Basically, the higher the sample rate, the smoother the characteristics and the better the impulse response of the (Antialiasing) filter.
Various room correction devices (Accuphase, Dirac, Trinnov) clearly differ in measurement method, measurement analysis, what they can correct and how they do it.
One needs to go deeply into the details to start understanding these differences.
(And the price may also play it's role.)
A combination of Accuphase SACD player and DG-68 is the only one capable of doing room correction strictly in the digital domain and without the need of an additional AD/DA process.
