So, who is planning to upgrade to a Pro?

I will also be waiting to see. I am sceptical about the new Devialet OS thing that I guess is mandatory when the new streamer board comes along. There is simply too little information about the real improvements.
I am also deeply worried by something Confused wrote reporting from the Oxford Audio event. Mathieu Pernot  says Devialet only uses measurements to verify their developments. They never listen    Pernot says something stupid about trusting lab equipment but not his listening skills. While it is good to have measurement backup when you develop audio reproduction, not listening to changes you make is bad practice in my book. I do not believe the original Devialet ADH was developed by measurement alone.
I may move on to something else for this reason alone.

I think that Quad, those terrible British amplifiers used to only use measurements for their amplifiers and never listened to them to test either.

Goldmund too I have been told.
The problem with listening evaluation is that the placebo effect means that it is quite possible to hear a difference when there is none.
I have listened to music with Mathieu extensively as well as discussed many technical aspects over the last 5 years. I would trust his judgement 1000x more than any of the opinions I see frequently on hifi discussion forums, personally. Many of them verge on the lunatic.

No, the human brain is an infallible piece of measuring equipment and never makes mistakes or confuses anything, a little like HAL.
