For that scenario, there is this bad boy. According to the official specs, the MP-S201 conservatively outputs 50 watts Kl.A and 1400 watts Kl.A/B @4ohmsI'm a BIG fan of MBL in the right room (!!). I don't think the 100w of the Vitus can drive them efficiently. At 80db (and confirmed by John Atkinson's measurements), you would be wanting a lot more power IMO.
