Forgot to report back.
I ended up purchasing the SIA-025 MK2 after auditioning it in my system against my ex Diablo 300, Audio Analogue Absolute and even Audionet Humboldt.
I much prefer the Vitus house sound with my speakers smooth, liquid and very organic.
Will probably upgrade later on to SL-103 linestage + SS-103 stereo amp and MP-D201 Mk3 DAC.
