While I have heard the dual slave-mono configuration before, today I listened to this in my own setup for quite a few hours.
Personally I feel two are critical to overcome what some may be sensitive to from one;
Amir I think I now understand where you are coming from and the 5.3 software on its own would not resolve this, however the dual setup I feel would.
Apart from the sound being even smoother, greater texture-depth-resolution, richer dynamics,etc, a key change is a subtle aspect involving med-to-high frequency intregration (best that I can describe it) and in a dual setup this is fully resolved, part of this can also be noticed with improvement on silibance and maybe subtle phase aspects.
Interesting, some of my older CD recordings now present greater noise from them.
I say interesting because the Devialet is incredibly resolving system so strange this should be picked out even more in a dual system, not a bad thing as it is there originally and I did not find it intrusive but a definite aspect identified in terms of greater performance beyond just the subjective improvements.
So, if interested in the Devialet, one is good but need to listen very carefully, however one should remember the price is incredibly competitive, and for the best sound two is critical IMO (still a very good price for the sound quality).
Only criticism is that I feel some other big amps still have greater swell type related dynamics that may stand out on less sensitive speakers (wonder if this comes back to power reserve and capacitance storage), but the dual system does everything else superb and is up there with SOTA solid state best for long term listening and reference.
I have owned a Devialet D Premier since June 2010. I have never participated in on line discussions before but have followed this one with great interest since it was started last year.
To be honest most of the technical stuff that has been discussed is way beyond my understanding, but reading different member`s opinions of how this unit sounds has been quite enlightening.
After initially being wowed by the Devialet, longer term listening over the following months has left me less so. It could be that perhaps the Devialet is just a little too neutral for my particular listening tastes, I`m not sure. Rock music seems to suffer the most with the sound perhaps lacking authority and a little on the polite side also.
Upgrading the software to the latest 5.3 has improved the sound quality but ultimately I still find myself hankering after a bit more perceived weight from the sound, especially on less than perfectly recorded cds.
After reading some of the latest posts on this subject, it really does seem to me now that to achieve really decent results from the Devialet it is possibley going to mean having two of them to run as monos. Unfortunately, due to the cost, it is not an option for me to do this and subject to a home test of an amplifier that a friend of mine is selling being positive, then I`m pretty sure my Devialet will be put on the used market.
Welcome to WBF Paul and thanks for your first hand impressions of the Devialet D

Indeed welcome Paul
In initial listening the D-Premier has some very impressive sound quality in terms of providing a very neutral sound but without the associated solid state class AB and class D amp limitations (usually along the lines of being lean, too cool, dry, analytical).
That said over time it is other aspects-characteristics I feel we pick up.
Paul, the easiest way to tell if it is a trait with the D-Premier is listen to it in dual slave mode, personally I feel this is the only way to listen to the D-Premier, but as you mention it is the cost to do so.
My gut feeling is that something is happening with the current dumping (where it is combining Class D and Class A) in different parts of the frequency, I feel I can detect some kind of artifact/phase type niggle between the low/mid and the high frequency that is possibly similar to what Amir picked up.
Driving this at louder volume (which is more likely if speakers are not sensitive) and have reasonable space seems to make this attribute more noticable.
Going with dual D-Premier resolves this problem, along with adding greater weight-depth to the instruments, and improving the smoothness even further but without losing the detail or finesse.
Paul, one suggestion; have you tried to plug your CD player's analogue outputs into the D-premier instead of going digital to digital?
This does it will be re-converted back to digital but may provide some subtle characteristics that you like from your current player.
Suggesting this as I would love Devialet to offer different digital settings to offset its excellent but very neutral sound.
Keep us informed on what you feel your hearing and whether you try the CD player using analogue, and what you decide to do in future.

Many thanks for your reply and comments.
You could well be correct with your description, but as I mentioned in my initial post I`m not great on the technical side.
I do find the sound of the Devialet "Impressive", especially with good discs, but have struggled to fall in love with it. It`s just not a sound that I feel I want to listen to for hours on end.
I did try connecting it as you suggested, but to be fair I haven`t done so since the 5.3 upgrade. I did struggle to notice any real difference before but will give another go when I get the opportunity.
Cheers for now,
How about trying with 4 devialets?
Double amplification and dual mono. not sure if it is supported though.
As far as I am concerned I did find power cable and filtering to have a positive impact on sound quality. I have been using a black noise 2500 filter with an esoteric 7100 cable with very pleasant results.
So no dual mono yet for you Bernard
This is something I am thinking very strongly of doing.
The power supply/regulation is quite incredible from a technology point of view.
People hear improvements with various well engineered established high end audio amps/dacs/etc when using cables-filters, you going to suggest the same about those as well?
I hope this is not coming off strong but it is a bit reckless to make that claim Frank without all the information, especially when people will read it and then assume the power supply design is flawed or corners cut, which IMO is not but either way we do not have the facts to make that claim seem so strong.
If there is a limitation regarding this side, it is the smaller powere reserve compared to larger amps and the implementation of capacitors.
To me D-Premier does not compare to those amps with much greater reserves when dealing with dynamic swells, it does well but not as good.
For some this will not matter as it is better than a single D-Premier, for some others they want the full sensation of those dynamic swells that they hear from the big amps.
Just to add it is worth remembering these engineers were involved in the research and design of state of the art telecom/SP core routers-switches-etc, where they must be incrediably resilient and not suffer failures.
Nortel was acknowledged as one of the very best for such core network/sp/telecom gear.
This has fair amount of bearing when considering the power supply and whether it has engineering problems or design shortcuts-limitations.
