Shall I move away from Devialet ??? where to go?

My thinking is that the Devialets are amazing amplifiers and for your described sound preference, maybe Chord's new Ultima line might be a step up depending on your power needs.  Technologically, they are pretty amazing amplifiers.  That being said, I would be more focused on speaker upgrade than the amps.  You also have good subwoofers and could consider a lot of options including stand mounts.  

If you are looking for fine detail and an analytical sound, I can think of three speakers I would look at very seriously.  

Marten - The Oscar and Parker lines could be interesting for you.  They use Accuton drivers which are renowned for their accuracy.  Marten delivers pretty amazing quality at fair prices, all things considered.  

Vimberg - is a bit pricier and they also use Accuton drivers and these speakers are just unreal.  Tidal DNA, they are simply jaw dropping in terms of quality but the price does sting a little. 

Verdant Blackthorn 1 - These are mine.  We use Eton instead of Accuton drivers but this speaker is all about detail.  Highly analytic.  The carbon fiber cabinet is dead, and the level of detail delivered is perpetually shocking to me.    

PM me if you are interested in any of these.  

The carbon fibre cabinet is dead...sad....otherwise, once the Devialet (do you pronounce the "t?" I always wonder about that...and I do mean "always"...it's a nightmare) has lost its luster you have to start from the beginning with an all tube system including a single ended tube amp, requiring efficient speakers. Do that and get back to me once it's done...

Put the lime in the coconut . Then call me in mor or or  or ning.

@verdantaudio Thank you for your response. 
Unfortunately, I have limited choices here in Dubai ... can find KEF, B&W, Wilson, Focal, Martin and few more.

I tried Wilson Yevette with Devialet 200 in my dealer's store and the SQ was amazing especially the mids and the soundstage.

Also I tried the B&W 802D3 with Krell but I didn't like them at all. the sound is too harsh and soundstage is not that good. I heard a lot about them but I am not sure why it did'd sound good. Maybe because of the Krell amp !!

Have you tried and of these speakers with Devialet? I'd like to know your opinion.

Any other recommendations??

I have only had a brief stretch with a Devialet amp I had on trade.  Had a longer stretch with a Micromega which I found quite similar in terms of sound profile.  I found both deliver amazing detail and are quite neutral and will expose the flaws in any speaker.  

I am not shocked at your opinion of the Krell & B&W combination for a variety of reasons.  

Prior to starting my company I spent a bunch of time demoing every standmount and small floorstander I could under $20K (and a few over) and these three were brands I spent some time with.  I always found something I didn't like which is why I ultimately started my company.  

I think there are three others that are standouts and I would look at very seriously:

If Marten is available, you must hear them.  Brilliant speakers and will deliver an amazing soundstage.  The Oscar and Parker lines can be had at modest prices.  

Wilson-Benesch's Geometry series if they are available.  One of the best engineered speakers in the world. These will be smooth and natural and soundstage is utterly amazing.  

Vivid is a little pricey and styling is not for everyone but Laurence Dickie is one of the most brilliant designers alive.  If you like the styling, you will never own another speaker.  If you don't like the styling....

As far as brands go, I would seriously look at Wilson, especially if you have had a positive experience. At a not crazy price, the Sabrina is amazing. I have listened to them driven by a Devialet integrated. I have demo'd Vienna Acoustics and Spendor as well with Devialet and these would be supremely good choices.  

I personally will export to Dubai for my brand Verdant Audio but there is no chance you would hear them in advance.  I would take them back if you don't like them but return freight will sting a little.  I would also revise my recco from your experience with B&W and advocate for my Nightshade.  The Blackthorn has a slightly forward tilt to it's sound profile I don't think you would like.  I ran both my speakers with the Micromega and would be surprised if you weren't happy with the combo but it wouldn't be an easy purchase.  

Congrats on the T2, it's a super piece of gear. I've had mine about 18 months.

I love my Focal Sopra No. 1’s with a JL Audio F112 sub. Look to move up to the Focal Sopras or Utopias if you like the Focal sound
