     · Due to improvements to the main circuit board, the impedance of the passive part of the RIAA network has been reduced by over a factor of 3 compared to the original 2.0 version. Lower impedance reduces the effect of capacitor dissipation which in terms of sound quality improves clarity and definition, while also slightly improving SNR.
