We will agree to differ.
Although you say "this is a common phenomenon with audiophiles" I could respond "this is a common phenomenon with reviewers" with regard to the inevitability of their rating "mark 2" gear as significantly audibly superior to "mark 1" - not least because it encourages the readership base to keep buying the magazine and encourages the manufacturers to keep advertising.
I think we best wait for the double blind listening tests of the 240 opposite the D-Premier - and we will be waiting for a long time because no commercially astute magazine editor or equipment manufacturer will go anywhere close.
Having read your post *1002 where you say "Fuses make a huge difference" I can see we are at opposite ends of the spectrum, which is perfectly ok.
While magazines do have vested interest and influenced reviews dictating as such, this is not 100% true and depends on the magazine or the reviewer. In this particular review case your analogy is flawed as the reviewer already has the older model, also since Devialet themselves have said that there is not much of a sound difference, it would be detrimental not positive for the reviewer to state the opposite, if one had to go by your logic above!
Also if you think fuses don't make a differences then obviously you fall in the category of people, who think power conditioners, power cables, speaker cables, interconnects, isolation platform etc. make no differences in sound, which is crap. I absolutely don't believe that every single tweaks will make a difference nor a $5000 power cord will always be better than a say a $500 one. Fuses do make a difference and its well documented, not by reviewers but by individuals in forums which are extremely well versed in audio and full of knowledgeable audiophiles.
When PS audio came out with their PWD Mk II upgrade one of the changes were in fact the fuses apart from the new board and Paul the owner of PS Audio is an extremely honest and direct person, if he did not foresee that the fuse didn't make a difference, he would not have included it in the upgrade, as it cost them a lot more than just normal glass fuses.
In this regard we are not at the opposite spectrum, as most people would disagree with you that fuses don't make a difference. But in the same note everyone is entitled to their own opinion and for me this is a healthy debate, so nothing personal here, cheers!
