RE: Latest hifimediy Tripath T4 amp module




I have a Topping TP-60, very nice older tripath amp. Uses dual-mono power supply setup, very solidly made. Have a look at the picture. This is a lot of amplifier for $200 retail. Detailed, somewhat tubey-sounding (slightly sweet) with good bass extension and control (within the limited amount of power provided- this is not a giant Krell, Pass or Levinson arc-welder)

Big analog amps have considerable constant current consumption, they need much larger capacitor reservoirs than a switching amp which has almost no idle current drain. Even preamps with energy-consuming shunt regulators will want big capacitor banks. Switching amps are a different animal, and while they do need current reservoirs the requirements are different. With a switching amp you want some ampacity but more importantly you want the lowest source impedance power supply you can get at the frequencies that the switch uses. That doesn't always translate to giant electrolytics.

Very neat job there on the build.
