Tidal are right up there with Gauder, Avalon & Marten in terms of implementation of Accutons. I have a lot of respect for Leif Olofsson (Owner/Designer of Marten) who did a cracker of a job on the Coltrane 3 which, like the latest generation of Tidal speakers, use the latest Accuton Cell Concept aluminum honeycomb sandwich dome bass drivers (only in the OEM graphite coated spec) which are right up there with the latest Magico S7 aluminium/graphene bass units. But Tidal make the most superb cabinets and I think qualitatively are on another level to Avalon and Marten. Gauder also make superb cabinets, however they're using older generation Accuton drivers (likely due to cost). As they say, you pays you gets.
I (personally) think Magico offer better bang for the buck which is helped by their unusually high percentage of in-house design and manufacture, which coincidentally allows greater design freedom, quality control & the ability to achieve tighter tolerances/driver matching.
