    Overall improvment ... Reduced price, around 60Ç and it exists only one 5V model. The hdplex tested was the 300 watts model. The SBT doesn't use competition voltage regulator, so, it seems logical to hear some effects with an optmized power supply.
    On a W4S recovery, it is more difficult to hear an effect with a ifi ipower.

    The interesting thing is that the ifi power supply does not appear to be a linear power supply. It has an input voltage range of 100V to 240V which is impossible for a linear supply.

    Good point. They don't claim it is linear, and it would be hard to make a linear power supply that small.

    That's actually refreshing. The belief that a certian design principle is always better is not good .

    This whole tread is based on a myth that linear is always better for everything.

    We can instead have good vs bad designs linier or switchmode .

    And also does it really matter much when the ps is actually working as it should given how the Touch is designed ( not so much )
