I really don't know what is your intention to test a product that is discontinued few years back in year 2020.
The intention was to identify if the core amplification technology Devialet has offered since start is competitive with state-of-the-art in amplification. The 200 came out in 2015 it seems so less than 5 years old. Amplifiers do not become obsolete quickly so in this regard, this amp is as relevant today as it was when announced.
Professional reviewer uses brand new unit for testing, and they talk to the manufacture if they encounter issue during the testing, get the communication happen, then continue to test, finally they publish the detailed background, process and result.
You mean paid reviewers. They work for magazines or bloggers who get free loaner equipment from manufacturers. Naturally manufacturer wants to sell new products so that is all they offer those reviewers. The partnership there is between the manufacturer and reviewer. The consumer does not enter that equation (not directly anyway).
We are different in that I don't get paid to review anything. My model is to rely on membership to provide gear that they like to have tested. This removes every trace of commercial conflict. So if you are on the side of customers, you should like this model better. If on the other hand you are on the side of the manufacturer, then sure, you would be upset as you are.
In this case an owner sold his amp to a US based member. The two agreed and were interested in having me test the unit on its way to its member. That is what I did, and what I reported on. Nothing was hidden or represented as being current product. This was clearly identified in the first paragraph of the review:
If the new version doesn't have the same high frequency power limit reported by me and Stereophile for a generation back, then you as an owner of one or the company should offer it for testing. So far no such offer has come.
Over time, I am sure we will get access to more Devialet products to test. We have patience as there is plenty of other gear to test.
