I plug both Bricasti M28 amps into the PSM156. Excellent results! The Puritan psm156 does not constrain the amp’s ability to pull needed power (volts). The PSM156 does not have an internal transformer and does not daisy chain the 6 outlet plugs. Each component plugged into the psm156 draws on the full available voltage from the corresponding wall outlet. The psm156 simply purifies unwanted hash/ noise from the incoming electrical stream. I have a 20amp dedicated line that feeds my psm156. I highly recommend the Puritan Ultimate power cord.
