Mobile Fidelity Surface Noise

Recently bought my first two MoFis in a few years - 'Sinatra in Paris' and 'The Cars.' Cleaned both on a VPI 16.5 w/ the VPI fluid. Both have an unacceptable level of (the same) background noise - kind of a shushing sound with the occasional tick. Played some other LPs after for comparison, inc. a vintage MoFi and some regular issue stuff. The noise was not there, eliminating a set-up issue. Has anyone else had this problem with the new issues? Is it mold-release compound, or the old saw they used back in the day ('i.e. "MoFi does not de-horn its masters, so you my hear the occasional tick or pop until the record is played a few times..."), or just lousy QC? Disappointing, to say the least.
