upgrade is back

[K4680]

For those thinking about the upgrade, it might be worth spending some time reading through this thread.  There is a lot of waffle and nonsense in some posts, but some gems of information included as well.

In summary, the sound quality improvements with the Pro are related to more power, improved power supply /power management and improved ADH.  So Devialet have publically advised the technical reasons why the Pro is capable of better sound quality.  It is also interesting to note that with respect to sound quality performance, Mathieu Pernot has stated that the theoretical idea would be infinite power and the lowest possible ratio of class A to class D in the ADH.  The last point is a little counter-intuitive, but it was covered in the above linked thread.

So there are measurable technical reasons why the Pro might sound better, as to if the upgrade is worth the money for improved sound quality or features, I would say this is a very personal choice, there is no absolute right or wrong here.  For the record, I listened to a D800 and a 1000Pro back to back, and made my decision to get the 1000Pro based purely on what it offered in terms of an incremental improvement in sound quality, I was not that interested in the features that the CI board might offer.  I have not regretted this decision.

There are so many variables here, for some there will indeed be a better "bang for buck" option, say for example room treatments, although there are limits here too, some may already have optimised the room as far as practically possible, in which case spending more on electronics will yield more than spending yet more on room treatments.  Some speakers are more demanding than others, so here some will benefit more than others from the improved power and power supply.  Plus, an incremental increase in sound quality will matter to some people more than it does for others.  So I think it is wrong to generalise too much, for some the upgrade will make sense, for others, it will not.
