Datzeel vs Asr Emitter exclusive vs Devialet


Has anyone listened to any of these Amps and to whitch may be better to drive demanding speakers such as Yamaha Ns 1000 ?
I know this is potencially a strange combination however I would like to pursue my project getting my Yamahas to sing.
I would apprecite if someone could point me in the right direction.

Want to know haw are the analog inputs of the D-Premier ?
Check this extract from Devialet web site :
 
The analog inputs have been designed with the Devialet quality and total lack of compromise.
- Internally routing all the analog inputs as differential signals although received via a "single-ended" RCA connector, with an insulating washer (a very meaningful detail), which makes all the difference: doubles the needed devices of the analog chain hence its cost and removes all the ground noise and distorsion, making the phono ground connection virtually useless,
- Providing a configurable resistive (9 to 460 Ohms) and a capacitive (100 to 700 pF) loading of phono MC cartridge for optimal operation,
- Paying the same attention to noise and distorsions as on the DAC and the ADH amplifier,
- Providing the same extremely wide and ultra flat (see figures below) frequency response as the digital inputs, totally independant from the speaker impedance, except a security sub-bass cutoff at 0.1 Hz for speaker safety purpose (no cutoff in digital)
- using the most optimal and accurate RIAA corrector, volume control and gain stage architectures. Should we disclose that it's the most expensive section of the whole product?
Actually some customers are using their D-Premier as an ultimate RIAA-Analog to Digital converter to rip their vinyl LP collection and build a bridge between recording technologies.
While the Devialet is incredibly good with digital inputs, it's not the game changer with analogue. While its phono section is fairly good, there are plenty better ones out there.

If I was going with an analogue front end I would opt for either the Dartzeel or the ASR Emitter.

As a former NAD M2 owner I would be interested in such a product ONLY IF there were an asynchronous USB input. Many others have done the PCM--->PWM---->analog amplification.(eg. NAD, Lyngdorf) But to my knowledge, no manufacturer has done it with a SOTA input stage. S/Pdif input on any DAC is by definition synchronous and therefore prone to much greater input-related jitter than the best asynchronous USB module/driver available from the industry leaders eg. Weiss, Wavelength, Empirical Audio, Playback Designs, Ayre etc.

I think what Jonathan is saying is correct. Once you go this route, you are stuck with an outdated design that can only be fixed by replacing the entire unit; which is what I have done with my NAD M2.

Regarding the Devialet:

"The HDMI input is not enabled on my review sample, but it should be by the time these get to dealer showrooms. EVERYTHING on the D-Premier is modular and upgradeable. That's the nice thing about this component. It is as obsolete-proof as today's technology will allow. Wireless will be via 802.11 Yes, you can use them together and they can be bridged. Unless I had a pair of incredibly power hungry speakers, I certainly wouldn't need two. And last but not least, it stays cool, even when seriously rocking out. The full review will be out in our Feb 20 issue, on the Zinio electronic newsstand. About 10 days later in our standard edition. This was a long review! I still could have written another 2000 words! Crazy. Stay tuned. The D-Premier will be on our cover, and we only put gear on the cover twice per year!"

I am sorry, what were you saying Mr. Timm?
