x and 4x testing where dithering was used instead of noise shaping. Reducing the noise floor can only be beneficial and I'm surprised this wasn't measured and discussed in the original review given that you were provided with a Hugo 2 for the testing.
As to the rest, didn't the two of you in the video ridicule me for not testing 16X against bypass saying it is seamless? Now you say that test is impossible blind because it is not? It seems that both you and Rob didn't know about this delay. I tested bypass to 2X because it is completely seamless.
There was no ridicule there. I stated in the video that I assumed you were not aware that you could test by going from 16x to bypass instead of bypass to 2x. I have a TT2 and M-Scaler on the desk in front of me right now and there is an identical delay when switching all modes - from bypass to 2x, 2x to 4x, etc. Perhaps this is different with the D70s you were using, but I don't believe the gap from 16x to bypass is significant enough to cause auditory memory issues.
Still, I don't know why it should stop you from running this blind test. Have you leave the room between switching and come back when it is changed (or not). Do this a dozen times and see if you can identify the difference.
So, on one hand you are saying how important it is to conduct listening tests with no delay and then you are saying I should leave the room while it's changed and then come back? Which one is it? That would suggest then that you could have actually tested with 16x upsampling because the switching delay doesn't matter. I don't understand why you chose 2x if this extended delay is acceptable for my tests.
