Taboo mk II is very responsive to rolling. See no reason why mk III would differ.
The sound can be tailored from warm through neutral to cool, to taste. I prefer neutral. I find it just right between wet and dry - I presume it could be richened if wished (i.e. harmonics are nicely present; not dry; tails extend well). Bass impact is excellent - with my LCD2.1 there is huge 'impact'. Interestingly, I find it more dynamic/lively and with good treble extension with the darker 2.1s. These qualities far exceeded any of the midrange SS amps I tried (Violectric V100; Meier Concerto; and Meier Classic although Classic brings qualities of its own).
Lucid mode - Taboo II, not the 'super' Lucid the III has - is a real plus with phones like classic, non-fazored Audeze's.
At times I have thought it a touch 'slow' on midrange transients compared to - e.g. - the CSP2+. Hard to be sure as the amps are built for different impedances so not apples for apples.
