Upgrade D-Prem?

[f1eng]

So the extra £4k or so for the 250 is just for a slightly different case? That's one expensive box! And if all the case does is improve cooling, buy a fridge to put it in or buy a fan! The suggestion here is that the Devialet's "marketing positioning" is simply a way to get more money, via the 250, out of people who have more money.

TBH the case and power supply are usually the most expensive parts of an amp. In the Devialet the power supply is clever rather than expensive.

In terms of what actually happened your story is upside down.
The D-Premier came first as a premium product in a cast and hand finished case made in fairly small quantities. The 240 is an update of that.
The 170 and 110 came along as a cut price version using the same technology in a (much) cheaper to make case.
The heat sinking is a very expensive part of any case.
It does not surprise me at all that the 200 is a lot cheaper to make than a 240/D-Premier. It may be the case that the D-Premier was the most expensive of all Devialets to make.

So your assumption is incorrect IMHO, the first product was expensive hand made in small quantities and the subsequent models are a cheaper to make design, more mass produced.
I would not imagine that many people will buy a 250 any more at all, and the 800 will probably be mainly confined to those of us who updated a pair of D-Premiers.
The cheaper models make much more sense to new buyers requiring 400 watts or less.

If you prefer having a noisy and bulky fridge in your room (which probably wouldn't be effective anyway) help yourself
