You can always try without it and compare. Play some music that does have high(er) level of dynamics and observe whether some compression is introduced with the power filter/conditioner in the system.
It's a little tricky with all-in-one integrated amps like Devialet Expert, because usually you don't want power amp to be filtered (it should be used straight to the "wall") so you don't lose dynamics, but you could get some benefits if you use it on preamp, DAC, transport... With all-in-one integrated you need to check whether the benefits or drawbacks prevail.
From my experience, in order not to lose dynamics, you need to go with the higher models of power filters/conditioners - Audience, Shunyata, Gigawatt, Synergistic Reserach, AudioQuest...
In my case, power line is pretty much fine and what I needed/wanted in my system is a power strip with protection that doesn't affect dynamics and doesn't cost a fortune. I found it in GigaWatt PF-2 EVO, which is in the lower tier of GigaWatt products.

Important note: basic power cable that comes with the strip (LC-1 EVO) reduces the dynamics and upgrade to LC-2 EVO is mandatory.

I also use Furutech FT-SWS NCF Wall Socket.
This is a combo that works in my system, in my room, with my speakers. As I already said - everyone should try different solutions and find what suits best to his system.
