Has anyone heard the Devialet D-Premier Integrated Amp/DAC

[andrewd]

Yesterday it was 50 votes to make a model of loudspeaker SAM-ready and today it is 100!

cheeky bastards! at this rate it will be 1000 by the end of the week!

As an aside, has anyone noticed the new firmware for the 170 (200) changed the thermo characteristic of the unit? I noticed that after the update the unit remains quite warm to the touch when it is on standby. It used to be quite cool. I am worried about long term durability with extended hours of heat.

I would say mine is a 'little' warm, cant remember if it went completely cold before the update. I have noticed that the boot-up time seems much faster than before. (D200)

To generate a profile for SAM, Devialet need to have physically one sample of the speaker and conduct some acoustic measurements.

Why can't it be done by the user with a microphone and some software ?

Could be done if you were a highly skilled engineer with the appropriate equipment and knowledge.
But I guess Devialet people prefer to master that themselves.

It's more than just acoustic measurements. From the ADH/SAM whitepaper:

Devialet engineers have developped a characterization protocol including electrical, mechanical
(laser interferometry) and acoustical laboratory measurements to be able to model the exact
behaviour of any loudspeaker. They have industrialized the process to be able to develop SAM
processing for any speaker, from initial measurements to final robustness testing. It all happens
at Devialet headquarters in downtown Paris.

Since you can power the Devialet on and off now using the remote app they must keep at least some parts (including those containing WiFi/ethernet of course) powered on at all times. So it'll use more power in standby and thus create more heat. My D-Premier is in France now for it's 240/250 upgrade otherwise I would have checked the power consumption before and after setup of the 7.1 firmware (my PS Audio P3 makes this very easy). Maybe Devialet will make it an option to disable this remote power on/off functionality if/when we ask them.

I read on a German forum that the D-Premier upgrade offer will end at the end of coming July and that the bi-directional USB functionality will become available in a few weeks. (http://www.wmp-forum.de/verst%E4rker-384/devialet-24967/index-213.html#post187848)

I hope they've been measuring run-in speakers and not brand new ones!

 

[Ekmanc]

It's true I just got confirmation from Devialet that the D-Premier ----> D250 upgrade possibility will end at the end of July this year.

 

[Nightmare]

Of course it will. There is no Devialet 240 (now 250) in their programm at all any more.
Kind of crazy. And the 170 is a 200 now. And suddenly dual-mono is possible? It sucks.

100 votes since today. Devialet disses their users. Bad behaviour.

 

[Revel Salon 2]

I would have bumped the 240 to 300 instead and kept it in the lineup for those who don't want dual mono... 120-200-300-400-800 would have made sense.
for some 400 is too much and 250 not enough ;-)

 

[Ekmanc]

Not sure that it was possible to push the 240 all the way up to 300 without affecting temperature and life length too much.

 

[Nightmare]

And I gues 300 would have been no problem at all - maybe 280.
But so it´s rationalised by an upgrowing 170.

Whatever - 250 is enough for me. And sound is ´still´ brilliant

But knowing the actuall option I might have gone for a 170 last year and a second one today

 

[Ekmanc]

I would definitely have gone for a 170 if I'd known this before.

But oh well, time to send my D-Premier in for an upgrade I guess before they close down that option.

Thanks, what is bi-directional USB? Is there any explanation from Devialet on this technology?

I haven't read any explanations from Devialet on this functionality yet but I think it means that the USB port, which is now only an input will also become an output to a computer (and/or maybe another USB DAC) similar to the digital RCA/COAX output you can configure at the moment. I'm sure Devialet will give us the details as soon as they are ready to release the functionality.

edit: I originally read about the functionality before the 7.1 firmware got released at a website of a Canadian dealer/importer. He wrote this about the functionality:

* Bi-directional USB which allows easy digitalizing of your vinyl records directly into your computer

Same here, but I bought my D-Premier in Feb. 2012 and at that moment the moment of introduction of the new models would take another 15 months or so. My D-Premier is in France right now for it's upgrade, hope to receive it back very soon; I miss it dearly!!

I definitely understand that, please do give us a little opinion once you get it back. I'd love to hear what you think of the improvements.

My reasoning is that if 2 dual mono can output 800 watts then 1 single should be able to do 400 !! I might be way off..

Very good point
