SMPS power supplies inherently have higher leakage currents and emit more noise than a good LPSU. That's the major reason many people (like me too) avoid them in their systems, they can cause issues in the system whether they improve the device they're powering or not. The last time someone convinced me his SMPS would be alright (this was Alex of Uptone Audio with the Regen) I was treated to a slight high frequency shimmer riding the highs so away it quickly went! 
This could have been system dependant BTW, perhaps I suffered from it because of my P3 Power Plant. For leakage currents to have less damaging effects you're best of with a very low impedance AC feed sharing the same earth. So a non filtering power strip connecting all equipment would be best in this case.
Of course there's good and bad PSU's of both types so it's just a general rule of thumb.
