[QUOTE="pwatts, post: 873038, member: 146"] Unfortunately that article is so over-generalized it's of no real value aside from "buy our stuff". Almost every claim they make can be counter-claimed. Especially when low power is considered the advantages of switchers become even less since the 50Hz component can be very effectively dealt with using linear regulators, which is not possible in power amps. The biggest issue with wall warts in general though is not so much them being switchmode but more that they have poor load regulation, transient response output impedance. Jack up to a model with more oomph and from a more reputable vendor and it should already bring significant change. [/QUOTE]
