Agreed, the bass is a bit slow which for me makes the Terminator a bit "boring" for my listening taste. All in perception of course. The Master 7 on the other hand had a little "bulb" somewhere in the low section (specially with 8x Oversampling). Master 7 Singularity is much better in my perception: Very tight bass, fast; spatial and precise, better timing. Just better! R2R7 uses the same digital board I have been told. For me the R2R 7 is more flowing compared to the Master 7 Singularity. It seems more fluent; faster. Never heard a piano this clean!
