I only have the SFR MT100 Pro, TRN Kirin and this Dioko and sicne I don't really like the MT100 Pro so I may compare the Kirin the Dioko here.
In general, without much burn-in, I find the Dioko lacking impact, there is not a lot of height in the bass region but more width and more reverb. The mid is slightly recessed so it can sound a bit weird occasionally. With my current setup there is too much treble emphasis but the clarity is indeed boosted and can be fatiguing easily. If you know what I mean, the throat voice is shifted to the lower part due to the recessed mids and emphasised upper treble so the voice can get thinner.
In comparison the Kirin after 80hrs of burn-in has slightly lower clarity but similar resolution. Mid is not recessed and there is enough bass impact and bass immersion.
This is just based on my OOTB experience with the Dioko and my impression may change after time.
And and the Dioko is huge as expected.
